Founded in 2015, Intrism designs and makes build-it-yourself 3D wooden marble maze puzzles at its small production facility in Columbus, Ohio. Its laser-cut plywood kits are meant to be assembled without glue or tools, then played as challenging mazes and displayed as finished sculptural pieces. Intrism handles design, sourcing, manufacturing and marketing in-house, and says its products are made in the USA with carbon emissions offset for every puzzle.
