Seven Seas

A sea consists of drops. There are 6 seas to start with, all just have one drop. When you touch an adjacent drop to the sea, the drop joins the sea and it takes the color of the drop. Both players can add drops of both colors. A sea will close with the 7th drop. It then is conquered by the player with the color of the last drop that joined it. The player who first owns 7 seas wins. The game is over when the 7th sea has closed or when no further drop is left to enter a sea. In the latter case there is no winner.
