Thread Sort Puzzle 3D is a sorting puzzle that features objects made of threads. The player's goal is to disassemble these objects by pulling, unraveling, and sorting threads into color-matched boxes. This game most closely matches popular nail, pushpin, screw and other hardware sorting games like Screw It!, Get a Screw: Puzzle!, and Colors Pins.
After the player makes a colored thread selection, the game auto-pulls the thread from the object and wraps it around a spool in a container. If the color doesn't match, it spools the thread in five holes below the containers. If the player fills the fifth spool, they lose. They must then view an ad to continue or restart the level.
Otherwise, the player continues this process until no more threads remain. The game rewards them with coins and then unlocks the next level and object. At any time, they can zoom in on an object by using a lower-right corner zoom slider.
Thread Sort Puzzle 3D allows the player to work faster by unlocking two additional containers when they view videos. It also provides them with three boosters. The player can add a hole, transform a box to accept any color, and clear the threads from all holes.
