The team behind IQ Safe, a puzzle game that takes Sudoku elements and blends them with a safe-cracking premise, was excited to announce a quick sale for their title. Until August 23, you can pick up the mobile puzzle game for $2.99, rather than the regular price of $4.49.

The game was chosen alongside three other apps to be promoted at MWC in Barcelona. These four apps were chosen out of an amazing 3.750 applications.

The tutorial spans 19 levels, after which you’ll be able to dive headfirst into the campaign. In this mode you’ll travel to fifteen cities, each of which contains twelve missions for you to complete. In addition, there are 1,000 games which feature all of the same levels from the campaign, but with the puzzles reformatted in order to provide you with an additional challenge.
