Hi Ed,

Puzzles are solved in MT when all sticker colors are the same on every
puzzle face. So on the puzzle you mention, a sticker may not necessarily
end up exactly where it began. The stickers of dissected edge pieces may
end up reconnected with different stickers in the end. (However, there may
be parity-like constraints that limit how stickers can go back together - I
haven’t analyzed this particular puzzle with respect to that.)

In fact, MT has no internal concept of "pieces", e.g. 2C edges or 3C
corners. It only knows about stickers, and if some stickers always remain
connected to others due to the slicing particulars, MT is blissfully
unaware of this :)

In any case, the puzzles should still be playable without labeling pieces.
A nice extension in the future would be picture puzzles, which would
effectively label the pieces and require dissected edges to go back exactly
as they started.

seeya,
Roice
