Two mirrors, three exits (Mirror Isles 10)

Two mirrors can give you two traders, but the goal asks for three. A trader outside the mirror lines can remain while another reflects.

Keep one trader above the mirrors’ row and duplicate the other. On the lower island, use the raised northern ledge to spread the three traders into alternating columns.

The route was checked against native-demo footage and manually reproduced in Joric’s separate community PuzzleScript player on September 13, 2026. Every exit was occupied in that recreation. Kingy has not replayed it in the native demo or verified the current native build.

The real traders move together; an edge can hold one while another continues. The counted movement table starts from the untouched room. “Reflect” means the configured reflection action, not an assumed physical key. Counts include moves stopped by an edge; follow each input in order.

1. Push the left mirror down twice so both mirrors share a row. Stand two tiles west of the right mirror. The two projections should land on the lower island’s far-left edge and on the upper island’s short southern extension.
2. Activate reflection to make two real traders. Move up once, then left, up and left. Water holds the lower trader while the upper one walks around the right mirror and returns to the duplication position.
3. Reflect again. The lower trader comes back to the upper mirror row; the other returns to the southern extension. There are still two real traders. Move up, left, up and left: one now stands above the mirror row and the other at the duplication position.
4. Reflect a third time. The northern trader stays in place while the aligned trader becomes two. All three are visible at 3:57. From here they continue to share movement.
5. Move up twice. The lower trader moves once before water holds it; the northern trader stays at the upper edge; the trader beneath the right mirror pushes it up once. Moving this mirror out of the other mirror’s row prevents the same duplication setup from repeating.
6. Move right twice, down twice and left twice. The upper traders should be on the causeway and southern part of the right lobe, with the lower trader at its southwestern boundary. Move right twice again. At 4:05 the causeway trader projects onto the lower island’s far-left upper tile. Reflect to transfer it.
7. Move left three times, up once and left twice. This brings the last upper trader onto the causeway’s reflection position while the two lower traders gather at their western edge. At 4:09 the projected landing is occupied and red.
8. Move right once to clear that landing and change the projected destination. Reflect again. All three traders are now below: two beside each other near the far-left edge and one directly above the right-hand trader. Compare 4:11 before continuing.
9. Shift the group one tile right and then up. The front trader enters the raised northern ledge. Move left once: its ledge edge holds it while the two lower traders move left. Move right twice, up once and down once. All three should now form an adjacent row below the ledge, as at 4:18.
10. Move the row right twice, then up. Only the left two traders can enter the raised ledge; the right trader stays one row below. Move right once, down once, right once and up once. One trader is now on the ledge, with the other two below and to its right.
11. Move right once. The ledge holds its trader while the others move farther right, leaving one empty column between each trader. Move down once and left once, then down until all three reach the island’s southern edge. This removes their vertical offset.
12. Move left twice along the bottom row to stand directly below the three exits. Move up once. All three exits are occupied at 4:26, just as YouTube’s next chapter label begins.
