In my words 2C edges and 3C corners are "elements" not pieces. Pieces are stickers.

I will play with "dode F 2:0:1" instead of "cube E 1:0:1". The 2C edges stay together and the 1C faces and corners can’t be dissected.

Why do you think that Nan has not solved the small "cube E 1:0:1" ?

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.

Hi Roice,<br>
In MagicTile some puzzles become completely unplayable, if  the depth is chosen so that individualised multicolor elements can be separated in pieces. In this case it would be necessary to label all these pieces which cannot be done in your program easily. When the the puzzle is solved in MT&#58; when colors are okay or when all pieces are at home?<br>
I tried MT ell/sphere/cube/E 1&#58;0&#58;1. Edges can be dissected!<br>
