As a senior, I’m very attracted to games like this. But these are very poorly developed.The first game I played asked me to tap on matching cards. Several cards are displayed, they quickly turn face down, and I then tap on the pairs. It seemed fun at first, but the number of cards displayed grew way too fast. And there wasn’t even time to look at them all before they immediately turned over!Tip: Let *us* tap a button to flip the cards face down when we’re ready.So I decided to try different game. The second one had different colored shapes floating around on the screen. My job was to tap on the on that was fixed at the top.This may sound unbelievable, but more than once the fixed shape at the top *didn’t even exist among the ones floating below*! Yes, there was no match. I played more than once, and it happened in each game.I didn’t try any others. Very few of the games are free, as a subscription is required to unlock many of the others. So I simply uninstalled.
