How to play
Match the target pattern before the 2:00 timer reaches zero. The target remains visible throughout the round.
Only the top disc on a tower can move. Select its tower, then select a different destination tower with a free slot.
Every successful forward move adds one Step. Undo reverses the most recent move; Reset restores the full starting board.
Disc letters repeat their color identity, so the pattern is readable without relying on hue alone.
In the real assessment
Five discs and three towers are patent-supported, while the exact time limit and presence of both Undo and Reset still need production footage. This reconstruction uses the recommended 120-second, click-to-select defaults.
