"Of All the Luck"
Pursued by Hacker, Digit lands on cybersite Eureeka, where his mission is to find Professor Archimedes — the maker of the encryptor chip, a unique computer chip that can fix Motherboard. But Archimedes is nowhere to be found — only a pile of 2-dimensional rods where his chip factory should be. The kids arrive to help, and discover that by linking the 2-dimensional rods together into certain geometrical patterns they create a surprising 3-dimensional shape that leads directly to unraveling the mystery of Archimedes' strange disappearance.

- For Real Segment: "All Dolled Up" - Harry orders a dollhouse for his sister, but it comes in the form of flat cardboard pieces. He must join the two-dimentional pieces together to create the 3-D dollhouse.
