Like all casino games, slots have to be random, or there’s just no point playing them. The bit of the slots software that produces the randomness is called a random number generator or RNG.

This is because they are pooled across more than one casino – and usually, every single casino that has the game. But if they do say it’s free, then you will not be expected to make a single deposit to get your spins unless clearly stated otherwise.
