Geomag is a magnetic construction toy. The original toy comprised bars with a magnet on each end all attached by a magnetic plug, and nickel-coated metal spheres. Magnetic forces hold the bars and spheres together, creating the possibility for many constructions. Invented and patented by Claudio Vincetelli in May 1998, production is currently undertaken by Geomagworld SA at the production facilities in Novazzano, Switzerland. Product lines have been added to the original model, growing the Geomag range of construction toys. Since the introduction of the 2009/48/EC law on 20 July 2013 restricted the content of nickel in toys, Geomag has re-modelled the spheres with a bronze alloy coating, in order to comply with the new regulations.

At 2015, most T puzzles come with a leaflet with additional figures to be constructed. Which shapes can be formed depends on the relative proportions of the different pieces.

The PlasmaCar is a plastic ride-on toy car designed for children,, made popular by Canadian toy distributor PlaSmart.

It harnesses the natural forces of inertia, centrifugal force, gravity, and friction in order to drive the car forward and backward. It does not require a power source such as batteries, fuel, pedals, or gears - it simply runs on the child's ability to wiggle the steering wheel. It can be operated indoors and/or outdoors, though it works best on a smooth, flat surface.
The 36 Cube is a three-dimensional sudoku puzzle created by ThinkFun. The puzzle consists of a gray base that resembles a city skyline, plus 36 colored towers. The towers come in six different colors and six different heights. The goal of the puzzle is to place all the towers onto the base so as to form a level cube with each of the six colors appearing once, and only once, in each row and column. The 36 cube was invented by Dr. Derrick Niederman, a PhD. at MIT. He came up with the idea while writing a book on whole numbers, after unearthing an 18th-century mathematical hypothesis. This supposition, the 36 officer problem, requires placing six regiments of six differently ranked officers in a 6-x-6 square without having any rank or regiment in the same column. Such an arrangement would form a Graeco-Latin square. Euler conjectured there was no solution to this problem. Although Euler was correct, his conjecture was not settled until Gaston Tarry came up with an exhaustive proof in 1901.
