Zero wouldn't be fun. You need to allow people to win, just not over time. Slots is a random series of losing, small wins, bigger wins, and very occasionally big bonus rounds (every ~100-200 spins) which is the dopamine hit. The key is that over time, the losing needs to happen more often than the winning.
