About

Sutda · A Screwcap Games, LLC property · Updated 25 August 2026

Sutda is a two-player Korean flower-card game — hwatu, the same 48-card deck used for Go-Stop, dealt two at a time. You get two cards, you bet or you fold, and the hands have names rather than numbers: Gwang-ttaeng, Ali, Sae, Gu-Pi. It is one of the fastest gambling games ever designed, which is exactly why it makes a good game about reading a person rather than reading a hand.

There is no money in it. All stakes are virtual, they cannot be bought, cashed out or transferred, and the AI opponents were built from self-play rather than from anything you did. What you are practising is the read — when a bet means strength, when it means someone wants you to think so, and how much that difference is worth.

The opponents have their own tells and their own nerve. Jee bluffs more than the arithmetic justifies. Learning who you are sitting across from is most of the game, and the hand-explanations after each round exist so that losing tells you something.

How it pays for itself

Advertising on the free tier — on menus, between hands and on end screens, never during a live hand — plus an optional one-time ad-free unlock. That is the whole business model for this game. Which analytics and advertising vendors we let near you is listed by name in the Privacy Policy; if a tool sets a cookie, it is in there.

Who makes it

Sutda is made by Screwcap Games, LLC, a small independent studio in Walworth County, Wisconsin. We build games about judgment under uncertainty — monetary policy, commodity markets, household finance — and a few card and domino games that are just games. The rest of the catalogue is at Screwcap.Games.
