Concentration is a memory game in which you match unique pairs in a group of cards face down. You select two cards to flip over. If the cards are of the same type, you get points but if they don't, the cards flip face down again. The goal of the game is to match all the cards to their same type for each round. 5 extra bonus points are awarded for completing each round before the timer runs out. TL;DR: that memory game that you probably have played before. Controls: Click on the cards to flip them over.
This was the challenge for the ms coding competition at nationals TSA. This is a good example to prepare for the Coding event if you are interested. Thanks to my teammate for working together.
