I just downloaded and played a timed game. Your goal is to match all 10 pair of shapes on the left and right by selecting one letter from each column to make a word. Letters can weave up and down as you move across. When you match all the shapes you unlock the next level. Then you concentrate on finding the remaining words before your time runs out.
Each letter is worth 20 point so a 4 letter word on first level is worth 80 points. The length of the words increases on higher levels. A bonus of 800 points given if you find all the words on the board.
The words on the board are in alphabetical order which help find words like Every Word.
There is a tutorial mode if you are new to the game. You can also use the keyboard instead of 5-way controller. I found typing worked faster for me.
Checking the words you miss afterwards is always good for vocabulary building.
Amazon came up with another fun word game. Give it a try.
