A full power bar helps a little but you need your tama to be fat to win at the bump game. 50 pounds and your tamagotchi should do really good, but don't give him too many snacks or your tama will get a toothache
its actually really good. Get your tama to 90lbs and u win rounds like crazy but u still have to get the bar on the other side. Avtually once the bar was so small but i still won!
