What you get
Everything a league needs.
Nothing it doesn't.
LeagueKing is built for real, repeating seasons — not one-off events. Auto-generated matchups, RSVP tracking, division promotion, and tournament brackets, all in one place.
Weekly Matchups
Auto-generated pairings, locked when you say so.
Hit Regenerate and only the random rows redraw — manual pairings stay locked. Need to swap a single team? Pick a specific opponent or roll the dice; either way the displaced teams end up playing each other automatically.
- RSVP-driven scheduling
- Manual pairings preserved on regenerate
- Specific-team swap with auto-rebalance
- Per-week locking & history
Divisions & Standings
Promotion. Relegation. Real stakes.
Teams move up or down every four weeks based on RPI rankings. Standings update automatically as scores come in, so the table always reflects what just happened on the field — no spreadsheet babysitting.
- RPI-based rankings
- Configurable division sizes
- Auto promotion / relegation cycles
- Live standings & game logs
Smart Notifications
Right message, right phone, right time.
Optional SMS reminders for RSVPs, score deadlines, payment receipts, and matchup announcements — sent only to players who opt in on their profile, on a configurable schedule. Reply STOP anytime to opt out.
- Passwordless phone & email login

Frequently asked
Questions before you commit.
What sports does LeagueKing support?
Any sport with weekly head-to-head matchups and a single-elimination tournament at the end. Currently configured for soccer-style scoring out of the box; commissioners can adjust scoring rules per organization.
Do players need to install an app?
No. The whole site is mobile-first and works in the browser. Players sign in by phone (a one-time SMS code) — no passwords, no app store.
How do payments work?
LeagueKing uses Stripe. Captains pay a per-team registration fee at sign-up time. Receipts are emailed automatically and refunds are issued through the Stripe dashboard.
Who runs my league?
You do. Every organization on LeagueKing is owned and administered by its own commissioners. We provide the platform; you run the games.
Is there a free trial?
The leagues currently using LeagueKing pay a small per-team fee through Stripe. Reach out via the league you want to join and the commissioner can walk you through pricing for your organization.
