Best Slots With Bonus Buy Feature 2026
Slot (Provider) | Bonus Buy Cost | Details and Bonus Mechanics |
Gates of Olympus (Pragmatic Play) | 100x your stake | You get 15 free spins right away. The main feature is random multiplier symbols (from 2x to 500x) that can land anywhere. All multipliers that land are added together and applied to the total win for that spin. If 3+ scatters land during the bonus, you get +5 free spins. |
Sweet Bonanza (Pragmatic Play) | 100x your stake | The bonus round gives you 10 free spins. The mechanic is similar to Gates of Olympus: bomb symbols with multipliers (up to 100x) appear on the reels, and if they land together with a winning combination, their values are added together and applied to the win. |
Mental (Nolimit City) | 120x your stake | A slot with extreme volatility. The bonus game uses xWays and xNudge mechanics, which can exponentially increase the number of symbols and multipliers on the reels. That means the bonus can either pay huge or drain your balance fast. According to player feedback, 73% of Bonus Buy purchases returned less than the cost. |
Tombstone (Nolimit City) | 95x your stake | You can choose from several bonus rounds: Justice Spins, Gunslinger Spins, and Bounty Spins. There’s also the Nolimit Booster, which for an extra fee (2x your stake) guarantees a bonus symbol on the second reel. One review mentions a buy cost of 70x, as well as a 3000x option to guarantee the maximum win. |
San Quentin (Nolimit City) | 100x / 400x / 2000x your stake | This slot has multiple Bonus Buy options. You can pay 100x for 3 bonus symbols, 400x for 4, or 2000x for 5 symbols. The more symbols you buy, the higher your starting potential in the Lockdown Spins round. The slot is known for its xWays mechanic and a massive max win (up to 150,000x), plus a boosted RTP when you buy the bonus (up to 96.95%) |
The Dog House Megaways (Pragmatic Play) | 100x your stake | When you buy the bonus, you get free spins and must choose one of two modes: Sticky Wilds (sticky wilds that stay in place, but fewer spins) or Raining Wilds (more spins, with wilds dropping onto the reels at random). This lets you tailor the bonus to your play style. |
777 Fruity Coins (3 Oaks) | Standard price (around 100x) | What makes it unique is that there are four Bonus Buy options. They differ in the starting number of Collect symbols (one or three) and the bonus type (Bonus or Super Bonus). In the Super Bonus, token values can range from 10x to 1000x, which affects the starting potential of the game. |
Important Things to Know About Bonus Buys
- Cost and risk: Bonus Buy prices usually range from 50x to 200x your stake. But can reach 2000x (as in San Quentin) or even 3000x in extreme-volatility slots. Buying is trading a long wait for high short-term risk.
- RTP and expected value: The return to player (RTP) when buying a bonus is generally the same or almost the same as in the base game. That means over the long run the casino still has the edge, and buying a bonus is no guarantee of a win.
- Strategy: Bonus Buys suit players who want to jump straight into the high-volatility part of the game and are willing to risk a significant amount for a shot at a big win.
What Are Bonus Buy Slots?
Bonus Buy slots are slot machines where you don’t have to wait for scatters to land naturally-you can simply buy the bonus round for a fixed price. That price is usually shown as a multiplier of your stake: for example, 100x means that at a €1 stake, the bonus buy will cost you €100. Once you pay, free spins or a special bonus mode with higher potential start instantly — but there’s still no guarantee of a win.
Activation: In the slot’s interface, a special button appears — “Buy Bonus,” “Bonus Buy,” or “Buy Bonus.” It’s usually located next to the spin button.Cost calculation: The purchase price isn’t fixed in cash; it’s calculated as a multiplier of your current stake per spin. For example, if you’re playing at a €1 stake and the bonus cost is listed as 100x, the purchase will cost you €100. Typical price ranges are from 50x to 200x, but can reach 2000x and higher in high-volatility slots.Deduction and launch: After pressing the button and confirming, the bonus cost is instantly deducted from your balance. The bonus round (usually free spins) starts immediately, and you skip the base game.
Types of slot bonus buys
Bonus Type | How It Works | Examples and Cost |
Standard Fixed Bonus | The most common type. You pay one fixed price and instantly get access to a standard bonus round (usually free spins). The mechanic is simple and predictable: you pay, you get the bonus. | Gates of Olympus (Pragmatic Play): 100x your stake for 15 free spins with additive multipliers. Sweet Bonanza (Pragmatic Play): 100x for 10 free spins with bomb multipliers |
Bonus With Multiple Options to Choose From (Tiered Bonus Buy) | Instead of one option, the slot offers several bonus tiers at different prices. Each next, more expensive tier usually includes more free spins, higher multipliers, or better starting conditions. | San Quentin (Nolimit City): 100x / 400x / 2000x — the more expensive the purchase, the more starting bonus symbols you get. 777 Fruity Coins (3 Oaks): 4 Bonus Buy options that differ in the starting number of Collect symbols (1 or 3 |
Bonus With Extra Options | You buy the bonus and can add one or several paid options that improve the bonus round: guaranteed multipliers, extra symbols, jackpots, etc. | Tiger of Fortune (Evoplay): you can buy the bonus with a choice of one, two, or all three boosters. Rhino Coins (Playson): 6 purchase options, including a Super Bonus with guaranteed jackpots and extra multipliers |
Guaranteed Bonus / Instant Feature | The purchase guarantees not just entry into the bonus, but a specific outcome: a certain symbol landing, Hold & Spin activation, or a jackpot. This reduces the risk of a completely dead bonus. | Coin Trio Piggy Burst (Aristocrat): Instant Feature for ~60x your stake guarantees a Hold & Spin bonus with coins and one upgrade. Rhino Coins (Playson): Super Bonus modes with guaranteed jackpots. |
What Exactly You Can Buy: Types of Bonus Rounds
- Free Spins: The classic and most common option. You get a fixed number of free spins, often with special multipliers or sticky wilds.
- Bonus With Expanding Reels: During the bonus, the number of symbols on the reels can increase, creating more paylines and potential for a big win
- Bonus With Enhanced Multipliers: The purchase activates a round in which all wins are multiplied by a higher coefficient.

- RTP when buying. In some slots, the RTP of the bonus buy is slightly higher than in the base game (for example, up to 96.95% in San Quentin), but this does not guarantee profit over the short term.

How Much Does It Cost to Purchase a Bonus?
The cost of buying a bonus game (Bonus Buy) isn’t a random number-it’s the result of a complex mathematical calculation that takes into account potential winnings, risk, and the casino’s margin. Understanding these factors helps you make more informed decisions.The price of a bonus is based on several key game parameters.Slot volatility: This is the main factor. In high-volatility slots (like those from Nolimit City), wins happen less often but can be very large. To compensate for that risk, the bonus buy price is set higher.
Bonus type and content: The cost directly depends on what you get. The more free spins, the higher the multipliers, the more special symbols (sticky wilds, Collect symbols), and the more complex the mechanic, the more expensive the bonus will be.Number of tiers (options): Some slots offer not one but several bonus options at different prices. For example, you can buy a standard bonus for 80x, a “super bonus” for 150x, and a “mega bonus” for 250x. Each next tier usually includes more spins or higher multipliers.RTP (return to player): This is the theoretical percentage of all stakes that the game returns to players over the long run. Developers set the bonus price so that the game’s built-in RTP is maintained. The difference between the bonus price and its average expected win is the casino’s margin.
Average Prices by Top Providers
- Pragmatic Play.50x-100x your stake.A pioneer of the feature. The standard price is most often 100x for 10–15 free spins. Great for getting familiar with the mechanic
- Nolimit City.95x-2000x+ your stake.Known for extreme volatility and complex mechanics (xWays, xNudge). Offers several bonus tiers, and the price can be very high
- Hacksaw Gaming.80x-400x your stake. Another high-volatility provider. Often offers a choice of two bonuses at different prices (e.g., 110x and 200x for different versions).
Bonus Buy Strategies and Tips
Playing slots with a bonus buy isn’t about finding a “secret button”-it’s about risk management and discipline. Below are the key strategies and personal tips to help you play with a clear head.
- Strict Bankroll Management.This is the foundation — without it, the other tips won’t work. Buying a bonus isn’t one bet; it’s several at once, so the cost of a mistake rises sharply.The 5–10% rule: Never spend more than 5–10% of your total session bankroll on a single bonus buy. If you have $1,000, one purchase shouldn’t cost more than $50–100.Separate budget: Create a separate budget specifically for bonus buys. This isn’t money for your main game — it’s money you’re prepared to lose entirely.Limit on purchases: Decide in advance how many times you can buy a bonus in a session. For example, no more than 2–3 times. If you’re down after two purchases stop-don’t try to win it back.
- Psychology and Impulse Control.Bonus buy slots are designed to trigger impulsive decisions. Your job is to resist that.Don’t chase losses: The most dangerous thought is “I’ll just buy one more bonus and win it all back.” That’s a classic trap. After a bad purchase, take a break — don’t make another purchase.
Set a stop-loss: Decide on an amount that, once reached, means you immediately end the session. For example, if you lose 30% of your bankroll, close the slot.Don’t buy bonuses on tilt: If you’re frustrated by a loss or tired, the odds of making a bad decision skyrocket. Buying a bonus in a bad mood with a thin bankroll is a fast track to blowing your balance. - Choosing the Slot: What to Look At Before Buying.Not all slots are equally good for bonus buys. Some parameters can dramatically change your odds.Check the RTP when buying: In some slots, the bonus buy RTP differs from the base game RTP. For example, in Money Train 2, the base RTP is 96.4%, but when buying the bonus it’s 98%. That’s worth noting.Beware the “high RTP trap”: If you see a bonus buy RTP of 97%+ on a slot priced at 100x, it may be a marketing move. A higher RTP on an expensive bet changes not just the potential return but also what you’re risking in one click.Study the bonus structure: Before you pay, look at the slot info to see what the bonus actually gives you. Does it have sticky wilds, expanding symbols, or growing multipliers? The clearer the mechanic, the fewer surprises.
