Slide

The challenge of Slide is to rid yourself of cards to leave as few points as possible.

To set up, deal sixteen cards to each player, who arranges them in a face-down 4x4 grid. Cards range from 1 to 10, with ten copies of each number.

To start, each player reveals a card of their choice from the grid. Starting with whoever revealed the lowest number, each player claims a revealed card and slides it into their grid to close the gap they created when they removed a card.

The starting player keeps rotating clockwise as players do this fifteen more times, eventually having a fully face-up 4x4 grid. Each number in a grid that's adjacent to the same number is removed, and the sum of the remaining cards is your score. Whoever has the lowest score wins.

Alternatively, play multiple rounds until a player reaches 100 points, then once again whoever has the lowest score wins.
