About Thread Sort

Each level in Thread Sort occupies a single, self-contained screen — one spool board to clear before the next canvas detail stitches in. The session flows through discrete puzzles that lock in their progress the instant each spool fills: a completed thread commits to the picture whether you set the game down or roll into the next level right away. Tap a spool to lift its top thread, then drop it onto a matching shade or an empty peg. The action never spills across screens or carries unfinished color-state into the following puzzle, making it a natural fit for a quick clear-your-head break between other tasks. Thread Sort builds its session around these compact, one-board cycles rather than interwoven multi-step chains, so each opening is its own tidy win.

Untangle a colorful mess in Thread Sort, a calming puzzle where you organize threads onto spools by color. Each time you fill a spool with one shade, it automatically stitches part of a lovely picture. The real satisfaction comes from planning your moves to clear the pegs without getting stuck. With its cozy look and smooth gameplay, it’s a perfectly addictive little sort-and-relax challenge.

How to Play Thread Sort

Tap a spool to pull its top thread and lift it clear of the peg.
Tap another spool of the same color to move the lifted thread onto it and stack the color.
If no matching-color spool has space, move the thread onto an empty peg to free up a working spot.
Repeat until each spool contains only one color — every filled single-color spool triggers its own automatic picture stitch.

Game Features

Each level presents a single board of spools — complete the color arrangement and the puzzle ends then.
Filling a spool with one color instantly locks it and stitches a line into the on-canvas artwork.
Empty pegs act as temporary hold slots so players can reorganise thread stacks mid-level.
All threads are 3D and visibly stacked — you see exactly how many layers sit on each spool.
Color groups must fill top-to-bottom: only the outermost thread is accessible on any spool.
The picture builds piece by piece as each single-color spool is completed, giving visual feedback per solved group.

Tips & Strategies

Use an empty peg as a buffer when you need to peel a problematic colour off a spool that blocks access to others.
Plan which colours to finish first: early single-colour spools free up empty pegs for later rearranging.
Keep track of the total thread count per colour — if a colour exceeds the spool capacity you need another empty peg.
Stitch animation plays automatically on fill — you can chain quick taps during the stitch without waiting for it to finish.
Avoid stacking the same colour on multiple spools simultaneously unless you are certain you have enough empty pegs to consolidate later.

Frequently Asked Questions

What happens if I move the top thread to a spool of a different colour?

The move is allowed, but it mixes colours on the target spool, making it harder to isolate a single colour later. You will need to use empty pegs to reseparate them.

Can I move only the top thread, or can I grab a whole stack?

Every tap lifts only the top (outermost) thread from that spool. You cannot grab a stack or pick a thread buried under another.

What counts as finishing a level?

A level ends when each spool on the board contains only one colour. The moment the last spool is filled monochromatically, the picture finishes stitching and the level is complete.

Does the game let me undo a move if I tap the wrong spool?

The official instructions do not mention an undo button. Each tap is a direct action, so plan your selection before tapping to avoid misplacing a thread.
