History
Gakken is perhaps originally known for producing Denshi blocks and packaging them within electronic toy kits such as the Gakken EX-System, as far back as the 1970s. One of their original lines, the EX-150, was reissued in 2002, and was so popular as to inspire an expansion pack.

In 1981 Gakken released "Super Puck Monster", a tabletop LCD arcade game that resembled Pac-Man. Coleco also licensed "Super Puck Monster" and released it as an official Pac-Man game. Gakken also released an official Dig Dug game, unlike "Super Puck Monster" this game was only sold in Japan and never exported.

In October 1983, the Gakken Compact Vision TV Boy console was released.

Since 1993 Gakken has been publishing monthly logic puzzle magazines under the name Logic Paradise.

Gakken manufactured an 4-bit computer known as the GMC-4.
