Features
The same cards you will use after sign-in: organisations, lineups, matches, and permission bits — not screenshots, and not a second UI.
What you get on Pickup
Core play is free. The scenes below are illustrative North Table results — the cards are the ones in the app; the numbers are a story.
Organisations as home base
Create an organisation, bring members in, and keep one clear activity pool for invites, matches, and rankings.
Invites and permission bits
Owners, admins, and members share a ladder without sharing the same keys. Fine-grained bits; ownership stays non-delegable.
Record matches of any shape
Log 1v1, 2v2, uneven lineups, and N-way games inside an organisation — scores become win, lose, or draw.
Rate lineups, not people
TrueSkill lives on each team roster fingerprint. Memberships carry permissions; skill stays on the lineup that played.
Standings that stay honest
Ratings are projected from an append-only match history, so every effective result is reflected in the board.
Corrections without rewriting history
Mistakes become tombstones and corrections, not silent edits. The projector replays the effective record.
In the app
Organisations as home base
One organisation is one activity pool in v1. Invites, matches, and rankings all live here — this is the same org card you see on the app home.
North Table
Membership
Invites and permission bits
Permission bits sit on membership, never on skill. Owner is non-delegable. The badges on these member cards are the same ones you will see in the organisation.

Match history
Record matches of any shape
Any number of competing fingerprints can sit in one result. Scores collapse to win, lose, or draw — no margin math, no placement column. These are the match cards from history.
11 – 7
- Alpha 11
- Solo 7
Alpha took the table. Solo’s fingerprint moves; the pairs wait for their next game.
12 – 9 – 9
- Solo 12
- Beta pair 9
- Night shift 9
Three fingerprints, one ordinal — no placement column.
Team ratings
Rate lineups, not people
A duo rating is the duo. A solo rating is a size-1 team. There is no overall member μ/σ — these team cards are the only rating locus in the product.

The board
Standings that stay honest
Standings are teams sorted by μ. After a match lands, the projector replays effective history and the board updates — the same cards, no hand-edited ranks.

Corrections without rewriting history
You never reverse TrueSkill in place. A bad result is tombstoned; a correction is a new fact. The projector skips the tombstone on the next full replay.
11 – 5
- Solo 11
- Alpha 5
Wrong score entered. Tombstoned — the projector skips it on replay.
