To play the game, you shuffle the 104 number cards, lay out four cards face-up to start the four rows, then deal ten cards to each player. Each turn, players simultaneously choose and reveal a card from their hand, then add the cards to the rows, with cards being placed in ascending order based on their number; specifically, each card is placed in the row that ends with the highest number that's below the card's number. When the sixth card is placed in a row, the owner of that card claims the other five cards and the sixth card becomes the first card in a new row.
Each card has a point value. After finishing ten rounds, players tally their score and the player with the fewest points wins!
