Sliding tiles through a vacancy
Adjacent tiles slide into a vacancy. Position the empty space before moving the desired tile.
The player's decision
Displace a correct tile temporarily to make room for the target's turn?
Original scenario
Original setup: keeping a correct corner fixed prevents two lower tiles from being reordered; route the vacancy around it.
Start with this prototype
Build a 3×3 board with one vacancy, scrambled through legal moves. Include undo, move count and target preview. Win by restoring order; never generate by arbitrary permutation.
Change one variable
Increase scramble length but measure shortest solutions; shuffle count is not guaranteed difficulty.
What to observe in a playtest
Are generated boards solvable? Does undo restore vacancy and count without overlapping rapid moves?

Original analysis · version 1
Common pitfall
Inconsistent tile-versus-vacancy arrow semantics make controls confusing.
