shuffleTiles関数

SHUFFLE: the tiles left, laid again in the slots they fill, so that play can go on. Drawn from the tiles themselves and how many shuffles came before (index), never from Math.random, so a solve replayed on the server — or a kept game opened again — shuffles to exactly the same tiles.

Laid in reverse, as a deal is, so what is left can be finished whenever the slots allow it. When they do not (two tiles stacked, nothing beside them), the tiles are laid with one matching pair on two free slots, so the next move exists; and where not even two slots are free, no shuffle can help and this answers null.
