Battleships is a well known traditional board game for two players which dates from World War I. Though, the game has several digital version implementations, they are affected by similar major drawbacks such as fairness and a trust model that relies on third party. In this paper, we demonstrate how to implement a fair, resistant to denial-of-service, where the honest winner earns the deposit money immediately. The game is built on a permissionless Blockchain that supports Turing complete smart-contract computation.
