Carlo (Carlo rule-also known as backgammon, popular in Vietnam): The winner must have a long line or five in a line, and the ends must not be blocked: XOOOOOX and OXXXXXO do not count as winning lines. Gobang standard: first in a horizontal, vertical or diagonal line (gobang or gobang), the winner is the winner. Long line-six or more pieces of the same color are connected in a line without scoring.
