Step-by-step walkthrough
Cross the first pools
Fireboy jumps across the two upper blue pools, taking the red diamond over the first crossing. Watergirl follows through her pools, jumping over their banks, and takes the far-right blue diamond. Both descend onto the sloping shelf below.
Open the route to the hanging bridge
Watergirl walks left through the long blue basin, takes its diamond, jumps over the left bank and drops to the green handle. Fireboy approaches the bridge from the right slope and jumps left onto the hanging plank. Jump left again through the opened passage to collect the red diamond and land beside Watergirl.
Collect the middle pair
Fireboy jumps across the next blue basin for the red diamond hanging above it. Watergirl crosses that basin, climbs the right slope and jumps off its right ledge for the next blue diamond. She lands in the lower blue pool beside the block.
Make a safe landing with the block
Watergirl jumps left over the block, then pushes it right until it sits beneath the right end of the ledge above. She jumps back to the dry left bank. Fireboy steps off that upper ledge, drops onto the moved block and jumps left onto the dry shelf for the next red diamond.
Explore the next chamber
Watergirl follows the left end of this shelf down to the outer blue diamond and the blue sliding platform. Fireboy also drops left, crosses the middle shelf, jumps the gap to the right and collects the red diamond above the right-hand ledge. He returns across the gap, drops through its inner opening and lands on the lower sloping floor.
Lower and raise the yellow lift
Watergirl crosses the middle shelf for its blue diamond, jumps to the right ledge and holds the yellow plate. Wait for the inner yellow lift to reach its lowest position. Fireboy jumps left onto it, taking the red diamond. Watergirl steps away from yellow so the lift rises, then Fireboy jumps right onto the cyan plate.
Open the final passage
Keep Fireboy on cyan. Watergirl drops through the middle opening and walks right through the raised cyan barrier. Jump for the right-hand blue diamond, then touch the purple handle. Return left through cyan and take the blue diamond above the lower sloping floor. Fireboy steps left onto the inner yellow lift and waits there.
Return Watergirl to yellow
Watergirl descends to the bottom, touches the blue handle and crosses the blue pool at the far left. Climb the alternating outer ledges. At each ledge, stand clear of the one above, jump upward first and then steer across. Use the shifted blue platform to regain the upper shelf, cross the middle gap and hold yellow again.
Release Fireboy and gather the last diamond
Wait for Fireboy’s lift to lower. He can now step right beneath the cyan-plate shelf, drop to the bottom and collect the last red diamond. Watergirl leaves yellow, returns through the middle opening and follows the lower floor to the opened purple passage.
Finish at both doors
Fireboy’s door is on the bottom-right floor. Watergirl stands to the right of her raised exit shelf, jumps straight upward before steering left, and lands at the blue door. Either hero may enter first; all fourteen diamonds are collected before the finish.
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 center
Walk past the handle, or use it nearby: Enter for Fireboy, E for Watergirl, or the touch Use button. Each use toggles it; it stays set after you leave.
Controls Moving platform 1.
Switch 2
lower center
Walk past the handle, or use it nearby: Enter for Fireboy, E for Watergirl, or the touch Use button. Each use toggles it; it stays set after you leave.
Controls Moving platform 2.
Switch 3
middle right
Keep a hero or movable weight on this plate to keep its signal active. Stepping off releases it.
Controls Moving platform 4.
Switch 4

Controls Moving platform 5.
Moving platform 1
upper center
At least one of these inputs must be active: Switch 1.
When powered, it moves left; when power is released, it returns.
Moving platform 2
middle left
At least one of these inputs must be active: Switch 2.
When powered, it moves right; when power is released, it returns.
Moving platform 3
lower center
At least one of these inputs must be active: Switch 4.
When powered, it moves up; when power is released, it returns.
Moving platform 4
lower center
At least one of these inputs must be active: Switch 3.
When powered, it moves down; when power is released, it returns.
Moving platform 5
lower center
At least one of these inputs must be active: Switch 5.
When powered, it moves up; when power is released, it returns.
Hanging plank 1
upper center
Its position responds to the weight and position of riders.
Balance on the hanging plank, then jump to the next dry ledge.
Stone box 1
middle center
Walk against its side to push it along its supporting surface.
A box can provide a step, load a counterweighted lift, or hold a pressure plate where the room’s layout allows. Follow the room route before moving it.
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.
