=== USPA ===
The older notation system was used by the USPA for its newsletters and documentation of tournament games. The notation system was based on an xy 2 dimensional grid used in mathematics. The center of the board was notated as "0". Points on the board were measured based on their distance and direction from the center. The four cardinal directions were notated as L, R, U, D for Left, Right, Up, Down, while the number of spaces in any of the directions were notated by a number signifying the empty intersections away from "0." A stone two intersections right and seven intersections up would be recorded as R2U7. If a stone was on the same vertical or horizontal axis as the center point, then the "0" would be left off of the notation. A stone two intersections up from center and zero intersections left or right would be notated simply as U2. Capture moves were notated by placing an asterisk following the notation for the stone's location. For organization, moves were recorded as sets with white's ply on the left and black's ply on the right, and numbered in ascending order according to when they happened in the game.<ref>{{Cite journal|last=Braunlich|first=Tom|date=Summer 1983|title=Pente Notation|url=http://www.playpente.com/newsletters/summer_83.pdf|journal=Pente Newsletter|volume= |pages=24|archive-url=https://web.archive.org/web/20040613100617/http://www.playpente.com/newsletters/summer_83.pdf|archive-date=2004-06-13|via=}}</ref>
