Trugo

Trugo is a board-less tile-laying game with Go-like capture. It has a "Waxing" phase, in which tiles and chips are added, and a "Waning" phase, in which chips are moved or tiles are removed to capture the chips they touch. Trugo can be played with 36 Mambo tiles (plus 2 colors of chips, 25 each) by treating red and blue segments as equivalent.
