Every letter on the board belongs to exactly one word. Find them all.
Tap · tap touching letters one at a time, in any direction including diagonal, then tap the last letter a second time to finish the word.
Four letters or more.
Each word sits in one place · a theme word can be spelled exactly one way on the board, so the letters you tap are the ones that count. Nothing gets moved for you.
A wrong word is never wasted · find three real words that are not among the board’s answers, and you earn a hint.
A hint · lights up one theme word, first letter to last, and numbers them so you can still read the order afterwards.
No clock, no score. The board is either covered or it isn’t.
