Step-by-step walkthrough
Open the orange passage
Fireboy stands on the bottom orange plate. Watergirl approaches the left wall and jumps into the orange crystal. After arriving above, move right onto the lower shelf, return to its raised left end, then jump onto the higher orange plate. Keep that plate pressed while Fireboy follows.
Collect the lower left diamonds
Fireboy explores the lower left shelf for his red diamond. Watergirl collects the blue diamonds on the lower shelves and the diagonal middle ledge. Use the raised left end of the lower shelf to jump back onto the orange plate, then cross right and climb the narrow shelves above it.
Ride the timed fan
Climb left onto the purple pressure plate. Jump left into the fan, rise along the wall, and steer right onto the upper shelf. Fireboy collects the red diamond beside the fan; Watergirl collects the high blue diamond in the wind. Both heroes can follow this route, activating the plate before each ride.
Balance the seesaw together
Cross the top shelves to the seesaw. Fireboy stands near its right end while Watergirl jumps near its left end. Let the beam settle, then Watergirl jumps again to collect the highest blue diamond.
Open the right-hand gate
Watergirl stays near the left end to raise Fireboy’s end of the seesaw. Fireboy walks to its right tip and jumps to the high ledge, collecting the red diamond on the way. Walk across the green lever to open the gate below.
Return for the middle red diamond
Fireboy returns left over the seesaw and upper shelves. Drop from the left side of the top shelf, cross the purple plate and jump onto the diagonal middle shelf. Follow it right through the red diamond. Return left through the stepped shelves and ride the fan again.
Descend through the lava
Cross the seesaw again and walk off its right end, keeping the green lever switched on. Pass through the open gate to the middle gallery and collect its red diamond. Fireboy descends through the lava terraces, collecting every red diamond, then stands on the bottom yellow plate.
Bring Watergirl down safely
Watergirl crosses the seesaw and open gate, collecting the right-hand blue diamond. Walk left along the gallery into the powered yellow crystal. After emerging below, move left onto the yellow pressure plate so Fireboy can leave it.
Reach Fireboy’s exit
Fireboy jumps right over the small bottom mound towards the white floor crystal. He emerges below the ceiling in the exit tower. Land on the upper shelf, walk off its left edge, then steer right immediately towards the lower red door.
Collect the three blue tower diamonds
Watergirl follows through the bottom white crystal, collecting the lowest blue diamond during the approach. From the upper exit shelf, jump left for the high blue diamond, then continue down the shaft through the middle blue diamond. The bottom white crystal returns her to the blue exit shelf.
Finish together
Check that all eighteen diamonds are collected. Fireboy stands in the lower red door and Watergirl in the upper blue door. Either hero can arrive first; the room completes when both reach their matching exits.
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.

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.
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.
