Description
The player must solve math and spelling problems to open the locks on the bone vault. First the player must click on the red dial on the rotary combination lock to begin. Then the player must press the dial to stop on the correct number or letter that completes the problem.

In math mode, the player must find the number to solve the equation. In spelling mode, the player must find the vowel that correctly fills the blank in a word.

When the vault has been opened, the player can access the Measuring and Weighing Room. In this room, the player can use a ruler to find the length, width or height of objects, and a scale to find the weight of objects.

There are eight items that can be measured:
