Pretty good version of this classic game, although the "flashes" throw you off as they're not all the same. The maroonish color flashes a violet-ish color so you see that flash and you know it's the purple one. But some colors flash white-ish instead of versions of the color so your mind thinks "white" until then flash is done...then you go, that's not white, it's orange or grey or dark grey or whatever. Anyways, small gripe...but it throws off your rhythm after you get above 25 or so.

The color flashes has now been improved with clear colors, more like the original lamps. Please update to latest version. Thank you for your review.

So many options! I love it, I've always used simon to improve my memory but I hated how you could never choose a level to start at. This game lets you do that and so much more. My goal is to be able to start at the Chuck Norris level (20 note) pattern with no problems.

Excellent version of the 1970s game. Great options to vary the game, if you wish. A small download size. Simple menus. No ads... ...thank you, developers...nothing kills a game quicker, I reckon.
