About this game

Havana is a card game of building and trading for 2–4 players. Choose roles, construct buildings, and accumulate victory points. The AI provides a solid single-player experience while multiplayer connects players peer-to-peer with no accounts required.

Status: Playable. AI tuning and minor UI refinements are in progress.

The web build runs in any modern browser on desktop or mobile. Desktop builds aren't signed yet — your OS will warn the first time.

First-time install help (macOS / Windows / Linux)

macOS

Double-clicking the app after dragging it to Applications may show: “‘Havana’ can’t be opened because Apple cannot check it for malicious software.” Two ways around it:

  1. Right-click → Open. In Applications, right-click (or Control-click) the app icon and choose Open. A new dialog appears with an Open button — click it. macOS remembers the choice.
  2. If right-click-Open doesn't work (newer macOS versions are stricter): go to System Settings → Privacy & Security, scroll to Security, and click Open Anyway next to the blocked app.

Terminal shortcut: xattr -d com.apple.quarantine /Applications/Havana.app strips the quarantine flag.

Windows

Running the .exe shows a blue SmartScreen dialog: “Windows protected your PC”. The installer isn't signed with an Authenticode cert.

  1. Click More info at the top of the dialog.
  2. A Run anyway button appears below the message — click it.

Linux

AppImage just needs the executable bit:

  1. chmod +x Havana.AppImage
  2. ./Havana.AppImage

If you see a sandbox error on older distros, add --no-sandbox.

Which version should I use?
  • Desktop: Use the download matching your OS. The Mac build is universal for Apple Silicon and Intel.
  • Web: Best for a quick game on any modern browser, especially on a device you don't want to install software on.
  • iPhone / iPad / Android: Open the web version in Safari or Chrome, then add to your home screen for the best full-screen experience.
