Try a new twist on crossword puzzles, in which clues and words are replaced by random lists of letters. Deprived of clues of where words appear in the puzzle, you are forced to use pure logic to determine how the random letter strings fit into the puzzle. The default puzzle size is 9x9 and the app includes 7 other puzzle sizes as well.

To play, tap an input (on the right side of the window) then tap the cell where the input should begin within the crossword grid. If you make a mistake, fret not - a small time penalty will be charged, and a cell will be filled in. Completed strings will be crossed off the list automatically. Complete the puzzle in the fastest time possible, then challenge friends to beat your best.
