The feature exists on most modern releases from Pragmatic Play, Nolimit City, Hacksaw Gaming, Push Gaming, and Relax Gaming, with the buy price set to match the long-term expected value of the round it unlocks.

Spinhub – Best Jackpot Bonus Buy Slots

Not in terms of gameplay or design, but in terms of the return to player (RTP) rate. If you're specifically looking for the best bonus buy slots, Red Tiger doesn't come to mind with the exception of one title: Blood Suckers Megaways, and this one even positions itself closer to the 98% percent mark. Yes, Blood Suckers is a NetEnt slot and a good one at that, but in this case Red Tiger was commissioned to develop this title. The good thing about the Red Tiger bonus buy slots is that they are also suitable for gamblers with a small bankroll. Some features can be activated with as little as 3x your bet.

Magic Spins

On the other hand, Blood Suckers Megaways, with a maximum feature drop buy of 1000x your bet, may be just the thing for high roller players. The developer Relax Gaming is a good choice if you are looking for slot machines to pay for a bonus. Many of the games reach the 97% RTP mark. In the case of the well-known Money Train slot series, it is even an astonishing 98% for the feature buy. Dead Man's Trail is another good one, but see for yourself in the list below. The fortune teller theme is generic for Pragmatic, but the multiplier mechanic during free spins gave the slot a payout profile that has kept it in active rotation across UK lobbies since release. Released by Pragmatic Play in 2020, Madame Destiny Megaways runs on a 6-reel structure with up to 117,649 ways to win. The slot uses tumbling reels during base play and free spins — winning symbols are removed and replaced by new ones falling from above. Three or more scatter symbols cas casino bonus codes free spins trigger 15 free spins, during which a multiplier counter starts at 2x and climbs by 1x with every winning tumble. The multiplier persists across the round and resets between triggers. International markets price the bonus buy at 100x stake. Published RTP is 96.50%, max win is 10,000x stake, and volatility is high. The slot sits within the wider megaways slots family. For UK players, natural trigger frequency runs around one bonus per 200 to 280 spins.

Pragmatic Play's The Hand of Midas applies a money-symbol collection mechanic to a Greek mythology theme. The slot's central feature is a hand wild that collects fixed cash values from money symbols during free spins, producing a structure similar to the Big Bass series but with higher-paying base symbol values and a smaller maximum win cap. Released in 2021 by Pragmatic Play, The Hand of Midas runs on a 5x4 grid with 50 paylines. Money symbols carrying fixed cash values between 1x and 100x stake can land at any time. Three or more scatter symbols trigger 12 free spins, during which gold hand wilds appear at random positions and collect the cash values of any money symbols on the reels. Two more scatters retrigger four additional spins, with each retrigger adding a 1x increment to a global multiplier applied to all collected values for the round.

For UK players, the slot is among the more accessible Bonus Buy Slots in this list because of its lower maximum win ceiling and corresponding shorter trigger gaps. Natural triggers occur every 150 to 220 spins on average, and multiple gold hand collection events per round mean most bonus rounds produce moderate returns rather than the binary outcomes typical of higher-volatility releases.

Should I Consider The Ante Bet Option Over A Feature Buy?

Considering the many options available in No Limit City or Hacksaw games, this is a little uninspiring (as are the RTPs), but it's not a deal breaker! Quickspin, which in our opinion is not so well known for feature drop games, also has some good titles. Some great examples are Sticky Bandits, Wild Luchador and Big Bad Wolf Megaways, although the latter certainly gets its reputation from the original (with its RTP of 97.34%). Speaking of RTP, similar to No Limit City, Quickspin slots are more generous in terms of their bonus buy RTP (again, in relation to the RTP of the base game). The games are generally more straightforward and so are the buy-in options.

3. Dead Canary – Nolimit City

Simply purchase the free spins and off you go (a bit like BTG and Pragmatic)! There is generally nothing fancy here in terms of chance buy. Nevertheless, even with Quickspin games you can buy in at a high price. A bonus buy costs between 50x and 1600x your bet. Red Tiger bonus buy slots are a little monotonous. Pragmatic Play's Buffalo King Megaways is the Megaways adaptation of the original Buffalo King and one of the studio's higher-volatility entries that uses the bonus buy mechanic. The Wild West theme runs throughout the Pragmatic catalogue, but Buffalo King Megaways stands out for combining tumbling reels, a growing free spins multiplier, and one of the highest base ways counts available in the format. Released in 2020 by Pragmatic Play, Buffalo King Megaways runs on a 6-reel Megaways structure with up to 200,704 ways to win. The slot uses tumbling reels during both base game and free spins, with winning symbols removed and replaced. Three or more scatter symbols trigger 15 free spins, with four awarding 18 spins and five awarding 20. During the round, an unlimited multiplier counter increases by 1x with every winning tumble and resets only at round end. Published RTP is 96.52%, max win is 5,000x stake, and volatility is high. For UK players, the slot's natural trigger frequency sits at around one bonus per 200 to 300 spins.

This guide covers six slots best known for their bonus buy mechanics, how those mechanics work in international markets, what UK players experience instead through natural triggers, and four UKGC-licensed casinos where the games are available with the buy feature correctly disabled. Money Train 4 is the most recognisable Bonus Buy Slot on UK-licensed sites and the entry most often cited as the modern benchmark for the format. Relax Gaming's series has progressed through four releases since 2020, with each entry adding more layers to the persistent symbol mechanics that defined the original. Released by Relax Gaming in 2024, Money Train 4 runs on a 6x6 grid that can expand vertically.

Other Honourable Mentions

The slot uses cluster-style scoring during base play and switches to persistent symbol mechanics during free spins, where money symbols, special symbols (collectors, payers, multiplier wilds, persistents), and respins drive long-term return. International markets price the bonus buy from around 100x stake for standard entry up to higher tiers for extended free spins. Three or more scatter symbols trigger the bonus through natural play. Published RTP is 96.10%, max win is 150,000x stake, and volatility sits at the extreme end. The cluster mechanic shares structural ideas with the broader cascading reels slotsfamily.
