Quest 1:
Find the right number. Each time after selecting a number, the log will display how many digits in the number are in their places. How many are out of place. For example, if the correct combination is 1234, and you chose 1293, the answer will be “2 - in place" (1 and 2) and “1 - not in place" (3). Use logic to determine the correct combination. The number of responses is limited.
Quest 2:
Find the correct password. Every time the correct password partially matches the selected one, its parts will be opened. The number of attempts is limited.
You can adjust the length of the "password", choose a hexadecimal or decimal system and other parameters to change the complexity. Documentation included.
