The bonuses in a slot game appear on the side of the screen. They can have different titles, but usually, they are called buyable features. For a sum of in-game money, you can get a variety of benefits, such as a number of spins in the machine’s free spins round.
You may also receive bonuses for assembling a rare combination of symbols in a slot game. Then you are given a number of free spins and an option to select a symbol that you want to use for the free spins. All the wins you get from the free spins are credited to your account, and you do not wager any additional money.
