Trace the word, follow the river.
Each level is a board of letters split into hidden streams. Read a clue, then drag through the letters of the answer, moving only across or down the board. Every letter is used by exactly one word, so the board always works out.
There is no penalty for a wrong guess: slide back over the last tile to undo it. Clear a pack of twelve levels to open a chest of coins, and travel the river through meadows, pine forests, canyons, snow, mangroves and the seaside.
