Tsuro of the Seas has a gripping Nautical theme and introduces Daikaijus - sea monsters! The game still challenges players to drive their opponents into each other or off the board whilst simultaneously extending their own route. The slightly bigger 7 x 7 grid board takes centre stage and players are dealt a hand of tiles (with two, twisting lines on it) and also places their marker on the grid. In turn order players place a tile from their hand onto the board and moves their token as far as it can go along the line until it is stopped by an empty space. If the token reaches the edge of the board or collides with another player's token that player is out of the game. The aim of the game is to be the last player left with a token on the board.
