NEW 2h OLD WHEN SEEN

Words of Hanoi play screen: five test tubes of letter tiles with Moves and Par counters above and Undo and Reset buttons below.

TESIGN TAKE

Three lines of rules teach it, and the maker even explains why every board can be solved — that honesty is the charm.

AT A GLANCE

WHY IT MATTERS

Plenty of daily word games exist, but this one sorts letters instead of guessing them. Twelve letter tiles sit in five test tubes; you may move only the top tile onto a tube with room, and you win when every full tube spells a four-letter word. Boards are generated by walking 28 legal moves away from a solved position, so every board is provably solvable, every move can be undone, and any of the 902 listed words counts — not only the three the setter started from.

BUILD FROM THIS

A two- or three-minute daily habit next to your morning coffee
A friendly rivalry: copy the result strip and compare move counts on the same board
An experiment: rebuild a board from its seed with the unminified engine (/hanoi-engine.js) and hunt for a route shorter than par

WHO IT'S FOR

Word-game fan: wants one more puzzle in the daily routine
Family or coworkers: compare move counts on the same board
Aspiring puzzle maker: reads a real seeded generator and a solvability proof in plain code
