Packit In Flip

In this game, the player must find all pairs of matching cards.

The player starts off by selecting a grid size - they can choose between 20, 30, or 40 cards. The cards are shuffled and initialized to be displayed face down. The player needs to tap cards to flip them over and match them with their corresponding pair.

The player's score is calculated as the difference between the number of total attempts and the number of successful matches.
Similar to golf, the lower the score, the better. Theoretically, the best score the player can obtain would be -10 with a grid size of 20.
