What a bonus buy is — and what it isn't
Buy Bonus, in English buy feature, is a button in the game's user interface with which the player pays directly for access to free spins or another in-game bonus round instead of waiting for it to trigger via the base game. The price is charged as a one-off purchase, and the round starts immediately.
It is not the same as bonus cash or a casino promotion — it's a built-in feature the developer has added to the game. Our catalog of 58 Medusa- themed games This feature is in 19, and the remaining 34 award the bonus round only by playing it into view. Neither approach is more correct — they are two different ways to build the same game.
Why the buy button exists
The bonus round is usually the part of the game that contains most of the cap and excitement in it. It's rarely and randomly accessed in the base game — often with a few thousandths probability per spin. The buy button removes the wait: it pays directly for that part of the game that many players want to see faster than the base game would offer.
From a studio perspective the buy button is also its own, separate product inside the game. That's why many purchased spins have its own RTP figure, which may differ slightly from the base game's return. This is not a hidden payout — it is a separate figure shown in the game's own information, just like the base game's return.
When a game has a bonus buy, the info panel may show two different return percentages: one for the base game, the other for the bought round. Both are correct numbers, but they describe different things — the base game over the long run and the bought round over the long run, not each other.
RTP and buy feature: two numbers, not one
Our catalog's 19 bonus-buy games The 11 entries also list the RTP range — i.e. the same game can have different base RTP at different casinos. Read this combination carefully: the casino chooses the base-game RTP level, and the RTP of a purchased spin may be calculated for either version. All of this is visible only in the info panel of the casino you are currently playing at.
For example Medusa Dark Ages (Skywind Group) combines bonus buy and an RTP range: base return 96 %, medium–high volatility and a 15 000× cap. Power of Gods Medusa (Wazdan) does the same in a different way — the buy feature there also ties into a Hold and Win respin round, not just free spins.
| Game | Studio | RTP | Volatility | Maximum win |
|---|---|---|---|---|
| Medusa Dark Ages | Skywind Group | 96 % | medium–high | 15,000× |
| Medusa Hot 1 | Hot Rise Games | 96,21 % | high | 7 500× |
| Story of Medusa II | Spinomenal | 96,04 % | not reported | 3 000× |
| Medusa's Stone | Pragmatic Play | 95,54 % | high | 7 000× |
| Riches of Medusa | qora | 96,1 % | high | 1 000× |
| Medusa The Wild Temple | 7777 Gaming | 95,02 % | high | 10 000× |
| Book of Medusa | Spinomenal | not reported | not reported | not reported |
The full 19-game list can be found in the collection Buy Bonus. When a field is marked “not disclosed”, it means the information isn't published in the game's own details — we don't fill the gap with an estimate.
Volatility in buy‑bonus games: majority high
The buy button doesn’t change the nature of the game — it only moves the player directly to the point where that nature is most visible. That’s why it’s no coincidence that of 19 bonus buy games 8 are marked as high-volatility games, three medium and two medium–high. In four volatility is not stated at all, and in two it says “adjustable” (adjusted) — these are Wazdan games in which the player can change the volatility level from the game's settings before a spin.
This distribution is no surprise: the bonus round is typically the part of the game where most of the return and excitement are located, and in high-volatility games this portion is the largest. When a game doesn't have to be "earned" first through the base game, the variance doesn't disappear — it just appears on the very first spin.
In two of our catalogue's bonus-buy games (Power of Gods Medusa and …Extremely Light, both Wazdan) the player can adjust volatility with a slider before a spin. This is a different feature from the bonus buy, and the two work independently — the adjustment doesn't change the buy price, and the buy doesn't change the adjustment.
Buy bonus and bankroll: same rule as in the base game
Because the buy button is a one‑off action rather than a series of small bets, its impact on the budget feels different even if the principle is the same. One purchase click can consume a large part of the night’s bankroll at once — that is not a problem in itself, but it should be factored into the budget beforehand, not after the button has already been pressed.
The practical tip is simple: if your budget would cover, say, ten purchases in an evening, that doesn’t mean ten purchases is a sensible target — it only means you know your ceiling in advance. The rest is the same variance as in any high-volatility game: good and bad nights happen, and a buy button doesn’t remove either possibility. More on setting limits on the page Responsible gambling.
At the partner casino the same game can be run both as a free demo and for real money — including with the bonus buy if the game offers it. The yellow button is an affiliate link that opens in a new tab.
What to check before you hit buy
The buy button is an irreversible press. Before you do it, check these things in the game’s own info panel — not from memory or another site’s review:
- Buy price as a multiple of the stake. It is always visible in the purchase window before confirmation. If you don't see it, don't confirm the purchase.
- Is there a separate RTP for the purchased round. If it is, it may differ from the base game — in either direction.
- Volatility after the spin has started. A buy does not remove variance: the same high-volatility nature applies to a purchased spin as to one triggered in the base game.
- Does the casino have its own restrictions on bonus buys. Some casinos and licensing jurisdictions restrict or disable the purchase feature entirely — this is stated in the casino's own terms, not in the game's information.
- Your budget for this single spin. Because the buy-in is a one-off payment, its cost should be counted as part of your evening budget in advance, not afterwards.
What we don't claim to know
We do not publish a general price table for bonus buys, because the price is not one number but a game-specific setting you see only in the buy window. We also do not claim that bonus buys are statistically more or less profitable — that depends on the game's own buy-mode RTP, which we do not guess when it is not disclosed.
We do not say a bonus buy is a “good time to buy” or that a game is “hot” right now. That information does not exist. The purchase button is always the same button, regardless of what previous spins have shown.
The network partner casino is the only destination we promote — the choice between demo and real money is made on site, the venue's own terms apply.
Short summary
- Buy Bonus is a one-time purchase that grants direct access to the bonus round — not a discount or a casino bonus.
- Of the 58 games in the catalog 19 offers it, and 11 of them also have an RTP range.
- A purchased round can have its own RTP that differs from the base game — both are read from the casino’s own info panel where you play.
- The price isn't published as a general figure because it's game-specific — it is always shown in the purchase window before confirmation.
- Buying does not remove volatility nor change the fact that a slot is entertainment with a known price in advance.
