12 Tiles is a free puzzle game you can play in your browser. It works best on a touchscreen device, but runs on any modern browser.

The game board consists of 12 numbered tiles. The goal of the game is to arrange them in order, but you can only move tiles by creating sequences of 3 or more neighboring tiles with increasing numbers. The in-game tutorial will show you how it works.

To install the game as an offline iOS or Android app:

• iOS: Start the app, then tap the "action button" (the box with an upward pointing arrow), then choose "Add to Home Screen". Tap the new icon to start the application. The first time you start it you need to be online, after that it works offline.
• Android: Start the app, then tap the "menu button" (the three dots on top of each other), then choose "Add to homescreen". Tap the new icon to start the application.

The game looks best in portrait orientation, and the tutorial in landscape, but turning your device is completely optional.

Start the app!
