How to Enjoy the Frog Race Bet your "En" by predicting which frog will win and by watching the odds. You can bet up to 500 "En" at one time. You may receive a refund based on the displayed odds. Each frog has a different character. Also remember the name of each frog. This is a secret just between you and me: The character of each frog is seen in its action before the race. Frogs may occasionally surprise the stall owner with a super jump.
