What bonus buy slots are

A bonus buy game lets you pay a fixed multiple of your stake to enter the free spins round immediately instead of waiting for scatters to land.

How bonus buy slots work

The buy price is usually 60× to 100× the stake, and the round you get is the same one scatters would have triggered. Buying does not improve the maths — the price is set from the feature's average return, so over enough spins it lands in the same place. In demo mode the buy costs virtual credits, which makes this the one place you can see what 100 bonus rounds actually look like. Buy features are prohibited at UKGC-licensed casinos, so British players usually meet them here first.
