Stars are the main currency in Color Switch. They are found approximately in every game mode
The Player can earn stars by playing Game mode Levels or Endless Modes. Sometimes an uncommon star might appear that is worth 10 stars. Playing the Daily Challenge will earn the player 50 Stars or by spinning the wheel in the Daily Prize at where the player can get 10, 25, 50 or 99 Stars. There is an option to buy (using real life currency) a "Double Stars" worth $2.99. This will double the stars the player earned whether its a fail or win. Another way to earn stars is by watching an ad after failing or winning a level at where it will give 30 Stars.
The only use of the Stars is to purchase some skins for the ball.
