Box league vs ladder vs round-robin

Round-robin: the season with a champion

Everyone plays everyone; most points wins the season. Best when the group is stable and wants a story with an ending — a champion, an archive, next year's revenge. Weakness: with big skill gaps, some matches are foregone conclusions.

Ladder: continuous and season-less

Players are ranked in a line; you challenge someone above you and swap places if you win. Great for clubs with rolling membership and no fixed season. Weakness: activity depends on people issuing challenges, and ladders quietly stall without an organizer nudging them.

Box league: even matches every cycle

Players are grouped into boxes of 4–6 by strength. Each month everyone plays their box; the top one or two move up a box, the bottom move down. This produces the most competitive individual matches of any format — you are always playing near-equals. Weakness: needs monthly administration, which is exactly the part worth automating.

Which one for your group?

A pragmatic default: run a round-robin season for the story, and if the group grows past twenty, split into strength-based divisions — you get the box league's even matches with the round-robin's championship arc.
