Sherlock Holmes versus Arsene Lupin Hints

How do I load the cannon?

  • 1 of 10: You can find a document detailing the charges needed for cannons.
  • 2 of 10: It is on the desk in the dormitory.
  • 3 of 10: It will tell you the measurements you require.
  • 4 of 10: The cannon is a 2.5 incher, so it needs 478 cubed centimeters of charge to work.
  • 5 of 10: Click on the cannon to begin the puzzle.
  • 6 of 10: You should have collected the two containers from the arsenal by this point, if not, go back and get them.
  • 7 of 10: You need to make a total of 478 using the values 250, 80, and 12.
  • 8 of 10: 19 multiplied by 12 is 228.
  • 9 of 10: So, put 19 of the 12cc containers into the bag, followed by one 250cc, to bring the total up to 478cc.
  • 10 of 10: If you did it correctly, Holmes will tell you so.
