Explanation: The tablet version is for two players, sharing one screen. It is available for iPad and larger screen Android devices (7inch+). You can buy it from iTunes or Google Play. If it's not available for your device from Google Play, you can buy it along with the desktop version for the same price and install it yourself.
The desktop version is for 2 to 4 players, local multiplayer. Buying it from the widget to the right will give you a download link, and we'll throw in the Android version for good measure.
