Energy and turns
Attempts use energy and puzzles have turn limits. Reset an active attempt for a free retry. Where available, completed rewarded ads provide the stated benefit.
In development for iPhone
Connected rails. Careful moves.
A mechanism you learn by doing.

Actual development build




Captured from the native iOS development build. Screens and final release details may change.
01 / The mechanism
Every rail has a target. A tap moves one rail forward—but its connections can move the others, too. Find the sequence that brings everything into place.
The labels tell you which rails move together.
Later puzzles add interlocks. Free one rail before you move another.
Line up every rail with its target. Undo or reset when you want another approach.
Each click advances a marker one notch, wrapping after the fourth position. The gold rings are the targets.
Interactive rule demonstration · not a capture of the app. No energy, ads or purchases.

A daily mechanism
Alongside the 300-puzzle journey, a daily mechanism offers another connected puzzle to work through. Find a fresh arrangement each day and work out the sequence that brings it home.
Your progress stays on your device. There is no game account or cloud sync in the current game.
03 / Material studies
Jade and ivory. Burnished copper. Midnight atelier. Three finishes give the workshop a different feel.
Jade is the original finish. Copper and Midnight are planned optional in-app purchases; the collection marks locked finishes clearly.

Attempts use energy and puzzles have turn limits. Reset an active attempt for a free retry. Where available, completed rewarded ads provide the stated benefit.
Planned optional digital purchases will use Apple’s in-app purchase system. Prices and benefits are shown before purchase. Eligible purchases can be restored in the shop.
Sound and haptics give each move a little weight. Their controls are in the game’s settings.
