Theorysonic Pyramid is a home video game console developed by Theorysonic. It is the first home video game console to be based on TS-UGOS as well as a last game console before Theorysonic begins its 18-year hiatus as the first-party developer.



Theorysonic Pyramid was launched on January 4, 2000, in El Kadsre with the price of $349. It has 4 player controllers, CD-ROM, DVD-ROM and a USB output for saving data, downloading content, playing multimedia and backup, while its controller has two analog sticks, a digital pad, four action buttons, two action triggers, built-in speakers and a built-in Page orientation color LCD screen. The Pyramid can also play Musicards in the card slot on the left side of the console and play Videocards as well, although it required the dongle in order to play Videocards. The Pyramid is the first and only game console to gain access to the web with the customized version of the Star Web browser built-in the console. The Pyramid's firmware is based on TS-UGOS, therefore it can play TS-UGOS games.

Theorysonic Pyradesk

Theorysonic Pyradesk is a unproduced two-in-one TheoryDesk and Theorysonic Pyramid which Theorysonic planned to release alongside the Pyramid in January 2000 with the retail price of $650. Theorysonic cancelled the Pyradesk in November 1999, citing fears that it would become the commercial flop like the VRBuddy due to its power issues and it would dilute their marketing for TheoryDesk VM.


The Pyramid was initially a success when it was released in El Kadsre in January 4, 2000. But when PlayStation 2 was released in the country two months later, the PS2 was a instant success, overtaking the Pyramid in terms of sales less than two months after release. The PS2 sold roughly ten times more than the Pyramid. The PS2 craze made it virtually impossible for the Pyramid outshell PlayStation 2 as well as the Xbox and Nintendo Gamecube. The Pyramid's decline has also something to do with Theorysonic being more focused at making Portosic devices as well as TheoryDesk and TheoryBook devices.

While the Pyramid was sold well in the El Kadsreian, American and Australian markets, it received poor sales in Japanese and European markets due to competition with other game consoles.

In 2006, Theorysonic announced the Pyramid would be a last game console due to lackluster sales, instead of focusing on work Portosic, TheoryPhone, and TheoryTablet devices and TS-UGOS computers for gaming. Over 17 million units sold worldwide during its lifespan. The console finally discontinued on April 30, 2011.
