The Delta (2-Color)
A snappy, tactile mechanical puzzle that changes form as you play.
Description
The Delta with (2 colors) is an approachable mechanical brainteaser with surprising depth. It features the same tactile, satisfying action as my other designs — but with a completely new twist. Depending on the position of the rotating core, the puzzle transforms between a single continuous track and two separate tracks. Planning your moves becomes a true mental exercise as you work to untangle and sort the colors.
Cycle the beads through the single or double tracks, and rotate the colored dial to scramble or solve.
Designed to sharpen focus, spatial reasoning, and sequential problem-solving skills, The Delta makes a perfect gift for engineers, programmers, mathematicians, and anyone who enjoys deeply satisfying technical challenges.
Objective
Difficulty Level: 4/10
3D printed in PLA, a durable plant-based thermoplastic. Keep away from intense heat and don't store in direct sunlight.
⚠️Safety notice: While balls remain securely in tracks under normal use (and our thorough drop testing), deliberate misuse (e.g. prying with tools) may dislodge them, creating a choking hazard. Not suitable for children. Ages 14+.
