I've never heard of this before.
I found a flash version of the game and tried that out.
It's fun. I'm thinking of using something like this in my D&D game as a door puzzle now.

it's a pretty fun "straight math" game.  there are a number of versions of it.  i'd probably enjoy it on my iphone if i went hunting for the app.

as it applies to your diceless combat, you could scale the threat of the encounter to how long the puzzle chain was and how complicated the color wheel got.  Allowing bonuses to either effect that hard math or for reveals of the master code; proximity; clues etc...

anyway... good problems you've found for yourself.  i look forward in seeing what you do with it.
