Players take turns arranging their cards to make a single digit number, a two digit number, a three digit number and a four digit number. They should do this while the other player is not looking.
The player with the largest single digit number wins one point, the largest two digit number wins two points, the largest three digit number wins three points and the largest four digit number wins four points.
The game can be played many times as strategies are developed and the first player to earn 50 points is the winner.
