Advent Calendar vs Ball Sort Puzzle

With 25 different games, there’s always something new to try along the way. Each game offers 30 levels. Collect stars, earn awards and unlock characters who join the Christmas world as you progress. Return to your favourite levels whenever you like, or see how far you can go in the endless modes. The original candy game is still here too, as a little extra for returning players.
