Fivalath is a derivative of Yavalath (like Squava). It is recommended to be played on a 10x10 square board, although other sizes are allowed (no less than 8x8). 2 players (White and Black) alternate turns placing a pawn of their colour on an empty space of the board. Players strive to make a line of 5 pieces of their colour, but lose if they make a line of 4 before doing so. Lines can be orthogonal or diagonal. Special thanks to Cameron Browne for creating Ludi and to Stephen Tavener for the game name and for coding it in 5 minutes on a Saturday morning. —description from the publisher
