Shuffle the deck and deal each player ten cards. The players keep their cards secret and they should arrange them numerically. Four cards are taken from the deck and placed face up on the table. Each of the four cards is the first card in a row. Each row may never contain more than 5 cards.
All players choose one of the cards from their hand and place it face down before themselves.
They are revealed at the same time. Whoever played the lowest card goes first. That player places his card into one of the four rows, then the player who played the next higher card places his card into one of the four rows etc. until all players have placed their chosen cards. The cards are always placed in a row side by side. This process is repeated until all players have played their 10 cards.
