Buy The Bonus Slots

Best new bingo sites selection - Buy The Bonus Slots

Following action by the Gambling Commission as of October 2019 it is no longer possible in the UK to play slot games with a straightforward “buy the bonus round” facility and this is being actively policed.  Many games still enable players to collect coins towards an eventual purchase of the bonus round and/or gamble the bonus round once they have triggered it.

  • Play Rainbow Riches Megaways at Cash Arcade
    Deposit £10+ To Open Your Loot Chest - Top Prize 500 Slot Spins

    Rainbow Riches Megaways sees the Megaways treatment given to arguably the most popular slot of all time (as far as UK players players are concerned, anyway).  The base game is very similar to other Megaways gems such as Bonanza – it has the familar horizontal reel at the top and cascading wins. The Super Gem symbol, which transforms all gems on the reels into the same gem, is also nothing new.  The bonus round is also typical of Megaways slots rather than of other Rainbow Riches games – it is free spins with an increasing multiplier.

    Where it gets interesting is in theways in which the bonus round can be triggered apart from by the usual 4 bonus symbols.  The Buy Pass triggers it instantly for 100x stake and if bought, the bonus round can be gambled using the Take A Chance feature, which awards a better bonus round or nothing.  Players can also save up for the bonus round by using the Bank feature which allows some or all winnings to be held to reduce the price of the Buy Pass (if you leave the game without buying it the winnings return to your wallet)

    Rainbow Riches Megaways has RTP of 96% and this goes up to 96.661% – 96.863% if the Buy Pass is used.  The “Take A Chance” gamble does not have a house edge.  The game can be played from 20p a spin.

    * New players only, min deposit £10, £8 max win per 10 spins, max bonus conversion equal to lifetime deposits (up to £250), 65x wagering requirement and full T&Cs apply

  • Play 300 Shields Extreme at Fun Casino
    Deposit £10+, Get 100% Slot Bonus Up To £123 & 10% Cashback

    300 Shields Extreme by NextGen is the sequel to the notoriously high variance slot 300 Shields (inspired by the film “300” which gave birth to the catchphrase “This is Sparta!”).  It has 25 paylines and is played on a classic 5×3 array.  The main differences from the original game are new HD graphics and the introduction of the Buy Pass which enables players to go straight to the free spins bonus round for 65x stake.

    It’s the kind of bonus round that has the potential to be absolutely insane, but also often disappoints.   It starts with 5 free spins with warrior (wild) wins doubled and can escalate through 4 levels (adding more free spins as it does) depending on the number of shield symbols collected while the free spins are playing.  The 4th level has an eye-popping 300x multiplier on the warrior wins – you can’t get much more high variance than that!

    300 Shields Extreme has RTP of 95.299% (95.658% with Buy Pass active) and can be played from 25p a spin.


  • Play Return of Kong Megaways at Foxy Games
    Deposit & Play £10 on Slingo, Get £10 Slingo Bonus

    Return of Kong Megaways by Blueprint Gaming has the classic Megaways features of cascading wins and a horizontal belt above reels 2-5 of its 6 reel array.  What makes it more than just another Megaways slot is firstly its reuse of the much loved video game inspired lead character from King Kong Cash and secondly the choice of ways to progress directly to the bonus round if you don’t want to wait  – if the operator has enabled the Bonus Bet button (not all of them have).

    100x stake buys the regular bonus round of 12 free spins with an increasing multiplier.  Collecting Golden Monkeys during the bonus round awards extra spins and upgrades the minimum number of Megaways per spin.

    150x stake buys a spin of the mystery bonus wheel which offers the opportunity to short circuit the process of collecting Golden Monkeys.  It awards a random number of free spins with a random Golden Monkey upgrade level (so starting with a higher minimum number of Megaways).

    Return of Kong Megaways can be played from 10p a spin and has RTP of 96.13%

  • Play Who Wants To Be A Millionaire at Spin Rider
    Deposit £20+, Get100% Slot Bonus (up to £300) & 50 Bonus Spins

    Who Wants To Be A Millionaire is the latest release from Big Time Gaming, the creators of Bonanza and of the Megaways system.  Big Time Gaming are known for the extreme high volatility of their slot games and thrilling bonus rounds – and Who Wants To Be A Millionaire has by far the most insane and ridiculous bonus round yet seen.

    The base game plays very much like Big Time Gaming’s earlier release Extra Chilli, and the bonus round builds on a concept first seen in Extra Chilli – the ability to gamble the bonus round in the hope of getting a better one.  In Who Wants To Be A Millionaire, the entire point is to gamble the bonus round and just as in the TV show, the player has to choose correctly from four options at each step to increase the number of free spins.   Win at every step and the 8 spins initially awarded can go all the way up to 50 spins.  As in the TV show, there are three lifelines and there’s also safety nets at 10 spins and 20 spins ensuring that once you get past the risky first step you can’t lose the entire bonus round.  As the free spins are played with a multiplier that increases with every win, every extra spin won can make a huge difference to potential winnings.

  • Play Fishin’ Frenzy Megaways at Paddy Power Games
    100 No Deposit Spins + Deposit & Play £10, Get Another 100 Free Spins - All Winnings In Cash

    Fishin’ Frenzy Megaways is a pumped up revamp of the classic Blueprint slot from 2014.  The original had just 10 paylines but in the Megaways version, the 6 reels give up to 15,625 ways to win (depending, as always with Megaways, on the number of symbols that land on each reel which varies from spin to spin).  It’s one of the more straightforward Megaways slots out there, without the horizontal reel and exploding symbols of the quintessential Megaways game Bonanza.

    Just as in the original, the fisherman scatter is the key symbol, both for triggering the free spins bonus round and getting big wins once in there; the fish symbols come with price tags representing what you can win in the bonus round if you spin them at the same time as a fisherman.  The game does a great job of combining the look and feel of the original with the thrill of the Megaways mechanic, and in common with many other Megaways slots it has a Buy The Bonus feature whereby a player can pay 100x stake to trigger the bonus round immediately.

    Fishin’ Frenzy Megaways has RTP of 95.02%

  • Play Valletta Megaways at Fun Casino
    Deposit £10+, Get 100% Slot Bonus Up To £123 & 10% Cashback

    Valletta Megaways is another in the series of Megaways games by Blueprint.  It has 6 reels each of which displays up to 5 symbols giving up to 15625 ways to win.  The city of Valletta is the capital of Malta which is a major base for the iGaming industry but the theming harks back to the island’s epic past.

    Valletta Megaways is a Buy The Bonus Round slot.  The Valletta Bet can be bought for 100x stake.  This awards a spin that is guaranteed to produce at least 3 scatters for 10 free spins (but may produce more scatters for higher numbers of free spins).  During the bonus round, the Valletta Streak feature is active.  This is basically sticky wins – on any winning spin, the winning symbols stay in place for a respin and respins continue until no new winning symbols appear.  If all the symbols on the reels become sticky, more free spins are awarded.

    The Valletta Streak feature can also be randomly triggered during the base game and other features randomly add extra scatters of wild to the reels to keep things interesting.

    Valletta Megaways has RTP of 96.45% – or 97% if you do nothing but buy the bonus round (as we suspect many will).

  • Play Genie Jackpots Megaways at Gala Bingo
    Deposit & Play £10, Get £50 Bingo Bonus

    Genie Jackpots Megaways is a sequel to the very popular Genie Jackpots slot by Blueprint, but unlike the original it is not part of the Jackpot King progressive jackpot suite.  Instead, it uses the Megaways game mechanic under license from Big Time Gaming. In Megaways, the symbols vary in height so the number of possible winning combinations across the 6 reels changes with each spin depending on the number of symbols that land on each reel.  In Genie Jackpots Megaways, 2 to 5 symbols can land on a reel – giving 15,625 ways to win if all 6 reels have 5 symbols each. Symbols score the same and count as one symbol only regardless of height.

    Genie Jackpots Megaways has the wealth of bonus features you’d expect from a Blueprint slot game.  There are four bonus features (similar to the bonus features in that Blueprint classic Ted) which can be triggered by any spin plus four different bonus rounds (one of which is selected via the Cave of Wonders pick-me when free spins are triggered by the appearance of 3 or more scatters).  Can’t be bothered to wait for the bonus round?  Depending on where you play Genie Jackpots Megaways you may be able to use the Genie Bonus Wish feature (another Big Time Gaming invention) to trigger the bonus round immediately for 100x stake (some operators do not have this feature enabled).

    * 18+. New online customers only. Min 1st deposit & spend £10 on Bingo tickets = £50 Bingo bonus. Wagering reqs apply: 4x bingo bonus; . Bonus valid for 1 week after credit. T&Cs apply.

  • Play Vikings Unleashed Megaways at Paddy Power Games
    100 No Deposit Spins + Deposit & Play £10, Get Another 100 Free Spins - All Winnings In Cash

    Vikings Unleashed Megaways is one of several games produced by Blueprint using the Megaways mechanic under licence from Big Time Gaming (who invented it).  The base game plays very like Bonanza and what makes it different to many other Megaways slots is the bonus round – or rather the elaborate mechanisms for setting up the bonus round.  There are FOUR different options for buying the bonus round (priced at 25x, 50x, 75x and 100x spin value) and before the bonus round starts the player can gamble to get a better bonus round – one extra spin and one multiplier step at a time.  Gambling successfully all the way up to the maximum of 27 free spins starting with a 10x multiplier can open the way for a very large win indeed, as every cascade win during the bonus round increases the multiplier by 1, but lose a gamble and you lose the entire bonus round.

    Vikings Unleashed Megaways has RTP of 96.5% and can be played from 20p a spin; at that spin value the cheapest buy the bonus round option (5 free spins) is priced at £5.

    * 1) To take part, you must register via the registration code PGCTV1 and opt in. 2) Get SMS-verified by supplying a valid telephone number. 3) Enter the validation code received by SMS to redeem the free spins. 4) Free Spins are valid on any of our Daily Jackpot games. 5) Free Spins will expire in 10 days from receipt of the offer.

  • Play White Rabbit at Casper Games
    Deposit £10+To Open The Ghostly Chest, Top Prize 500 Starburst Spins

    White Rabbit by Big Time Gaming was groundbreaking – the first slot game in which players could go directly to the bonus round by paying 100x stake.

    White Rabbit is a Megaways slot but without the extra horizontal reel seen in Bonanza, Extra Chilli and many others.  The bonus round is also a bit different to usual; instead of an increasing multiplier, there is a special Cupcake symbol that makes the reel it is on increase in height by one symbol for the rest of the free spins.  When a reel reaches the maximum height of 12 symbols, between 3 and 12 extra free spins are awarded and the reel is enhanced with extra high scoring symbols and wilds.  If all reels reach maximum height there are up to 248,832 ways to win.

    The RTP of White Rabbit without buying this potentially very exciting bonus round is 97.24%; buying the bonus round immediately without collecting any BTG coins towards it has a slightly better RTP of 97.77% and as BTG coins are collected, the RTP slowly goes down to 97.24%.  This is a slot where it really is all about buying the bonus round and we suspect a great many players don’t even bother with the base game.

    In October 2019, the UK Gambling Commission moved to ban Bonus Buy slots from the UK.  White Rabbit was temporarily taken offline and returned a couple of weeks later minus the bonus buy button (it’s still possible to collect BTG coins towards the bonus but you have to wait for the price to reach 0 to trigger the bonus round).

  • Play Reel Rush 2 at Lucky VIP Casino
    Deposit £10 - £50, Get 100% Slot Bonus

    Reel Rush 2 by Net Ent is the sequel to the original Reel Rush game from 2013.  Like the original, it has classic platformer video game styling and a distinctive 45 way diamond shaped reels arrangement, with extra positions that are unlocked on respins after every won, increasing the numbers of ways to win up to a maximum of 1875 ways on the fifth respin.  Starting with only one symbol in play on reel 1 (which can’t be a wild), it can be hard to get the string of wins going but there are some random bonus features that help by awarding a re-spin on a loss, turning symbols wild or unlocking extra parts of the play area.  Reel Rush 2 also has a 3125 way Free Spins bonus round (triggered by unlocking the whole of the play area) which turns into Super Free Spins (with a progressive multiplier going up on every win) if the player has collected enough tokens through play, gambles or pays to top them up to the required 2000.

    Basically, this is a buy the bonus round slot – but instead of being able to buy it straight off (which is no longer allowed in the UK), you have to wait for the basic bonus round to be triggered before you can buy the upgrade.

    Reel Rush 2 can be played from 20p a spin and has RTP of 95.53%  – 96.58%; the variable RTP is because there is a slightly higher RTP attached to buying Super Tokens to upgrade the bonus round than to playing it as is or gambling.

    * Min. 1st dep. of £10-£50. Max bonus £50 on selected slots; 30x wagering on the sum of deposit & bonus applies. Max convertible to real is £250. T&C's Apply.

  • Play Extra Chilli at Casino Joy
    Deposit £10 - £200, Get 100% Slot Bonus & 200 Starburst Spins

    Extra Chilli by Big Time Gaming is a Megaways slot which was the first game in which you could not only buy the bonus round (for 50x stake) but also gamble it (repeatedly) to get a better bonus round with an extra 4 free spins – extra spicy indeed!  Megaways slots are quite high variance anyway and the ability to buy and gamble the bonus round sent the variance through the roof.  The UKGC considered this to be too dangerous and the game had to be temporarily removed from the UK market in October 2019.  A month later, it is back but without the buy the bonus round button; you can still collect Big Time Gaming coins towards triggering it.

    If you gamble the bonus round in Extra Chilli and lose, you can return to the base game with no free spins at all which is pretty brutal.  In subsequent games with the gamble the bonus round feature, it was refined so that players could make smaller gambles to increment the free spins one at a time and have a better chance of winning.

    Play Extra Chilli long enough and you may manage to trigger what is admittedly a potentially very exciting bonus round naturally or collect enough BTG coins to start it – if you haven’t lost your shirt, your shoes and the horse you rode in on by then.  Handle with extreme care!

Back in November 2017, Big Time Gaming released a game with a new feature that would change the face of online slots.  That game was White Rabbit and the feature was “Feature DropTM” – aka buying the bonus round.

Big Time Gaming were already well known for producing slots with insane bonus rounds but, as is the way with high variance slots, players were having to wait a long, long time to play them.  White Rabbit short circuited that by providing a means for players to go straight to the bonus round for 100x stake.

In White Rabbit, players could also collect BTG coins during a session of play to reduce the cost of triggering the bonus round (or eventually trigger it immediately), but this part of the feature hasn’t made a reappearance in many of the later releases, probably because everyone who was interested in buying the bonus round would do so at the start of play and not wait to get BTG coins to bring the cost down.

Big Time Gaming weren’t just catering to impatient players by making it possible to buy the bonus round – they were also getting themselves masses of free publicity.  Their earlier games Bonanza and Danger High Voltage had already established the idea of high variance slots as a spectator sport on the Twitch live streaming platform.  Feature Drop meant that the streamers could make things much more exciting for their audience by missing out all that boring waiting for the bonus round – and it also meant that by buying the bonus round multiple times, they could get a REALLY good bonus round to post on YouTube without too much time and effort (just lots of money).  The number of such videos on YouTube now is a testament to the brilliance of the idea.

Big Time Gaming’s next releases Extra Chilli took the idea even further.  In Extra Chilli, not only can a player instantly buy the bonus round, but they can then gamble the bonus round to try and get a better bonus round – not just once, but multiple times all the way from the basic 8 free spins up to 24 free spins.

It wasn’t long before other game providers got on board with the idea – first Blueprint, on several of their games with the Megaways reel array also invented by Big Time Gaming, and then Foxium with The Great Albini (notable because it otherwise doesn’t resemble a BTG slot).

In October 2019 the UK Gambling Commission apparently came to the conclusion that buying the bonus round puts players at risk of becoming problem gamblers and wrote to operators asking them to remove such games from the UK market.  The feature certainly enabled a huge amount of money to be gambled (and potentially lost) in a very short space of time.  Even at the minimum spin value of 20p, the bonus round in Extra Chilli cost £10 to buy and because of the gamble facility, the £10 could be instantly lost and another £10 spent right away; at the top spin value of £40, that’s a huge £2000 that could be lost in less than a minute (making FOBTs look like small potatoes).

The situation for 2020 in the UK is that you can still

  1. Gamble the bonus round (Who Wants To Be A Millionaire)
  2. Collect coins or tokens in game to trigger or buy the bonus round (Kingdoms Rise, modified version of White Rabbit)
  3. Pay to upgrade the bonus round once you’ve triggered it through normal play or coin collection (Reel Rush 2)

What you can no longer do is simply buy the bonus round without playing for a while first as this would open the door to being able to buy multiple bonus rounds in a short space of time and potentially lose lurid amounts of money.  Most of the games concerned are now back – but in special UK versions with the Buy The Bonus button disabled.
