There are three more challenges: the scrambled stones, the falling blocks, and the sand room. .
Scrambled Stones - When you reach the set of four blocks, push them off eith…er side to recreate the design on the wall below. This will open the wall. You can push them on top of each other to do this. (If you can't, pull the reset switch and try again.) Push one or more blocks across to jump from. .
Falling Blocks - When you climb down the rope and reach the chamber, the floor will collapse. There is a rope to get back up. You are back at the four hieroglyphics in the entryway. Remember the 4 symbols in ascending order (man, wavy sea, bird, eye) and jump on only those blocks, one block in each row. For example, only jump onto the big-head man in the first row, only the wavy sea block on the second. When you reach the top, jump quickly to the rope. .
Sand Room: For the last puzzle, there are 2 big statues and 4 little statues. Each little statue has dots on its belly (one dot, two dots, 3 , and 4). The switches each drop a little statue, but the room will begin to fill with sand. You must drop the statues in order (1 dot, 2 dots, 3, 4) before the sand covers the switches. The small mummy case opens to reveal the Blue Jewel . (you can reset the sand room in the hall at right) ( Full Answer )
