Bonus Bet is a slot feature that raises the stake to improve the odds of triggering a bonus round, and it is a separate mechanic from Bonus Buy, which purchases entry into the round outright.
A stake-based mechanic that shifts trigger frequency rather than buying the bonus round directly.
Bonus Bet is a stake-adjustment feature in slot machines that increases the size of a spin's wager in exchange for better odds of triggering the bonus round, most commonly free spins. It is used across several Pragmatic Play titles in this catalogue, and it should not be confused with Bonus Buy, a separate feature that purchases direct entry into the round instead of raising trigger odds over time.
Bonus Bet works by raising the base wager on every spin — commonly by a set percentage — in return for better odds that scatter symbols or another trigger condition will land. Unlike a one-off purchase, the increased stake applies continuously, spin after spin, until the player switches it off. The house edge on the base game is not changed simply because Bonus Bet is active; the mechanic redistributes trigger frequency rather than the underlying return. Other mechanics, such as Stacked Symbols, influence trigger odds differently by clustering symbols on the reel rather than raising the stake.
Bonus Bet raises the stake to improve the odds of a natural trigger, while Bonus Buy is a different feature entirely: it lets the player pay a fixed multiple of the base bet, typically 50x to 200x depending on volatility and payout potential, to enter the bonus round immediately without spinning for it. Ripe Rewards in this catalogue combines both: Bonus Bet raises trigger frequency during normal play, while a separate Bonus Buy option purchases instant entry. Some Pragmatic Play titles extend the purchase idea further with X iter, a tiered menu offering several bonus-buy price points in a single game.
Ante Bet is a related term used by some providers for a mechanic that resembles Bonus Bet — an increased per-spin wager, often 10% to 50% above the base bet, that raises bonus-trigger frequency without buying the round outright. Where a game's information screen labels the feature Ante Bet rather than Bonus Bet, the practical effect is comparable, but the exact figure and terminology vary by studio, so the game's own rules screen remains the only reliable source rather than assuming one name always means the same mechanic.
For illustration, a $1 base bet with a Bonus Buy priced at 100x costs $100 — a figure that sits within the 50x-200x range used across the industry. The RTP applied to a bought round is usually close to the base game's RTP, though some titles run a slightly lower percentage specifically for purchased bonuses, which is why checking the paytable before buying matters more than the sticker price alone.
This catalogue lists Pragmatic Play titles built around the Bonus Bet mechanic. Wild Wild Rage and Mr Tain's Fury: Wild Wild Gladiator each pair Bonus Bet with a Respins-based Hold & Win round, running at high volatility with a maximum win of x4600. Wild Wild Riches and Himalayan Wild pair Bonus Bet with a Cash Collector feature, also at high volatility, with Himalayan Wild carrying the higher ceiling of the two. Ripe Rewards adds a direct Bonus Buy option alongside Bonus Bet, giving players a choice between raising the stake for better odds or paying to enter the round outright.
| Game | RTP | Volatility | Max Win | Feature Combination |
|---|---|---|---|---|
| Wild Wild Rage | 96.77% | High | x4600 | Bonus Bet + Hold & Win |
| Wild Wild Riches | 95% | High | x4608 | Bonus Bet + Cash Collector |
| Himalayan Wild | 95.48% | High | x10000 | Bonus Bet + Cash Collector |
| Ripe Rewards | 96.02% | High | x10000 | Bonus Bet + Bonus Buy |
| Mr Tain's Fury: Wild Wild Gladiator | 96.77% | High | x4600 | Bonus Bet + Hold & Win |
Of this group, Himalayan Wild and Ripe Rewards carry the highest ceiling at x10000, while Ripe Rewards is the only title here that pairs Bonus Bet with a direct Bonus Buy option.
Before switching Bonus Bet on, check the game's information screen for the exact stake increase and the RTP that applies while the feature is active, since providers publish this figure separately from the base RTP when it differs. Volatility matters as much as the multiplier: high-volatility titles concentrate returns into rarer, larger hits, so raising the stake through Bonus Bet increases variance faster than it increases realistic short-term returns. A Progressive Jackpot mechanic works on a different principle again — a pooled prize that grows with wagers across a network — and should not be confused with Bonus Bet's trigger-frequency effect.
Casinos generally require the account balance to cover the elevated per-spin cost, or the full purchase price for Bonus Buy, before the option becomes selectable; a balance below that threshold greys out the feature rather than allowing a partial charge. Because the outcome of a Bonus Bet spin or a Bonus Buy round is generated server-side at the moment of confirmation, a dropped connection immediately after confirming does not cancel the round — the result is already determined and appears in the balance and game history once the connection is restored.
Bonus Buy spins are commonly excluded from bonus wagering requirements or counted at a reduced contribution rate of 10% to 20%, a detail worth checking in the bonus terms before spending deposited bonus funds on a purchase.
Bonus Bet titles from Pragmatic Play appear across a range of operators, and checking licensing and payout terms before playing matters as much as the feature itself. The casino directory lists operators where these titles can be checked for licensing, payment methods and payout terms before a Bonus Bet or Bonus Buy option is used with real funds.
"Bonus Bet changes how often a bonus round arrives, not what it returns over time — treat the higher stake as a variance choice, not a shortcut past the odds."
Bonus Bet suits players who want to influence trigger frequency without committing to a full Bonus Buy price, and who are comfortable with the higher variance that comes from a permanently raised stake. Players on a fixed session budget, or those wary of committing a large sum to a single purchase, may find the standard base game, or simply waiting for a natural trigger, a steadier fit. Checking the specific RTP, stake multiplier and wagering treatment on each title before switching the feature on remains the practical way to use it.

Update history
Bonus Bet raises the wager on every spin to improve the odds of a natural trigger over time, while Bonus Buy is a one-off purchase, typically 50x to 200x the base bet, that enters the bonus round immediately without waiting for a trigger.
Bonus Bet mainly shifts how often the bonus round triggers rather than the game's long-run RTP, which stays close to the base figure; some titles publish a separate RTP for purchased Bonus Buy rounds that runs slightly lower.
Casinos generally require the balance to cover the elevated stake or full purchase price before the option becomes selectable; a balance below that threshold greys out the feature rather than allowing a partial charge.
The UK Gambling Commission banned the Bonus Buy mechanic in June 2026 for UKGC-licensed casinos, citing risks of impulsive, large one-click spending; the feature remains available at operators licensed outside the UK, though regulatory scrutiny is increasing.
Bonus Buy spins are commonly excluded from wagering requirements or counted at a reduced rate of 10% to 20%; the exact treatment depends on the specific casino's bonus terms, so it is worth checking before using deposited bonus funds on a purchase.
