Step-by-step walkthrough

  1. Take turns through the dark chamber

    The light around each hero reveals nearby terrain. Leave one hero safely at the upper-right start while the other completes the route, then follow with the second hero. This room has no diamonds or switches.

  2. Cross the upper walkway to the left

    Descend LEFT from the starting ledge. Fireboy can walk through the red pools but must jump over the middle blue pool. Watergirl must jump over both red pools and can cross the blue one. Continue to the pointed far-left end and drop onto the next walkway.

  3. Return right across the second row

    Head RIGHT along the middle walkway. Fireboy jumps over the first and last blue pools; Watergirl jumps over the middle red pool. Continue past the pointed right end and drop onto the right-hand ledge below.

  4. Jump the short purple pool

    Turn LEFT on the lower-right ledge. Jump across the short purple pool and land on its left side. Both heroes must avoid this pool. Stop near the ledge’s left edge before the much longer purple pool below.

  5. Use the hanging plank

    Jump LEFT onto the right end of the hanging plank. Move toward its left end while it tilts under your weight, then jump LEFT onto the stone slope beyond the long purple pool. Cross with one hero at a time so the other hero does not change its balance.

  6. Leave by the lower-left passage

    Follow the stone slope LEFT over its high point, then descend to its pointed left end. Step off to the LEFT and drop onto the basement floor.

  7. Climb the basement mound

    Turn RIGHT and jump up the large stone mound on the basement floor. Cross its summit and descend its right slope. The rest of the bottom passage has no pools.

  8. Wait at the matching exit

    Fireboy stops at the first, orange door; Watergirl continues to the blue door farther right. Repeat the route with the waiting hero. Both heroes at their matching doors finish the room.

This route was verified in the game simulation using player controls, required diamonds, and both matching exits. It describes this version’s independently reconstructed room, not an official walkthrough.

How this room’s mechanisms work

  • Hanging plank 1

    lower center

    Its position responds to the weight and position of riders.

    Balance on the hanging plank, then jump to the next dry ledge.

If you get stuck

Check the unfinished objective

The diamonds in this room are optional. If you only want to finish, bring both heroes fully inside their own matching doors.

You cannot recover safely

Pause and choose Restart level to reset both heroes, diamonds, weights, and switches. Previously completed levels stay saved. Follow the step order before moving a box or releasing a weight.
