Use the Train Mode (use T key) to train your skills before start cracking.

To open the safe, you must guess three numbers correctly. 

All safes have a range and a maximum number of attempts for each number.

 You will start entering any number you choose between  0  and  99. 

Three things can happen: 
- the number entered is correct
- the number is more less within the range
- the number you entered is out of range. 

Each case will produce a different click. 

It is your task to recognize them to know when you have guessed right and thus move on to the next number until you guess them all.
