Shifty Letters is a puzzle game where you use falling blocks to form words. Words are scored based on the value of the letter tiles.
Featuring over 100,000 words to form horizontally, vertically, or diagonally. Use random double-word and letter-scoring tiles to increase your score. Every 500 points, select a modifier to help you stay alive. The game is over once your blocks reach the top.
Play against two to three other players locally or go head-to-head with someone online. Words with five letters or more will create frozen blocks on your opponent's side. Unfreeze them by making a word that touches those blocks.
For those looking for more, test your skill in the daily challenge where you must spell 20 random words to win.
