Four ways to run it.
Many players, few rounds, nobody knocked out. Each round, players meet someone on their score they haven't played. Use it when the field is bigger than the rounds you have.
- Score group 2
- White P08 plays Black P02
- Score group 1½
- White P01 plays Black P04

- White P05 plays Black P11
- White P07 plays Black P13
- Score group ½
- White P12 plays Black P09
- White P10 plays Black P14
- White P16, floated up from 0 plays Black P15
plays up from a lower score group. White is named first.

5 · Checkers
Chess, and checkers done properly.
Checkers runs under FMJD rules in two variants: International on 10×10 and Brazilian on 8×8. Captures are compulsory and you must take the most pieces, kings fly, men capture backwards, and captured pieces come off only when the move ends. A variant is the rule set and a format is how you're paired, so a Brazilian Swiss is a normal event.
26x19x12x3x10x1: one move takes 5 pieces and ends on the far row, so the man is crowned.
