關於此遊戲

This is a card game that exercises memory ability:

1.At the beginning, all cards were randomly generated, and it can be confirmed that there are only 2 identical cards

2. Clicking on the card with the mouse will turn it to the front, and players need to remember the information of each card (including numbers, colors, and positions)

3.When clicking on the same card continuously, the card will not turn back, and the total number of card types and the number of cards found will be recorded in the middle of the screen

4.When all cards turn positive, the level is successfully passed!

The later the level, the more cards players need to remember. Try to flip all the cards in the shortest possible time. Come and challenge yourself!
