Whether the terms let the operator void a win from bonus money at its own discretion. Everything that decides whether you keep a win is built by the casino, and none of it is visible inside the game window. The money in Mega Moolah went into the progressive jackpot instead of the base game.

Mega Moolah is the world’s largest progressive jackpot, and it has hit on average every 9-10 weeks over the last 20 years.

Twenty two slots on this site have a written review.
