Bonus Buy Slots in Estonia 2026: How Feature Buy Works and Its Cost

Bonus buy slots let you skip the wait for the bonus round. You pay a fixed price and the free spins start straight away. That price is a multiple of your bet, most often around 100 times the stake, so a €0.20 bet means a €20 purchase and a €1 bet means a €100 purchase. Feature buy is expensive and swings hard: a single purchase can return only a small part of what you paid for it.

If you have seen the buy button on a slot and want to know what it costs before pressing it, start here. We calculate how many purchases fit into a €100 balance, compare buying with regular spinning and explain why an active bonus and the buy feature clash. Budget rules and five casinos licensed by the Estonian Tax and Customs Board (EMTA) follow. For a wider comparison of slot sites, see our page on online slots casinos.

What bonus buy means in a slot

In a regular slot the bonus round triggers when enough scatter symbols land on the reels. A bonus buy (also called feature buy or buy bonus) removes the waiting: you pay the price, the game sends you into the bonus round at once, and you usually get free spins with the game's special rules attached.

Buy bonus slots are most common among high-volatility games. Studios such as Pragmatic Play, Nolimit City, Hacksaw Gaming and Relax Gaming use the feature often. Sweet Bonanza is a well-known Pragmatic example, and Wanted Dead or a Wild is one from Hacksaw Gaming. More on these studios in our piece on Pragmatic Play slots and the overview of Megaways and other popular slot games.

The round you buy is the same one scatters would give you. Some games offer a second, pricier option with an extra edge, such as more spins or a higher starting multiplier.

How feature buy works, step by step

1. Open the slot and set your bet first. The purchase price is calculated from that bet, so the same bonus round costs ten times more at €1 than at €0.10.
2. Press the buy button. It usually sits next to the reels and is labelled “Buy Bonus” or “Buy Feature”.
3. Read the price in euros in the purchase window. Each buy option has its own price.
4. Confirm the purchase. The amount leaves your balance immediately and cannot be reversed, even if the round pays nothing.
5. The game plays out the bonus round. Some slots let you pick a bonus type first.
6. When the round ends, the win is added to your balance. Compare what came back with the price you paid, and only then decide whether to carry on.

That last step matters most. If you look only at the win and forget the price, a €15 win feels good even though it cost you €20.

Bonus buy slots: what one purchase costs

The price is shown as a multiple of your bet. Around 100x is the usual level, though some games charge noticeably less and others several times more. The table below uses a 100x price to keep the maths simple and shows how quickly purchases use up a balance.

The table is plain arithmetic and predicts no results. Still, at a €0.20 bet, €100 buys five attempts, against 500 spins and several hours in normal play. That is how a €100 balance can vanish within minutes when you buy bonuses.

Work backwards before you buy. Decide how large a single purchase may be and divide that figure by the price multiplier. With a €20 limit per purchase and a 100x price, your bet is €0.20. In a game with a higher multiplier, lower the bet to match.

Regular play compared with a bonus buy

In regular play you also pay for the bonus round, in instalments: every spin that misses it is part of the price. A bonus buy shows that price openly and charges it at once. If you choose to buy, accept that several purchases in a row may each return less than they cost.

RTP and volatility when you buy the bonus

RTP (return to player) shows what share of all stakes a game pays back in theory over a very long run. The RTP of the buy feature can differ from the slot's figure in regular play. The gap is usually small and depends on the game; the correct number sits on the info or help screen, often behind a question mark icon. If RTP drives your choice, start with our list of high RTP casinos, and for background read which casinos offer the best RTP.

A theoretical RTP does not shield you from swings in a short session, and volatility in buy feature slots is high. Most purchases return less than their price, while a win of several times the cost comes less often. A run of purchases that all finish under the price is normal here.

A made-up example: a player makes five €20 purchases at a €0.20 bet, spending €100 in total. The bonus rounds return €6, €14, €9, €3 and €52, which adds up to €84. One round paid more than double its price, yet the session still ended €16 down. If rare big wins are what draws you, jackpot casinos are another type of play with a similarly high risk profile.

Bonus money and feature buy

If you have an active welcome bonus or another offer whose wagering requirement is still open, many casinos ban or restrict buying the bonus round under their rules. The reasoning is simple: a purchase lets you stake a large amount in a single action. Some casinos lock the button; others only state the ban in the terms.

Before your first purchase, read the bonus terms on excluded games and features. Breaking them can cost you the bonus and any winnings made with it. If you plan to play with the buy feature, it is easier to deposit without activating a bonus or to finish your current wagering before you press the button.

Budget rules for buying bonuses

We suggest these rules for feature buy slots. They keep spending inside a limit you set in advance.

• Keep one purchase at no more than 10% of the session budget. With €100 for the session, the cap is a €10 purchase, which is a €0.10 bet in a game with a 100x price.
• Fix the number of purchases before you start, for example five, and stop there even if the last round paid well.
• Do not raise the bet after a loss. A bigger bet means a bigger price, and the loss grows faster.
• Set a deposit limit on your casino account before the first purchase.
• When your balance is above the starting amount, withdraw part of the win before buying again.
• Check the price each time you switch game or bet, as the multiplier varies between games.

A monthly example: if you have decided that €200 a month can go on entertainment, the 10% rule caps a single purchase at €20. In that case a €0.20 bet in a game with a 100x price sits right on the limit, and a €0.50 bet is already over it.

What to consider in 2026

Online casino play in Estonia is open to people aged 21 and over. Winnings from an EMTA-licensed casino are tax free, and the same goes for casinos licensed elsewhere in the European Economic Area. Winnings from a casino licensed outside the EEA may be subject to 22% income tax, so check your own situation with EMTA. The buy button may be switched off in some games and at some casinos, so check in the game itself.

Rules differ from country to country too. In the United Kingdom, for example, the Gambling Commission banned the bonus buy feature. Providers may therefore ship the same slot in different forms per market. Check the price and RTP on the info screen yourself, since forums and videos may describe another market's version.

Responsible gambling

Buying bonuses speeds up play, and fast play burns through money faster. If you notice you are buying one round after another to win back a loss, take a break and review your deposit limits. Through EMTA you can register a gambling restriction (hasartmängukeeld) that shuts you out of Estonian-licensed casinos. Free advice is available from the Gambling Addiction Counselling Centre (Hasartmängusõltuvuse Nõustamiskeskus) on 15410 and at 15410.ee.
