One Day Games

Take your tabletop game digital

Faithful digital companions to physical games — a love letter, not a copy.

You made the tabletop game. One Day Games makes the version people can play in five seconds, anywhere — instant play, no install — and it points them straight back to your table.

Founded by CJ Connoy — 32 years in AAA games (Call of Duty: Black Ops, PlayStation/SIE).

Two companions shipped and live — for two different tabletop studios.

Featured work

Two tabletop games. Two live companions.

Two different studios have handed me their games. Both companions shipped — faithful to the original, built to drive discovery and point players straight back to the real thing.

What's Under Your Bed?

Alex Mackey and Mike Szalajko at Lethal Chicken Games handed their monsters to me. Their tabletop horror game got a faithful digital companion — match your Monster Cards against the clock before the thing under the bed comes out for you.

Big Discoveries

Trash Dice

Big Discoveries handed me Trash Dice. Their push-your-luck dice game became an instant-play companion — roll to win, dodge the bin, and unlock new dice as the round wins stack up. Same craft, different studio's IP.

Studio

Build small. Ship often.

32 years in AAA games, including shipped Call of Duty titles, building a 60-person hybrid team at Deviation Games, and founding design leadership at SIE’s Dark Outlaw Games.

One Day Games brings that craft to your game: CJ personally interprets your physical game and builds its digital companion, start to ship — no account team, no hand-off.

I don't just produce — I design and build. As Founding Senior Lead, Design at SIE Dark Outlaw, I started the co-op prototype that became the foundation of the studio's main AAA IP. The senior person hands-on, interpreting and building — the same approach behind every ODG companion.
Upkeep is increasingly automated. ODG runs production checks that can detect issues, make bounded repairs, validate results, and ship or promote fixes with an audit trail. Creative and feature work stay human-led.
