Next Floor

This is a multi-layer ball maze. Try to get the steel ball out of the maze. The ball interacts with both floors and ceiling, so it is quite a challenge to see the path. This makes it a fun puzzle.

Gear Maze 2x2

This is a maze built from four connected 23-teeth gears. Move the ball from the start (circle) to the finish (triangle) by tilting the puzzle and turning the gears.

Gear Maze 3x3

This is a gear maze built from nine connected 17-teeth gears. It is bigger and harder than the 2x2.

Gear Maze 2S

This is a two-sided gear maze built from four connected 17-teeth gears and a large gear ring. It is very hard, as the ball hops to the other side every time.

Fractal Jigsaw

This is a 11-piece jigsaw puzzle, but also a diasappreaing act. Despite their large size, it is hard to distinguish the pieces, that seem to disappear as soon as you dropthem in. Now you see it, now you don't!

Pachinko

Drop the "X" and "O" coins into the two slots in such order that all "O"-s and "X"-s end up together. The two-splitter and three-splitter mechanism has baffled some of the smartest brains in the world. This puzzle is very hard to solve.

Topsy Turvy

This puzzle is based on the M12 puzzle proposed by prof. Igor Kriz in Scientific American. The puzzle features a 12-splitter, similar to the ones in Pachinko. Being based on group theory, this puzzle is extremely hard.
