Step-by-step walkthrough
Send Jumper through white
Fireboy holds the white floor button. Jumper jumps towards the lower white portal from its left side. On arrival, move right along the middle ledge, jump up to the narrow upper step and cross left to green. Fireboy can leave white once Jumper is upstairs.
Drop the right crate
Jumper returns across the upper step, drops onto the right-hand shelf and stands to the right of its crate. Push the crate left off the shelf into the lava, then jump back to the shelf.
Collect the lava-side red diamond
Fireboy follows the crate through the lava, pushes it towards the right bank and jumps onto it. Jump again beneath the floating red diamond. Move to its right and push it left across the sloping bank. Stop beside the lower white portal, leaving room to jump around its small pedestal.
Deliver the bowl crate
Jumper returns to green and lowers its lift. Step into the lift shaft, then move right onto the shelf below before the lift rises. Push the second crate right down into the central bowl.
Return Jumper to green
Jumper jumps out of the bowl onto the left shelf. Return to the bottom floor by jumping left over the small lip. Watergirl holds white while Jumper repeats the portal journey, the right ledge jump and the walk to green.
Collect Fireboy’s bowl diamond
Fireboy jumps onto the lower crate, waits until his head clears the pedestal and steers left onto it. Enter white and move left into the bowl. Jump beneath the red diamond.
Climb out using the bowl crate
Push the bowl crate left. Jump onto it, then jump left onto the sloping wall and again onto the left shelf. Walk onto the lowered green lift. Jumper leaves green to raise Fireboy, who then stands on green himself.
Send Watergirl to the right blue diamond
Watergirl uses the lower crate to reach the white pedestal. Jumper returns to the bottom floor and holds white to send her through. Once she arrives, Jumper leaves white so Watergirl can move right safely. Jump beneath the right-hand blue diamond.
Collect Watergirl’s bowl diamond
With white off, Watergirl walks left into the bowl. Jump onto the left crate beneath the blue diamond, then climb out over the left wall. Board green while Fireboy holds it down; Fireboy steps away to raise her.
Weight white and return Jumper
Jumper moves to the right of the lower crate and nudges it left onto the white button. Jump through white, then out of the bowl and onto the green lift. Fireboy lowers and raises green for him. Jumper walks to the pale blue button on the middle ramp.
Collect the high red diamond
The pale blue button lowers the top lift. Fireboy climbs the middle ramp, jumps to the narrow right-hand step and crosses to the far-right upper ledge. Jump beneath its red diamond, then return to the narrow step.
Board the top lift together
From the narrow step, jump up before steering left onto the lowered top lift. Leave space for Watergirl to follow the same route. Jumper leaves the pale blue button to raise both heroes.
Open the ceiling portals
Jumper crosses left to hold the blue button. Each hero jumps into the upper portal in turn. After appearing on the left, steer down the left diamond column: Fireboy collects red, Watergirl collects blue, and either collects the shared diamond.
Collect the last low blue diamond
Both heroes step onto the green lift. Jumper leaves blue and holds green to lower them to the left shelf. Watergirl jumps over the small left lip and drops through the last blue diamond. Steer back towards the middle before landing if you want to wait outside her door.
Return to both doors
Fireboy drops from the left shelf and returns right to his red door. Watergirl enters the blue door on the lower left. All nine diamonds are collected; either hero may finish first.
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
Count the ring-marked diamonds still visible. All 9 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.
