Hack Types
| Type | Image | Description |
|---|---|---|
| Sphere Trace |  |
The player must connect two blue points together by moving one or both, while avoiding red dots. Difficulty determines how many times it must be done, the speed of the red dots and the length of the trails they leave behind. |
| Point Search |  |
The player must move a central core such that the lasers leading to the core also pass through several points arranged around an area. Difficulty determines the number of connection points and cores needed to align. |
| Point Match |  |
The player must connect colored pairs of nodes by memory, while also contending with a dividing barrier. Difficulty determines the number of pairs and allowed failures. |
| Rod Pull |  |
The player must rotate a wedge such that it passes through a small opening in three partial circles. Difficulty has not been implemented on this puzzle. The basic puzzle allows for collisions by adding additional circles to the end of the rod. |
| Point Drag |  |
The Player must drag a point through several circles while a "fuse" burns down along the same path. Difficulty will reduce the visibility of future circles and increase the fuse speed. |
| Simple Activate / Toner interact |  |
No puzzle interaction. Basically a variation of a button for electronics. |
