CardMonster Shows Tabletop Lab Cutting Card Game Prototyping To Under 15 Minutes
CardMonster is selling the freed-up development time as creative headroom rather than a cost cut, and its own numbers put the claim at an 18-month prototyping cycle trimmed to 3.
Reporting from 1 source: 4Gamer.net.
At Tokyo Game Show 2026, CardMonster ran a stage demo of its Tabletop Lab tool at the 4Gamer booth. A natural-language prompt for a four-player game about running a TGS booth produced a playable prototype in under 15 minutes. CardMonster says prototyping time fell 83 percent, from 18 months to 3 months.
The demo prompt asked for a four-player card game about running a Tokyo Game Show booth, where the player who draws the most visitors wins, with play time of about 10 to 15 minutes. While the tool generated the prototype, moderator Shun Harashima took questions for the two CardMonster staff on stage, CEO Pine Sohn and developer Bum-Jin.
CardMonster develops analog card games and has released titles using IP from companies including Disney and KRAFTON. The stated mission behind the tool is letting designers concentrate on creation, and the company wants the recovered time spent on planning and other creative work.
