Watch them carefully - when one turns black you have to press the Tamas buttons (A, B, or C) to match the circle that has turned black. You must do it quickly - within 0.5 of a second!
Bump - this appears when the Tama is a toddler/child.
Wait until you see the PUSH sign and press button B twice - you are trying to get the black band as large/wide as possible.
Wait and see if you win the round. It's mostly luck - not skill!
Heading game will appear when the Tama is a teen, Slots will appear when the Tama is an adult.
