Inside these channels sits an array of 120 vibrant, 12mm glass\/acrylic marbles distributed precisely across 7 distinct colors (24 marbles per loop). The core engineering implements a dual-layered central axis, allowing the two main segments of the puzzle to shift and lock into \u003cb data-path-to-node=\"6\" data-index-in-node=\"407\"\u003e10 separate indexing states\u003c\/b\u003e. By rotating the body and sliding the marbles through the shared intersection zones, you scramble the patterns across paths. Your goal is to restore order and re-sort all 7 color groups.\u003c\/p\u003e\n\u003cp data-path-to-node=\"7\"\u003eMolded with a tactile, low-friction finish, this boutique mod is built with optimized internal track tolerances to prevent binding, catching, or friction locks.
