Touch the Prime Numbers

Created by a Prime Numbers fan—can you relate? I have had this game app for several years and play with it only infrequently. But I would never delete it. Mr. Rucky is a quirky, lovely man—at least he was back when I knew him. Not as far back as Ohio Boys’ State, of course. But back in the “Facio liberos” era.

good app if you're trying to memorize the prime numbers between 1-100...

Tap the prime numbers. Sounds simple, right? Well, sort of. It took some trial, error and frustration to figure out that the game wants you to tap the numbers in order. If you spot 5 and tap it before you spot and tap 2, nothing happens. The game is so "simple" that the programmer didn't bother including a brief tutorial to explain this, so you just have to figure it out on your own, i.e., by accident. You could tap every single prime number presented, but if you don't know to tap 2 first and 3 next, the game appears unresponsive. "Helpfully," there's a number displayed in the upper right of the screen: the number you're looking for next. Also only obvious once you figure out that you should be tapping the numbers in order— otherwise, as that number doesn't change until you're on to the next number, it doesn't seem to signify anything. But once you do know that the number is your guide to what to tap next, it provides two services in one: 1) It's distracting, and 2) it robs the "simple" game of any possible challenge. What a terrible game.
