Every casino bonus will have a list of games in its description or bonus terms. It means you can’t use casino bonuses for any game you want to play at an online casino. Actually, the casino will suggest possible options.
Plus, some bonuses are game-specific at their very core: free bonus spins will only work with online pokies, and free chips – only with table games. Free cash credits can usually be used for all kinds of games – with it, players buy Roulette chips or bet on a pokie payline just as well.
