Emoji Matching Game
This game is a simple Emoji Matching Game where the objective is to find pairs of matching emoji pictograms. The game board consists of randomly shuffled emojis, and you can click on each card to reveal its corresponding emoji. If two revealed cards match, they will turn green and disappear. If they don't match, they will be hidden again after a short delay. The game continues until all pairs have been found.
