In September 2019, a team led by game developer Matt Wilson prepared a 20-foot-wide, walk-on version of Simon for a planned OneRedmond tournament at Redmond Downtown Park. The giant game turned the familiar light-and-tone memory challenge into a team activity: players stood on oversized buttons, and sensors detected which button carried the team’s greater weight. The event preview described a possible Guinness record attempt, not a confirmed record.
What the 2019 preview announced
GeekWire reported on September 7, 2019, that an all-ages Simon tournament was planned for the following Friday and Saturday at Redmond Downtown Park. Organizers expected more than 30 teams of eight, representing companies and organizations from around the region. The project was intended to activate the community through full-body play. OneRedmond executive director Kristina Hudson said, “Part of our mission is to bring some soul to the Eastside, some creative flair, some fun.”
This was a preview of a planned event, not a current listing. The report does not establish what ultimately happened at the tournament. GeekWire’s September 7, 2019 report is the source for the event and construction details below.
How the giant Simon game worked
Simon, introduced in 1978, challenges players to repeat a growing sequence of lights and tones. Wilson’s custom version made that individual memory game physical and collaborative: instead of pressing small controls, teammates stood on large illuminated buttons and had to coordinate their movements.

Weight, not hand presses, selected a color
The installation was 20 feet wide, with each button measuring 10 feet across. Load cells beneath the buttons sensed the combined weight on each one. To select a color, a team shifted the majority of its weight onto the corresponding button. That design made communication and coordination central to play.
Electronics and construction
According to GeekWire, a Raspberry Pi ran the main game logic and communicated with an Arduino Mega, which managed the load cells and buttons. The build also used more than 10,000 LED lights, two kilometers of steel in its subframe, plywood, a car amplifier and four large speakers. An original Simon game from the early 1980s had been converted into the start button.

GeekWire reported that the project cost more than $20,000 and weighed well over 2,500 pounds. Those are figures from the 2019 article, not independently audited measurements. The team built the installation in eight pie-shaped sections, each requiring a special set of wheels for moving it. Wilson summed up the scale of the engineering challenge: “You very quickly realize all the complexity in building one of these things at this scale.”
Who built it, and why make Simon a team game?
Game developer Matt Wilson, who had worked at Microsoft and founded Detonator Games, was asked whether he knew people who could build a large game for a OneRedmond event. He and collaborators worked through the nonprofit Northwest Art Center in Duvall, Washington. GeekWire named John Hawkins, Lloyd McCracken, Emily McCracken, Paige Carter and Wilson’s son Aidan as part of the build effort; Aidan handled much of the design, fabrication and programming.

The oversized format changed the social dynamics of Simon. A team had to listen, remember the sequence and decide together where to place its weight. Wilson’s advice to prospective players was practical: “Decide who the leader is and come up with a strategy.”

The GeekWire preview said the installation “could break” the Guinness World Record for “World’s Largest Electronic Memory Game.” It did not report that Guinness verified the attempt or that a record was set. The tournament’s final outcome and record status therefore remain unconfirmed by that report.
