Apologies for the shameless self-promotion ahead.

I’ve recently published a free 2D logic puzzle app, which I'm hoping will appeal to speed solvers. The app comes with 272 logic puzzles, in five difficulty levels, pre-loaded. I've watched an eleven year old solve a level one puzzle in 10 seconds, but 3/4 of the level five puzzles have never been solved - not even by me.

The rules that govern how the cogs behave are :

Rule 1 – Each Cogismo puzzle is made up of nine cogs. At the start of the puzzle each cog is displaying a number between zero and nine.

Rule 2 – When you tap on a cog, that cog will rotate 90 degrees clockwise and the number being displayed on the cog will be incremented by one. A one will become a two, a two will become a three, etc. When a nine is tapped, it will become a zero.

Rule 3 – The puzzle is solved when you get all nine cogs to display the number zero.

It’s that simple, except for one little thing…

Rule 4 – The cogs have one or more teeth protruding from the side. Two teeth can never occupy the same location. When a tooth on a rotating cog strikes a tooth on a stationary cog, then the stationary cog will rotate (just as if you had tapped on it).​

On the hardest levels, to solve a Cogismo puzzle you need to be thinking 20+ moves ahead.

The app is small (24Mb), free, and it has minimal in-app advertising. If you are interested in checking it out, then the links are below -
