Fourfold

The Fourfold

A game console you talk to. Say what you want to play, and it builds the game.

Description

The Fourfold is a handheld game console that makes its own games. You hold the knob in, say what you want to play, and the console builds it. When the game is ready it lands on your shelf next to the others. If you want it different, you pick the game and say what to change.

It has a knob, two buttons, a touch screen, two microphones, and a speaker. Every one-player game is made to be playable with just the knob and one button.

The console is a working prototype and is still being built. Fourfold publishes a dated build journal, including the things that broke.

History

Where it came from

Fourfold has built electronic conference badges since 2017. The most recent, for THOTCON 0xD in 2025, had a screen, a touch wheel, and mini-games. The Fourfold is the same kind of object, built for games first.

The first three weeks

Development started on September 6, 2026, on an Espressif development board. Two days later the full loop worked for the first time: say a sentence, get a game. The knob and buttons went in on September 25, in a 3D-printed case.

Features

  • Say what you want to play and the console builds the game.
  • Change any game by talking to it.
  • Pick how much game you want: about 3 minutes for a sketch, 12 for a whole game, 30 for the full thing.
  • Keep playing other games while a new one builds.
  • Every new game is played by automated testers before it reaches the shelf.
  • Your shelf of games works with no internet.
  • One knob, two buttons, and a touch screen.
