Every microgame has a different concept. The duration is always one minute and the maximum score for each is 100.

For some microgames you need to tap the screen , while for others you need to move the phone . Most microgames are additive <+> meaning for each circle you get the score increases, some are subtractive <-> and for each circle you get hit with the score decreases.

There are five different types of circles:
Yellow: huge, slowest, worth 1 point
Green: big, slow, worth 2 points
Blue: medium, average, worth 3 points
Red: small, fast, worth 4 points
Pink: tiny, fastest, worth 5 points
