Clear the Square ($1.99) by Digital Earthenware is a puzzle game where you are given a grid of letters to use to create as many words as possible.
To create a word, just tap the relevant letters in the correct order and tap the enter button. This will cause those letters to disappear from the board.
The longer the words, the higher your score, which can then appear on the top 10 list of the high score board. The tricky part is that your score does not count and cannot appear in the top 10 if you don’t entirely clear the board. Doing so might be a matter of skill with words, but it also seems to be a matter of luck.
You have the option of selecting a four by four, five by five or six by six grid and there are over 160,000 words.
Clear The Square is a rather simple game to play, but for those who love word puzzles it’s sure to be a treat. There is a free version too.
