Coins are an in-game currency. They're used for several things:

  • buying boosters;
  • buying additional moves while playing levels;
  • refilling lives.

You can receive coins:

  • for beating levels;
  • for completing game days;
  • for restoring areas on the farm;
  • from the in-game characters as a token of their gratitude for your help, or for other achievements;
  • for updating the game;
  • through in-game purchases available for real money.
