1. Tap the tail of the wooden horse to remove it. Tilt the phone to the left so that 3 soldiers will slide out.
2. Pick up the sword that the third soldier is holding. Use the sword to cut the ropes rapped around the wheels. Now tilt the phone to the right until the soldiers are back inside and the horse slides away from the screen.
3. And once again you've cleared the level, and you can play the next one.
