Observations on tilt-mazes...
Tilt is actually one manifestation of the simplest of multi-state maze-rules. The must-go-straight rule or, more simply, the bridge. Most people probably would not consider a maze with bridges truly multi-state (I didn't for a long time, note how I separate under-and-over mazes from direction-control mazes in my maze-gallery). However, from a two-dimensional viewpoint, when you stand on a bridge you are clearly in one of two states, either on the upper-path or the lower-path, and clearly climbing from one state to another is not permitted.

In the tilt-maze, as in many multi-state mazes, the bridge is implicit. Any (square) cell that is lacking all four wall creates a bridge (a hexagonal cell creates potential for a triple-bridge). Far more subtle in a tilt-maze however are the half-bridges, created by a cell with a wall on only one side. The effect of the half-bridge is rather like a half-built fly-over where, unless you simply reverse, you end up dropping from the upper-road to the lower-road and (most importantly) you are not permitted to reverse this decision. Every junction in a tilt maze is effectively one of these half-built fly-overs, which means every significant decision you make is non-reversible. You can easily end up right back at the beginning or, worse still, completely stuck.

Thus the tilt-maze combines two of the simplest yet most powerful maze-constructs, the bridge and the one-way-arrow, but does so with almost complete transparency, making the trickery very hard to spot.
