Step-by-step walkthrough

  1. Start the upper channels

    Fireboy walks left off his starting roof and drops into his matching lava pool. Walk right along the bank and pass the Purple lever to turn it on. Watergirl stays on the upper roof.

  2. Release the first two middle weights

    Watergirl walks right and pushes the first middle ball off its shelf. It rolls towards Orange. Jump right onto the next roof and push the next ball right towards Blue. Stop before the taller step. Leave the far-left ball in place.

  3. Close Purple again

    Once those two balls are travelling through their channels, Fireboy uses the nearby Purple lever again to turn it off. Wait for the Orange and Blue plates to stay down.

  4. Send the high weight to Yellow

    Watergirl jumps right onto the left edge of the highest small shelf. Approach its ball from the left and give it a short push right. Stop on the shelf as the ball falls away. Let it travel all the way to the Yellow plate at the bottom left.

  5. Wait before releasing the far-right weight

    Keep the last roof ball in place until the Yellow bridge has finished lowering. Releasing both weights together sends them into the same pocket and leaves Green empty.

  6. Send the far-right weight to Green

    Watergirl jumps right onto the last roof and pushes its ball right off the edge. Wait while it rolls back through the lower channels, crosses the lowered Yellow bridge and settles on Green at the far left.

  7. Return across the roof

    Watergirl jumps left from the right roof to the high shelf, then back over the middle roofs. Cross left to the remaining ball, approaching it from its left side.

  8. Open the diamond gate

    Push the remaining ball right and let it reach Pink in the right-hand pocket. All five plates should now stay down, and the pink gate on the upper left opens.

  9. Climb Fireboy up the left wall

    Fireboy walks left through his lava pool, then jumps onto the small sloping foothold against the far-left wall. Jump right onto the next ledge and right again through the open pink gate.

  10. Collect the required white diamond

    Walk Fireboy right inside the chamber to collect the white diamond. Return left, jump back through the gate and jump onto the higher foothold against the left wall.

  11. Return Fireboy to the roof

    Jump right from the upper wall foothold onto the starting roof. Both heroes can now cross the upper route to the right. The balls continue holding the five plates.

  12. Descend around the far-right edge

    For each hero, cross the middle roofs, jump onto the highest small shelf and then onto the far-right roof. Walk off its outer edge and follow the sloping bank down and left to the long lower shelf.

  13. Jump past the lowered Orange gate

    From the lower shelf, jump right over the lowered Orange gate. Drop around its outer side onto the bottom floor.

  14. Enter both matching exits

    Walk left along the bottom floor. Fireboy enters the red door and Watergirl enters the blue door. Either hero can enter first; the room finishes once both are safely inside.

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

  • Switch 1

    middle right

    Keep a hero or movable weight on this plate to keep its signal active. Stepping off releases it.

    Controls Moving platform 1.

If you get stuck

Check the unfinished objective

Count the ring-marked diamonds still visible. All 1 are required before both matching doors can finish this room; each hero collects their own color.

A gate or platform moved back

A pressure plate releases when its rider or weight leaves. Keep your partner on it until you are safely across. Levers stay set after you leave; check their ON or OFF state before crossing.

You missed a moving platform

Return to safe ground and use the connected switch to bring it back. Board before your partner releases the plate or changes the lever. Avoid jumping into its underside; line up with the open shaft first.

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.
