How Important is Bonus Buy Feature for a Player?

The Bonus Buy Feature is a way for players to get into the most profitable parts of games – the bonus rounds.

By knowing how other players within our community have fared in the bonus rounds of these games, you’ll get a sense of whether it makes sense to spend money to enter into the bonus rounds, and also what your chances are of triggering bonus rounds without the bonus buy option.

Ultimately, it comes down to what you’re after as a player.

How Much Does It Cost to Buy a Slot Bonus Round?

This is totally dependent on the bonus buy feature in question and varies greatly – for instance, Dog House Megaways asks for 100x your bet. Sometimes, the price for unlocking the Bonus Buy Feature is dependent on the operator and region. You will need to judge whether it’s worth the price to purchase entry into the bonus rounds.

How is the RTP Influenced by Buying a Bonus Round?

When you buy a bonus round in slots, you are essentially elevating the RTP of the game. RTP stands for Return to Player and refers to the percentage of the total amount bet that is returned to the player over the long term. This stat covers both the main game and the bonus levels. If we were to look exclusively at the bonus rounds, we would notice that the RTP was higher. This is why players often hope to enter into the bonus rounds of games – it’s more profitable.

Tips on How to Use the Bonus Buy Round

Here’s our guide for how you should go about purchasing bonus buys:

  1. Check the cost of the bonus

By clicking on the bonus buys button, you will be told exactly how much you’re paying for free spins. If it is not clear, check the rules of the game. But don’t buy them just yet.

  1. Check the bonus frequency

If a slot has a high bonus frequency, then you might consider not purchasing bonus buys as you might be able to enter the bonus rounds through normal spins.

  1. Analyse how rewarding the bonus round is

Weigh up the average bonus win against the price of bonus buys. Also check your chances of hitting a big win in the main game: look at the game’s hit rate and best win. Consider your finances and budget accordingly before you decide to purchase bonus buys. If you still want to purchase bonus buys, click Buy Free Spins (or whatever is displayed on your current slot’s bonus buys button) and then click OK.

  1. Know when to quit using the feature

Always remember: never chase your losses. If you don’t get the result you were hoping for, stop playing. Online slots should be about entertainment.
