?The Sensei calls the Ninjas to practice, but these are no ordinary fighters. Each Ninja carries a sand timer and it's your job to make sure that the sand keeps running. Turn a card, move the right Ninja from one zone to another, until the Sensei card orders another player to continue. If you can keep the Ninjas turning and the sand running in the timers until your turn is over, you can collect a Ninja star! The player who collects five Ninja stars first, wind the game!
