The board game Tsuro had a rocky road, leading to several editions published before Calliope got the rights to the game. Since then, they have not only supported the game but created a sequel, Tsuro of the Seas, with an expansion. Now they are going to bring the Tsuro experience to mobile devices, while keeping the board game experience intact. I got a chance to take a look at an early version at GenCon, and I have to say that I am impressed. For more info about Tsuro, take a look at the Tsuro home page.
