Spiderly is a Progressive Web App (PWA), which means your browser automatically caches the game, card images, and all assets on first load. From that point on, the game runs entirely on your device — no internet connection needed. You can also install Spiderly directly to your home screen on iOS, Android, or desktop for a native app experience: launch it instantly, play in fullscreen, and never need a browser tab. Your game progress, settings, and statistics are all saved locally, so nothing is lost when you go offline. It's the perfect companion for commutes, travel, or anywhere your connection is unreliable.
How Offline Play Works
Spiderly uses Progressive Web App technology to enable offline play after your first visit. When you load the page for the first time, your browser automatically downloads and caches the entire game — HTML, JavaScript, card images, sounds, and styles. On subsequent visits, the cached version loads instantly from your device storage, with no need to fetch anything from the network. This means the game works on airplanes, subways, remote cabins, or any location without Wi-Fi or cellular data. Your game state, statistics, settings, and achievements are all stored locally in your browser, so nothing is lost when you disconnect. If you do have a connection, Spiderly checks for updates in the background and applies them the next time you reload.
Installing Spiderly on Your Device
For the best offline experience, install Spiderly directly to your device. On Android, open the site in Chrome, tap the three-dot menu, and select "Install app" or "Add to Home screen." On iOS, open the site in Safari, tap the Share icon, and choose "Add to Home Screen." On desktop, click the install icon in the address bar of Chrome or Edge. Once installed, Spiderly launches like a native app — in fullscreen, with its own icon, and without a browser tab. Installed PWAs also tend to load faster and survive device restarts better than a browser tab. Installation is completely optional: you can always play offline in the browser without installing anything.
