One of my favorite mobile games (
Dead Trigger) recently launched a challenge. You can find a code in there game and the first 10 to decrypt it will receive a T-shirt. Before I share the solution with anyone, I'd like to give you a chance to crack the code as well:
02201010121021210121111011020201012110221021210202010121022210202111111102101012110101021001012021121020210121110221021201012101211100210201010121101010210010120220010121102011020211021012010101202112101211111101012021120101202021010120121201210012110121201211012120121201211
Good luck all.
P.S. Just got the confirmation I was lucky to be among the first 10 :-). I'll post a picture of the shirt as soon as it comes in.
