The Tiny Diamond Vault

Step-by-step walkthrough

1. Raise Fireboy

   Watergirl holds the lower orange plate while Fireboy boards its lowered elevator. Move Watergirl off orange and let Fireboy rise.

2. Cross the right water pool

   Fireboy takes a running jump from the very end of the left bank across the water, collecting red. Jump up onto the right stone shelf, then jump upward before steering left onto the dry end of the lava shelf.

3. Free Small

   Fireboy crosses the lava, jumps onto the dry central ledge and jumps right onto the door shelf. Collect red, jump over the red doorway and continue right. Jump upward onto the high pink shelf and hold pink. Small can now leave the right-hand enclosure.

4. Send Small through the tunnel

   Small walks left along the door shelf, jumps to the central ledge, and walks through the narrow descending passage to the bottom water pool. Hop onto its right bank and hold orange.

5. Collect the lower-right blue diamond

   Watergirl boards orange; Small steps away to raise it. Watergirl crosses the water and jumps onto the right shelf for blue. Return through the pool, hop onto its left bank and board orange again.

6. Send Small to Heavy

   Small holds orange to lower Watergirl, then they exchange places: Watergirl holds orange while Small boards, and steps away to lift Small. Small crosses the pool, hops onto the right bank beneath the low ceiling and drops into Heavy’s enclosure. Touch the white lever to release Heavy.

7. Return Fireboy to the bottom

   Heavy holds orange. Fireboy leaves pink, jumps over his doorway and returns to the lava. Hop over the lava’s right lip and drop onto the right shelf. Take a running jump from that shelf’s far-left edge across the water, then drop onto the lowered orange elevator and walk left.

8. Boost both heroes

   Place Heavy to the right of the tall blue pillar. Jump each hero onto Heavy’s head. Make Heavy hop, then jump from the rising head, going upward before steering left onto the pillar. Leave Fireboy there.

9. Bring Watergirl to the left elevator

   Watergirl drops into the lower water pool and walks left. Jump onto the waiting teal elevator and collect its blue diamond.

10. Climb Small’s stairs

    Small crawls beneath blue and crosses the lower pool. Reach the far-left bank, jump onto the beveled corner of the low stone step, walk up its right slope, then jump left onto the beveled end of the cyan shelf. Walk left to hold cyan and raise Watergirl.

11. Open blue from above

    Watergirl jumps upward before steering right onto the central fan platform. Jump right again to the blue plate, collecting the high blue diamond on the way. Hold blue to open the lower passage.

12. Catch Fireboy on Heavy

    Heavy walks through the opened passage and waits beneath the low red diamond. Fireboy drops left from the pillar onto Heavy’s head, collecting red. Heavy carries him left through the pool to the elevator.

13. Raise Fireboy on teal

    Small leaves cyan so teal lowers. Fireboy jumps from Heavy onto teal. Small follows the low step back up and jumps onto cyan again to raise Fireboy.

14. Power the fan

    Watergirl returns left via the central platform. Jump up and left onto the fan-control shelf, collect blue and hold its orange plate.

15. Collect the left red diamond

    Fireboy jumps from teal to the left shelf for red. Return right to teal, then jump upward before steering onto the left end of the central fan platform.

16. Free the Jumping Friend

    Fireboy enters the powered fan, rises, then steers right onto the high yellow shelf. Collect red and hold yellow until the left enclosure opens.

17. Open the upper purple passage

    The Jumping Friend leaves the enclosure to the right and drops onto the central platform. Fireboy can now leave yellow to the right, drop onto the central upper ledge and walk to purple. Jump for its red diamond, then hold purple.

18. Hand over the fan switch

    Once the yellow panel has returned upward, the Jumping Friend jumps left onto the fan-control shelf and holds the orange plate, allowing Watergirl to leave.

19. Bring Watergirl upstairs

    Watergirl jumps right to the central platform, enters the fan and steers right onto yellow. Leave yellow to the right and join Fireboy on the purple ledge.

20. Collect silver

    The Jumping Friend returns to the central platform, jumps right to the upper central ledge and approaches purple. Jump onto the top of the raised purple panel and walk right into the silver chamber. Collect silver, then jump back left and hold purple.

21. Finish the upper-right blue diamond

    Watergirl passes beneath the raised purple panel and jumps onto the door shelf. Jump over her blue doorway toward the far-right end, collecting the last blue diamond during the jump. Continue onto the high right shelf if needed, then return with another jump over her doorway.

22. Enter the matching doors

    Fireboy passes beneath purple and jumps onto the left end of the door shelf. With all twelve diamonds collected, walk both heroes into their matching doors. Either hero can enter 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.
