The object of the game is to have the least number of flies once all of the rubbish has been put in the bin.
Switch on the bin, and it will start to vibrate. They timing changes every so often and the flies jump out when you lift the lid but no one knows when. The first player lifts the lid and tries to place a piece of rubbish inside. If a fly jumps out then that player has to keep it.
Close the lid properly at the end of each turn and the next player goes.
The game is over when all the rubbish pieces have been placed inside the bin. Players then count the number of flies they have, the winner is the player with the least number of flies.
