Unfifteen puzzle
A clever twist on the classic Fifteen Puzzle.
At first glance, Unfifteen looks simple — just arrange the tiles from 1 to 14 on a 4×4 grid. Two empty spaces should make it easier… right?
Not this time.
Each tile is hooked to the next one, with tiny connectors on the top and left sides. You can’t move a single tile on its own — only an entire row or column can slide together.
And that’s not all — the tiles can be easily removed and flipped.
On the reverse side, you’ll find black and yellow surfaces for even more creative challenges: arrange them in a chessboard pattern, form two large color blocks, or invent your own visual puzzle.
Unfifteen combines logic, dexterity, and creativity — a familiar concept reinvented into something entirely new.
