How do I solve the yellow, green and blue Artifact puzzle?
Guide each water drop over yellow build cells to the three green collectors; blue cells remove the water.
Quick answer
Build guides only on the yellow squares, then route falling water into all three green collector boxes. Avoid the blue squares because they remove or reset the water. The collectors can be completed over multiple drops; the door opens when all three are green.
Steps
- Use the yellow squares as the cells where you can build a route for falling water.
- Guide the first drop to a green collector without touching a blue square.
- Press the room button again and redirect later drops to the remaining collectors.
- Finish when all three collectors or cables show green and the door opens.
Requirements / limits
- This answer covers the color logic, not a copied tile layout.
- Update #1 fixed missing and deletable reset buttons; Update #2 did not change the logic.
- If the room will not reset in 0.5.5, reload before treating it as unsolvable.
Common mistakes
- Sending water across blue cells.
- Trying to activate all three collectors with one drop.
- Rebuilding indefinitely when the reset button is stuck.
