What’s the logic game? I’d also love to find more games like these for my kids (they love playing with Euclidea, but it’s too abstract for them to grasp).

Another one they do manage to understand (and love) is Lightbot http://lightbot.com

Circuit Scramble

It's so good I managed to do all 135 puzzles in two days and another few hundred generated ones.

The generator might need some work. A lot of the ones it makes are too simple, solvable in 1 or two moves.

I know of two other mathy game apps: Torus games (games like tic tac toe on a torus, Klein bottle etc.) and Pythagorea (which is about geometry)

DragonBox Algebra is tons of fun.
