In every turn, you have to input 3 numbers then the machine will tell you on how many of the numbers are correct and if its in the right combination but not in the proper position. You will be given five (5) attempts and once you exceeded the number of tries, the machine will reset itself and the code will change. Solving the puzzle will let you acquire the YELLOW KEY. With this, be patient.

H. Hurray! You have acquired all the 5 colored keys and you may now enter the through the portal to go to the next floor. (You could not enter the portal unless you have all five keys) BLACK KEY will transform into BLACK CHARM STONE and you have to discard it and repeat the step "G" before entering the seventh floor (7F) in every journey.
I.You will find a set of Shining Crystals (SC) on the eight floor (8F) (tha_t08,46 65) which is on your east from the point where you came from. Speak to the Shining Crystal and one of your keys will transform into a charm stone. Talk to the 2nd set of SC in (tha_t08 47, 147), 3rd set at (tha_t08 94, 150) and the last at (tha_t08 93, 59) and the key in your hand will transform into a corresponding charm stone.
J. Now, all the magical charm stones are in your possession and you may now open the pathway (tha_t08 112, 43) to the top of Thanatos Tower. Continue walking up to the floors until you reach the 12th Floor (12F)
K. Once you reached the 12th floor
