Scratch is a dexterity/skill game with a hint of strategy, for 1 to 5 players. The aim of the game is to score points by getting your fleas to jump onto Scratch the dog. You do this by skimming cards through the air to try to land on Scratch's card. The fleas each have different abilities which can affect the points scored and there are other card types which also effect the game. All the rules are on the cards themselves.
