Buy a bonus – Yes or No? Slots with a buy a bonus feature

Online slots are fun and exciting. But slots can also be very frustrating when you are waiting for a bonus feature or a random feature. Bonus games and random features make slots more exiting. During a bonus game you can normally win more money. You can win up to 10.000 times your bet. Before you can play a bonus game you must trigger it. You have to trigger 3 scatters, 3 bonus symbols or other bonus combinations.

It may take a while before you trigger a bonus. The average trigger percentage is lower than 1%. At NetEnt games the average is 1 bonus game out of 100 spins. Of course you can hit 3 bonus games in 100 spins but you can also hit 1 bonus game in 300 spins. When you play high volatility games the bonus trigger percentage is even lower. It may take up to 500 spins before you trigger a bonus game. This could be very frustrating and expansive. Frustrating because you trigger 2 bonus symbols all the time. At a lot of slots you need to have a lot of patience when you want to play a bonus game.

Since a few months there are a few game providers with a solution. These game providers add a so-called “Buy a Bonus” feature. When you activate this feature you can buy a bonus game for a certain amount of money.

On this page I am going to tell you more about the buy a bonus feature. I am also going to show you a list of games with the buy a bonus feature.

How does a “Buy a bonus” feature work

The Buy a bonus feature is exactly what it says. When you activate this feature you can buy a bonus any time you want. A bonus feature normally costs a multiple of your bet amount. When you have a higher bet amount you have to pay more for the bonus feature. Of course you can win more money when you buy a more expansive bonus feature.

Let’s make things a bit easier with an example. At Videoslots Casino you can play 100+ games with a buy a bonus feature. Extra Chilli (Big Time Gaming) is one of the popular ones. At Extra Chilli you can buy the bonus when you click on the “Feature drop” button. You have to pay 50 times your bet amount when you want to activate the bonus. We play with a €1.00 bet per spin and we have to pay €50 when we want to buy this bonus.

When you activate the bonus you don’t have to spin 3 bonus symbols in the normal game. You get 3 bonus symbols on your next spin after activating the bonus feature. You receive 8 free spins when you hit 3 bonus symbols. With a bit of luck you hit 4 or even 5 bonus symbols with the bonus spin. With 4 symbols you receive 12 free spins and with 5 bonus symbols you receive 16 free spins. More free spins probably help you to win more money during the bonus game.

buy a bonus feature slots how does it work

At Extra Chilli you can buy the bonus feature for 50 times your bet amount


White Rabbit is another interesting game with the buy a bonus feature. In the normal game you have to trigger 3 rabbits when you want to trigger the bonus game. You can trigger 3 rabbits (or more) when you buy the bonus feature for 100x your bet amount. When you play with €0,10 per spin you have to pay €10 to trigger the bonus. When you play White Rabbit we recommend you to buy the bonus because it can take a while before you trigger the bonus in the normal game. The average hit percentage at White rabbit is between 200 and 300 spins.

Big Bets – Feature Drop – High Roller Bet

At online casinos there are a lot of casino games. These games are developed by different game providers. Each game provider has a few games where players can buy a bonus games. They all give it a different name. At Big time Gaming they call it the “Feature Drop”. At iSoftBet they call this feature the High Roller Bets and at WMS and SG games you can buy a Big Bet. Quickspin calls it a High Roller Bonus. At Big Time Gaming and Stakelogic you are able to buy bonuses cheaper when you collect coins during the normal game. Each time you spin a coin the prize of the bonus game decreases. This is a way to lower the prize for the bonus games at a few games (Extra Chilli, Book of Cleopatra and Neon Cluster Pays).

Should I use the “buy a bonus” feature?

We recommend our visitors to buy a bonus when they want to prevent frustration and when they don’t have patience. When you buy a bonus you have the highest chance to win money on a slot machine. Slot machines like Extra Chilli have a payout percentage of 96% or higher. And you have the highest winning chances during a bonus game. In a normal game you can win up to 100 or 200 times your bet amount. But when you activate a bonus feature you can win up to 10.000 or even 20.000 times your bet amount.

Often it is cheaper to buy a bonus feature because you are 100% sure you can play the bonus game. When you try to trigger a bonus game in the normal game it can take a very long time. In most cases the prize of buying a bonus game is cheaper then the spins you need to trigger the bonus in the normal game. Of course you can be a lucky player and hit the bonus in the normal game within a few spins.

That is why we always recommend to play a few spins (maximum 50 spins) before you buy a bonus. Lucky players trigger the bonus or win some money with the first 50 spins. If you didn’t trigger the bonus within 50 spins you should buy the bonus game.

Play responsible and don’t continue buying bonus games at a particular game when your first bonus games are not profitable. You can always switch between games and see if you have more luck at another game where you can buy the bonus.

Dunder Casino – Recommended online casino with “buy a bonus” feature

Of course I want to recommend one of the casinos on our website. When I look at games with a “buy a bonus” feature I have to recommend Dunder Casino or Videoslots. Dunder has my preference because at this casino you receive better bonuses and their bonus terms are better. At Dunder Casino you can play over 50 slots where you can buy a bonus feature. Dunder Casino offers all games of Big Time Gaming (White Rabbit and Extra Chilli), NetEnt, SG Games and Push Gaming. 

New players at Dunder Casino receive 50 free spins on Book of Dead (no deposit needed) and 100% Bonus on top of their first deposit + 50 Dunder free spins. When you deposit €100 you receive €200 in your account. That means you have more budget to buy bonus games. At White Rabbit you could buy 20 bonus games when you play with a €0,10 bet per spin.

Play Responsible when you buy a bonus game

We recommend all our visitors to play at online casinos with money they can miss. When you play at an online casino you can lose money. And when you start buying Bonus games or Big Bets you can lose money super-fast. During a normal game you lose a few cents per spin. But when you start buying bonus games you can lose €10 – €100 per game. Of course you always win some money back when you buy a bonus game but you could hit a few unprofitable bonus games in a row. When you pay €25 per game you can easily lose €200 in half an hour.

We are not sure if the buy a bonus feature is going to be available in the future because it is a big risk for players. Buying a bonus game could cost a lot of money in a relative short period. we are not sure if the gaming commissions and gambling authorities are happy with these bets.

When you decide to buy a bonus we recommend you to buy them at reliable online casinos. At reliable online casinos you are 100% sure that the outcome of bonus games is not manipulated by the casino.

Slots with a “Buy a bonus” feature

We are very happy that there are slots with a buy a bonus feature. It is an easy and quick way to try a bonus. You don’t have to spend a lot of money and time on a game and hope you trigger a bonus game. With this feature you can simply buy it. When you don’t like the bonus game you can leave the game and try another. Big Time Gaming is the first game provider with slots where players can buy a bonus feature. BTG is a very popular game provider and that is why other game providers started to copy the feature in their games.

Underneath I am going to show you game providers and slots where you can buy a bonus, a big bet or a high roller bet.

After dropping the symbols you see how much money you won with the spin.
