Letter Box

Check it out in iTunes!

Our latest word app is more a game than a literacy tool.  The idea is simple – players are given a grid of letter tiles.  The tiles need to be re-arranged so that the entire grid spells words in every row and column.  The game has three grid sizes: 3×3, 4×4 and 5×5.

Once we had our puzzle database, it’s a simple matter of curating new and unique packs of 25 puzzles at a time for each update we put out.  The app is free, with a pack of 25 puzzles available from the start.  After that, you can unlock all packs of a certain grid size for 99 cents, or you can unlock the entire app for $1.99.
