Checkers on a wooden 3D board. Play against the computer at four levels of difficulty, against a friend on the same phone, or against a friend anywhere using a room code.
Coming soon to Google Play and the App Store.
Questions, problems or ideas: write to checkers@nordictulip.com. The game has no accounts, so there is nothing to log in to or recover; reinstalling resets it.
