In each stage you have 3 sheep. You can select and drag one of them in any direction you want. An important note is that you must pass selected sheep through two other sheep (exposed by dotted line) to perform a correct move. If not, you have made a wrong move and a foal is recorded for you. If number of your foals is exceeded from a specified number, you loose the game. You must carry the sheep to farm's gate to get a score.
You are the winner if you can gain a specified number of scores by carrying sheep to the farm's gate. Note: number of moves is unlimited.
