Play on top
Drop a tile right on top of a letter already on the board to turn one word into another. Put an O on the A in CAT and it becomes COT, and you score for every word you make.
A new dimension in word play.
The crossword game you know, with a twist: play your tiles on top of words already on the board. Stack letters up to three high, turn old words into new ones, and watch your score climb.
Every word on the board is a starting point. Three simple ideas make every turn a puzzle.

Each layer adds value. A tile stacked three high is worth far more than one sitting flat, so the best moves often go up instead of out.
Got two of the same letter in your rack? Combine them into one tile worth double the points, and pull a fresh tile from the bag to fill the gap.
