A card night with zero gambling

24 July 2026 · First posted on LinkedIn · Card Fever ↗

Poker night, blackjack, a fast hand of rummy, with zero gambling.

I just launched Card Fever, ten classic card games in one app for iPhone, iPad, and Mac.

Wild Eights, Hearts, Rummy, Go Fish, War, and President, plus the dealer games everyone knows: Blackjack, Texas Hold’em, Baccarat, and Five-Card Draw.

Here is what makes it different. The dealer and showdown games have no betting, no chips, and no money. You win by winning rounds, first to the target takes the match. It plays like a real card night, but there is nothing to wager and nothing to cash out, so it is something you can actually hand to a kid.

For me, the build was a way to test what I am capable of. Card games make a great proving ground. Each one is small enough to finish but complete enough to exercise the whole stack at once: rules and game state, an opponent that has to actually be smart, real-time networking, saving and replaying, and a screen that has to feel good in the hand. One game tests a slice of that. Ten games of different shapes, from shedding to trick-taking to melds to a poker showdown, test all of it.

The rest is leverage. All ten games run on one engine, one game screen, and one Wi-Fi layer, so each new game inherits the hard parts for free: clever bots that bluff, pass-and-play with a PIN to hide your hand, local multiplayer with live chat and a session leaderboard, an optional coach that shows the odds and a plain reason, and full replays of every finished game. By the tenth game I was adding rules, not rebuilding foundations, and it still shipped feeling finished. The games are what you see. What I was really measuring is how far one person can get when the architecture does the heavy lifting.

A few principles I held to:

  • Free. No ads, no in-app purchases, no accounts.
  • Local-first. It works fully offline and your game history stays on your device.
  • One codebase on iPhone, iPad, and Mac, with light and dark mode, themes, and adjustable text size.

If you have a family that argues over card games, I would love for you to try Card Fever and tell me which game your table fights over first.

Card Fever is on the App Store.
