The symbols on the doors have corresponding numbers starting from 0 to 9, from the bottom left going to the bottom right of the door.

Each of them has a missing number that you have to obtain by rolling the two question marks that can be found on the walls in the same area of the door.

To solve the puzzle with the number 21, you have to roll the question mark to the symbol that corresponds to the number 8 in order to get a total of 21 when combined with all three numbers from the puzzle.

The second quest mark can be found on the upper platform going through the stairs, and it will be on the front wall. To make it right, roll it to the hydra symbol.

This will combine the three numbers, and get the number 17 in total which will solve the puzzle on the door.

Now, you can open the door and continue forward with the exploration.
