Do you need to waste a couple of minutes? Then you can do so and work your brain at the same time.
SafeCracker is a code breaking game in which you must guess the combination to the safe to get whatever is hidden inside. Simply use the number wheels to put in your guess then try the handle. If your guess is correct the lights will turn green. Next the handle will turn. Then your prize will be revealed. However if you are not correct lights will show up to help you with your next guess.
Red - The number is not in the code.
Yellow - The number is in the code but in a different spot.
Green - The number is correct.
There are 10 unique safe designs and the safes can contain from 2 to 5 dials. This gives you a combination of 40 different safes to open. Also there are 21 items to find in the safes and the game will keep track of your collection.
Think 5 dial safes are too hard or 2 dial safes are too easy. No problem just go into the settings and turn them off. You can have as much or as little challenge as you want.
The app is currently available in the app store for $.99. A new update is in work currently but I do not know when I will be finished.
