Click the green play button to begin a new game, then find the words hiding among the letters. Enjoy!
Tip: the hidden words hide by spelling themselves horizontally, vertically, forwards and backwards, and will often twist & turn around other letters too, so look (and think) in all directions simultaneously. Click the brain if you need help, click the audio settings cog to mute the music & sound effects, and click the reload button to restart the game.
