Alternate rules and scoring
The wraparound rule ("Advanced Mǽrstánas")
When considering hinges for edge positions, instead of counting the edge as a hinge, look at the position on the opposite side of the board.
For example, position A2 would only count a hinge if a friendly stone was placed at G2. Likewise B3 would need to look at B7.
Stones places in corners would need to consider both opposing corners.
When the "wraparound" rule is in effect, edges are not automatically scored as hinges. Only true stone-to-stone hinges, including wraparound positions, are scored.
Note: This rule may create positions that normally look unplayable. Care must be exercised when looking at edge plays.
Simple scoring
When playing with the default / traditional ruleset, disregard scoring all edge hinges. This results in a lower scoring game but may make it easier for new or younger players to grasp scoring more quickly.
