Pure mathematics is the world's best game. It is more absorbing than chess, more of a gamble than poker, and lasts longer than Monopoly. It's free. It can be played anywhere - Archimedes did it in a bathtub
I just bought this and I find that the pawns can't pass in a corridor without running up against the walls or repelling the passed pawn across the wall! It's a really cute concept, but that's a major flaw! The injunction to slide quickly might help, but not by much. The board is just too small for magnets of that strength. Maybe I'll try smaller ball bearings... that might fix the problem.
I have never had problem with that. You simply move the inactive pawn a bit to a corner and there are enough space for the other pawn to cross.
