Bonus Buy Slots: How to Play and Top 7 Slots List

Bonus buy slots let you pay a fixed price to jump straight into a slot’s bonus round, rather than spinning for a natural trigger that may never come. This guide explains how the feature works, walks through a cost example, and gives a bonus buy slots list of seven top titles with provider-verified figures.

What Is a Bonus Buy Slot?

A bonus buy slot is any game with a button, often labelled Buy Bonus, Feature Buy, or Feature Drop, that buys direct entry to the bonus round for a set multiple of your stake. The price is fixed and shown before you commit. The feature is the same one you could trigger normally; you are paying for guaranteed, immediate access, not a different or better round.

How Bonus Rounds Normally Trigger

Without a buy, a bonus round is triggered by landing a set number of scatter symbols, typically three or more, in one spin. Because scatters appear at random, this can happen on your first spin or after several hundred. Free spins are where slots concentrate their multipliers, wild symbol features and biggest payouts, which is why the wait feels long, and the buy exists.

Why Not Every Slot Offers a Bonus Buy

Two reasons keep it off many games. First, regulation: the bonus buy is banned in some markets, including the UK, where the Gambling Commission removed it in 2019 over concerns about fast, high-cost play. Second, design: not every studio builds one in, and classic slots often have no feature worth buying. Where available, it depends on your jurisdiction and operator.

How Bonus Buy Slots Work — A Simple Example

The cost is tied to your base bet, not a flat cash figure. Take a game with a standard 100x buy, the most common price. At a C$0.50 base bet, the bonus costs C$50; raise the base bet to C$1, and it costs C$100. The multiplier stays fixed at 100x; only the cash figure changes.

The price scales fast: that same “100x buy” becomes C$200 at a C$2 stake. The buy is a fixed bet multiplier, so check what your base bet turns it into first. Trying bonus buy slots in free demo mode is the safest way to see how a feature plays, and buying never changes the odds, only how quickly you reach the feature.

How to Buy a Bonus Round Step by Step

The process is similar across providers. Set your base bet first, since this sets the buy price. Find the Buy Bonus or Feature Buy button, usually beside the reels, and click it to open the buy menu, which shows the exact cost and, on some games, a selection of features at different prices. Confirm, and the bonus begins immediately with your guaranteed scatters in place, with any winnings added to your balance afterwards.

Bonus Buy vs Triggering Free Spins Naturally

The trade-off is cost against certainty. Buying guarantees the feature at once and removes the long wait, which suits players who mainly enjoy the bonus round. The downside is a large outlay every time, and a run of poor features drains a bankroll quickly.

Triggering naturally costs only your normal spins and lets a session last far longer, though the trigger may take hundreds of spins or not arrive at all. On most slots, the bonus RTP of a bought feature matches or nearly matches the standard RTP, so buying does not improve long-term value; it changes the shape and speed of play.

Top 7 Bonus Buy Slots at a Glance

The seven slots below are among the best bonus slots from leading providers. Every figure comes from the game provider, though RTP can be configured lower by individual operators, so always confirm the figures inside the game.

A higher RTP points to better long-term value, while volatility tells you how wins arrive: extreme-volatility titles pay rarely but enormously, which is why the 150,000x slots carry the steepest variance. Mechanics differ too, from cluster pays grids to respins-driven bonuses. The best slot depends on bankroll and risk appetite, not the biggest number.

Gates of Olympus (Pragmatic Play) is the natural starting point: the 100x buy guarantees four scatters into free spins with a climbing persistent multiplier. Money Train 4 (Relax Gaming) is the heavyweight, with its Money Cart bonus packed with persistent symbols and a 150,000x ceiling. Wanted Dead or a Wild (Hacksaw Gaming) spreads risk across three features, so the cost varies with your choice.

San Quentin xWays (Nolimit City) is the extreme option, with its top buy costing 2,000x for the best shot at 150,000x. White Rabbit Megaways (Big Time Gaming) has the highest RTP at 97.24%, with its Feature Drop price falling as symbols land. Sugar Rush (Pragmatic Play) is a cluster-pays favourite with 7×7 multiplier spots, and Hand of Anubis (Hacksaw Gaming) closes with Soul Orb multipliers and a premium bonus via a 129x to 200x buy.

Common Bonus Buy Mistakes

The most expensive mistake is repeatedly buying to chase a loss: each purchase comes at a high fixed cost, so weak features drain a bankroll far faster than base-game spins, and buying again to “win it back” only accelerates it. A second error is ignoring how the base bet scales the price, so an affordable buy becomes punishing at a higher stake.

Others include assuming a bought feature pays better than a natural one, when the bonus RTP is identical in most cases, and buying on a slot whose maximum win needs a rare feature tier you did not purchase. Above all, treating the buy as a shortcut to profit, rather than a faster, costlier way to play, is what catches most people out.

Responsible Play Tips for Bonus Buy Slots

Sound bankroll management matters more with bonus buys than with almost any feature, because each click is a large, deliberate spend. Set a firm budget, decide how many buys it allows, and stop when you reach that number regardless of the outcome.

Use free demo mode on bonus buy slots first to see how a feature behaves, and keep individual buys small relative to your budget so one cold run cannot end your session. Never buy to recover a loss, and remember no purchase changes the odds in your favour. Gambling should be entertainment, never a way to make money. Players must be of legal age, and if gambling stops being fun, take a break.

Responsible Gambling

Betting should be entertainment, not a way to make money. Gambling can be addictive—only bet what you can afford to lose, and never chase your losses. Set deposit, loss, and time limits before you play, and take regular breaks.

If gambling stops being fun or starts affecting your finances, relationships, or wellbeing, seek help immediately.
