Memory Pets

In the Memory Pets game, there is a grid board containing small cards and a timer. When the game starts, the board starts to show all images on cards in mixed sequence for a short time and hide them immediately. Then, the timer starts, and the player needs to memorize and match the same cards before the time is over. When players tap on a card, it will show the image and if it matches with the next card that the player tapped, they will not turn back. If a player can match all cards in a given time, will be rewarded with Pethereum Crystals and proceed to the next level.
If a player fails to match cards in a given time, the game is over.
