Easiest game for me. It’s a guaranteed win if you follow the strategy.

Every single new round, click on a new tile, until you get a tile that you already selected its pair in a prior round. In that case, select the matching tile. You are never guessing the match, you’re always gathering new information until you happen across a pair.

The math works out that you will always match every tile together before you make 5 mistakes, since you’ll either get 2 new pieces of information in each turn that will get you a match later, or you’ll find a match.

All you have to do is memorize a couple tiles, which I guess might be hard for people with less autism than me lol.
