TriGo

TriGo is a variant of Go game that is played on a hexagonal board and uses stone placement mechanism taken from Connect6. It means that the first player places a single stone and every subsequent move players places two stones per turn. Placing two stones per turn makes game more dynamic and hexagonal shape of the board makes strategies and tactics different from the Go (i.e. in TriGo two "eyes" are not enough for protecting a group of stones).
