Mega Joker  99% RTP\n\n Though it's a relatively simple game with just three reels and three rows, Mega Joker is a famous and beloved high-volatility slot thanks largely to its eye-popping 99% RTP, bonus Supermeter game, and progressive jackpot.

It means that the joker is a wild card. A wild card is one that can be substituted for any other card value. It is hence a very powerful card that can be used to complete all kinds of poker hands depending on which card we are missing.
