A bonus buy slot machine is the solution offered when you no longer want to wait for the triggering of the free spins bonus. How does it work? In traditional slot machines, bonuses are often activated by the appearance of a specific symbol, the Scatter. It is this symbol that takes you to the heart of the machine, towards the free spins.

With the bonus buy option, you can bypass this waiting time by paying a predefined amount to immediately activate the bonus. Generally, the cost ranges between 50 and 100 times the base bet.

This rule is general; it all depends on the machine and the choice of the developer. It is the developer and them alone who decides the amount of the bonus purchase; online casinos have no recourse; they must adhere to pre-registered functions without the possibility of changing them.

Some slots offer bonuses called Bounty Bonuses that can be very expensive, sometimes up to 2,000 times the base spin bet. In this case, the potential gain matches the investment, up to €150,000 on certain machines.
