The goal of the game is for the team to complete the grid before any player runs out of available actions. Cards must be placed so that the grid ascends in numerical order from bottom left to top right. All the players win if they manage to complete the grid and have placed a Start and Finish card. All players lose if a single player can no longer play or discard any cards legally following the instructions given below. The players may not, however, communicate.
Play is taken in turns moving clockwise with the quietest player going first. On a player’s turn they must do one of the following: 1. Play a card or 2. Discard two cards. Then they must draw back up to a hand of five cards. Cards must be placed so that the grid ascends in numerical order from bottom left to top right. If the card is placed next to an existing card in the sequence then they must discard cards from their hand equal to the difference between the numbers face down in front of them e.g. placing a 5 next to a 3 will require two cards to be discarded from their hand. This applies even if the cards are on different rows.
