Every letter on the board belongs to exactly one word. Find them all.
Trace or tap · drag across touching letters, any direction including diagonal, or tap them one at a time and tap the last letter twice.
Four letters or more.
Each word sits in one place · a theme word can be traced exactly one way on the board, so what you trace is what counts. Nothing gets moved for you.
A wrong word is never wasted · find three real words that aren’t part of the theme 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.
Take a word back · tap it.
No clock, no score. The board is either covered or it isn’t.
