神経衰弱 is a classic card game where players have to find matching pairs of cards with the same number. The game offers various modes, including a single-player mode where players can compete against the computer and a two-player mode where players can play together on the same device.

In the two-player mode, players can choose to play side by side or face to face, making it easy to enjoy the game in a way that suits them best.

The single-player mode is a challenge mode where players have to complete all 30 stages within a time limit and a limited number of mistakes. As the game progresses, the number of cards increases and the time limit becomes shorter, making it a great memory training exercise.

In addition to the regular deck of cards, the game also offers a simplified design for easy visibility. Best of all, the game is completely free to play, so give it a try and test your memory skills!
