Nonaga

Nonaga has a hexagonal playing area composed of 19 rings, with each player having three pieces that start in alternating vertices around the hexagon. On a turn, a player must do two things, in order: Move one of their pieces in a straight line up to the end of the board or up to colliding with another piece Move one of the exterior empty rings to another location on the playing area where it touches two rings. Whoever first manages to connect their three pieces wins!
