Vs. Pair-a-Gone

Vs. Pair-a-Gone is a minigame exclusive to the Vs. Battle mode in New Super Mario Bros.. It is one of the 1 on 1 minigames featured.

The minigame plays exactly like it's single-player counterpart, Pair-a-Gone. Both players must clear the cards off their table by tapping two identical cards adjacent to each other, be it horizontally, vertically, or diagonally. Both players start with thirty cards, and any pairs that are cleared are placed in the opponent's deck. The player with the least amount of cards overall when the time is up is the winner.

In-game instructions
"Match up cards horizontally, vertically, or diagonally to remove them from the table. Cleared cards move to your opponent's table. The player with the fewest cards when time runs out wins."
