A monkey game is an assured WIN if your answer is CORRECT.
747 monkeys are awesome, and they may occasionally come and visit you. They can't do math, or play cards! All they can think of is bananas - Any question you ask them, their answer is banana.
Since the monkeys never give the right answer, if you give the correct answer, you will ALWAYS WIN the game!
A monkey game will multiply your winning amount from 2 to ANY number of times the game amount, depending on how lucky you are.
A monkey on a chip indicates there are monkeys lurking around on those games. It does not mean all the games are monkey games. Monkeys appear randomly, and you won't know if a game is a monkey game, until they appear on your results screen!
