- Order of the Sinking Star last gem is found by mastering block pushing and gem-displacement logic in the basement overworld.
- Core rule: You can push any block or gem you are facing, including chained objects touching it.
- Look-ahead: Some squares only activate when paired gems are placed together, so plan before committing.
- Total goal: Collect all 20 gems, return them to the pedestal, and unlock the story revelation.
- Warning: One wrong push can trap you, so back out and re-route instead of forcing a bad position.
Understanding the Last Gem Puzzle
The giant overworld level in Order of the Sinking Star is a sprawling multi-floor puzzle hub where gems are trapped behind blocks, colored barriers, and activation squares. The last gem is almost always one that looks "stuck" — buried behind green barriers, blocked by movable objects, or sitting in a section that only becomes reachable after other gems are placed.
Here's a full playthrough showing how all 20 gems (including the final stubborn ones) are collected:
Video Highlights:
- How chained block-pushing clears the path to trapped basement gems
- How activation squares pair gems before they turn blue
- The exact trick for dislodging the final gem blocked behind a green barrier
- What happens story-wise when all 20 gems are returned to the pedestal
The lit squares on the floor won't activate until every gem inside that grid square is placed. If a square stays dim, a neighboring gem in the same zone is still missing — placing a lone gem there now is wasted, so move on and find its partner first.
Core Mechanics You Must Use
Three mechanics govern nearly every gem in this level, and the last gem usually requires all three working together.
| Mechanic | How It Works | Gem Relevance |
|---|---|---|
| Face-to-Push | Push any block or gem you are looking at | Dislodges gems trapped behind blocks |
| Chain Pushing | Pushed objects move everything touching them | Clears multi-block pileups |
| Activation Squares | Turn blue when all gems in the zone are placed | Unlocks portals and barriers |
| Teleport Power | Moves you exactly two spaces | Crosses gaps to isolated gems |
| Red Blocker | Requires red power to remove | Gates certain basement gems |
| Block Destruction | Yellow power breaks blocks | Opens sealed rooms and paths |
Face-to-Push
- Direction matters: You push what you face
- Can also push gems directly
- Useful for repositioning blockers
Green Barriers
- Pass through when clear
- Removing the wrong gem can trap you
- Keep an alternate gem ready to trade out
Portals & Teleports
- Unlocked via activation squares
- Delete portals by re-activating remotely
- Two-space hop reaches ledge gems
Pushing a gem into a new section without a way back can strand you. If you end up "just trading gems" and getting stuck, exit the area — the block layout often resets, letting you re-approach from a better angle.
Step-by-Step: Claiming the Last Gem
Sweep the Basement First
Collect every freely reachable basement gem. Note the three or four that are visibly trapped — these need block-pushing solutions. Skip any dim activation square for now.
Clear Blocked Gems with Chain Pushes
Stand facing the outer block and push. Chained pushes ripple through every touching object, freeing gems buried behind multi-block walls. Re-check rooms that previously dead-ended.
Resolve the Trapped Green-Barrier Gem
For the gem locked behind the green barrier, push everything systematically in one direction — pushing the whole cluster left (or down) eventually exposes the gem's path. Then destroy or displace the mover-block that shifted it.
Use Remote Activation for Portal Gems
Some gems sit behind portals. Carry the power to a zone with an activation point, trigger it there, return, and the portal dissolves — freeing the gem.
Return All 20 Gems to the Pedestal
Place every gem in the pedestal. This triggers the story scene about the buried pocket realm, Lurca's origins, and the egg-shaped realm marker — and opens the path toward the mirror aisles.
Track your total out loud or on paper as you collect. The final count must read 20. If you're stuck at 18 or 19, check the bottom-middle of the overworld map — a hidden gem is commonly missed there.
After the Last Gem: What Unlocks
Returning all gems isn't just a completion checkbox — it gates meaningful content.
| Unlock | Requirement | Notes |
|---|---|---|
| Story Revelation | All 20 gems placed | Explains the buried pocket and Lurca's origins |
| Mirror Aisles Access | Post-pedestal | Tricky reflection puzzles with a moving-block twist |
| New Fast Travel Points | Explore post-unlock | Expands the overworld map significantly |
| Blocked Mirror Route | Later demo progression | Mirror stays blocked until related level is cleared |
| Demo Boundary | Eastern territory | "Not accessible in demo" — full game unlock to come |
The demo reportedly contains 105 levels, and the full game is planned to fuse all regional mechanics and character storylines together.
Last Gem Completion Checklist:
- Collect all freely reachable basement gems
- Free every gem trapped behind pushable blocks
- Activate paired squares so they turn blue
- Solve the green-barrier gem displacement
- Return all 20 gems to the pedestal
Wishlist the game when prompted at the demo boundary — the NPC gag about "setting it upon thy list of wishes" is the developers' way of pointing you toward the full release.
FAQ
Q: How many gems are in the Order of the Sinking Star overworld level?
There are 20 gems total across the basement and upper floors. Collecting all 20 and placing them on the pedestal triggers the major story revelation and opens the next area of the demo.
Q: What if I pushed a block somewhere and now the gem is unreachable?
Exit the area and re-enter — pushing objects into dead configurations is common, and leaving typically resets the layout so you can approach from a better angle. Avoid forcing a push when you can't see a clear exit path.
Q: Why won't my activation square turn blue?
Squares only activate when every gem within that grid zone is placed. A dim square means a partner gem elsewhere in the same zone is still missing. Find and place that gem first before returning.
Q: Can the last gem be pushed directly?
Yes — gems themselves can be pushed when you face them. For the final green-barrier gem, keep pushing the surrounding cluster in a consistent direction until the gem's path opens, then displace the mover-block blocking it.
