Nice puzzle. The magnet puzzle combines well with the +/-1 rule. I rediscovered this puzzle after I solved half of it some time ago but then never got around to finishing it. And because it did not have enough solvers to have a rating it kind of disappeared from my radar. That is solved now too.
The part about the S's in the solution code is missing from the English description, by the way.
