Sphere Generator solution
The Sphere Generator in Ultima VII involves navigating a maze of eight platforms where the Avatar must walk through either a series of moongates. The Generator is a key plan the the Guardian's conquest of Britannia and removing its prism, located within the maze, is necessary for its destruction. This task is further complicated by the fact that some gates set the Avatar back, while others dump the hero into malevolent fields located in Dungeon Shame. Even though small glowing spheres blink in a sequence that already spoils the solution of which order to walk through the gates, a more detailed look at the puzzle is shown below.
Detailed Solution[edit]
In the following solution, the Avatar starts on platform 4 and must reach platform 8, where the prism is located. The spheres blink in the pattern red - blue - blue - red, which is the fastest solution to the problem. This means the platforms 4 - 1 - 6 - 3 - 8 are to be visited in this order.
| Platform | Red Gate to | Blue Gate to |
|---|---|---|
| 1 (NE) | 5 | 6 |
| 2 (E) | 1 | sleep fields |
| 3 (SE) | 8 | 2 |
| 4 (S) | 1 | 7 |
| 5 (SW) | fire fields | 6 |
| 6 (W) | 5 | 3 |
| 7 (NW) | 1 | poison fields |
| 8 (N) |
