Each border has a point value from 0-4; totalling these gives a score for each card between 0-16.
Border score turns visible edge markings into a clean 0-16 number.
The values are distributed inverse-linearly through the deck; there are 16 cards with value 1, 15 with 2, 14 with 3, up to 1 card with value 16 (and a leftover of 14 card with value 0).
A player can manually sum the border pips, or use the border pie chart beneath the compass for quick reference.
Use the total as a point value, tiebreaker, cost, or difficulty.
Build around thresholds, exact totals, increasing paths, or score-matching placement. The printed total avoids repeatedly summing the edge pips.
Border score relates the border sides and are distributed through the deck in a pattern relating to suit and rank.
