About This Demo

Syncline is a puzzle game where your piece is a whole line of cubes. You tip it end over end across the board, one move at a time, until a cube touches every goal. Lying flat, the line rolls along the ground. Stood on end, it can climb. If you played Bloxorz or Cuboid, the rolling will feel familiar. The difference is that this piece can come apart and be put back together.

Climb up, then find a way down

Stand the line on end next to a ledge and roll, and it tips up onto the higher ground. Cubes that don't make it up stay below. Those loose cubes aren't lost. Roll so one sits in line with the end of your line and it joins back on. That's also how you get down again: a loose cube waiting on lower ground is your way back down.

When the line breaks

Roll into a wall and the line breaks. The cubes that can move go with you, and the rest stay where they stopped, a duller blue, waiting to be collected. A short line fits through places a long one can't, and some goals need every cube you have, so knowing when to split and when to gather up is a big part of the game. Your line never rolls off into empty space, so you can't lose a cube to a careless move.

Turn the camera

The camera turns in quarter steps, and your controls turn with it. The angle matters for more than the view: when the line breaks, where you're looking from can change which cubes stay with you. Pan and zoom the camera to look over the whole level before you move.

Blocks that take your cubes

A Destructor destroys any cube that touches it, from any side, and your line splits where that cube was. A Duplicator turns the cube that touches it into another Duplicator, so every touch leaves one more of them on the board. Neither one wears out.

Ground that changes under you

Fragile ground carries you once and breaks as soon as you roll off it, so the order you cross it in matters.


Cover every cell of a Trigger and blocks elsewhere on the board appear or disappear. Some levels also lock the goal until you've touched every Subgoal.

AI Generated Content Disclosure

The developers describe how their game uses AI Generated Content like this:

Syncline is developed by me — AI tools were used to assist with parts of development, including code, some text content (UI copy, tutorial hints, level descriptions, store page copy), localization/translations, and some audio. All such content was directed by me and reviewed/edited before being included. No content is generated by AI at runtime — everything players see, hear, and play is fixed at build time.
