This app is a new kind of the classic Sudoku game. With this app, users can choose three different types of Sudoku games to play: 1. The classic Sudoku games that use numbers 1 to 9. 2. New Sudoku games that use interesting figures instead of numbers. A different set of figures are used in each game to keep the games challenging. 3. New Sudoku games that use letters (A to I) instead of numbers. Added to the above, users may choose six different game levels to challenge their logic and analytic skills. Moreover, in each game, the app will notify users if they select an item (number, letter or figure) for location is in conflict with the same item that is already set in the same row, column or quadrant with respect to that location. This ensures users will always be able to complete every game they play. Furthermore, to make games even more interesting, users may choose if there is a time limit or no time limit set for each game. Also, you may turn-on/off sound  effects that are used to alert users when they have completed one row, one column, one quadrant, the entire game or the game time has expired. Finally, after a game is completed, the app will display game statistics  and compare that to any of your past best game results for the same game level. This aids you to gauge your progress in improving your game solving skills.

Brain Code is a command-line-inspired puzzle game. Read a level, type a command, and use the response to work out what to try next. It’s a game about clues and logic, not a coding lesson. Explore 50 handcrafted levels. Some clues ask you to think beyond the obvious answer. No programming experience is needed: curiosity and careful observation are enough to begin. If you get stuck, optional in-game hints can give you a nudge. You can also leave a puzzle and return to it later. The levels can be played offline. Ready to try a different way of thinking? Start with the first level and see where your next command takes you. Questions or a bug to report? contact.kkapps@gmail.com Reading the description again? The last two lines may help.
