About OnSzn Fantasy Sports

OnSzn is fantasy football for leagues that want to play their own way. Most fantasy apps give you one format and a handful of switches. OnSzn gives you the whole thing: redraft, keeper, dynasty, salary-cap auction with real contracts, best ball, and a zombie format where an undead team drafts from the undrafted pool and steals a player from whoever it beats. RUN THE LEAGUE YOU ACTUALLY WANT • Any league size from 2 to 32 teams — odd numbers included, with byes that play the league median • Scoring you control down to the individual stat, including team defense • Positional limits, roster slots, playoff structure and tiebreakers DRAFT IN REAL TIME • Live draft room with a pick clock, autopick, and queue • Pin the panels you care about side by side on desktop • Chat with the league without leaving the draft WATCH IT HAPPEN • Live scoring that updates while games are in progress • Matchup cards, box scores and a command center for the day's games • Power rankings with a written breakdown of where your team actually stands KEEP THE LEAGUE TALKING • League chat, group messages and direct messages • Push notifications for trades, waivers, draft picks and game results • Trade proposals stay private between the two teams until they're accepted SETTLE IT AT THE END • An optional league ledger for the friendly challenges and dues your league already tracks in a group chat, in units your league names itself • Challenges are proposed and accepted like trades, and the common ones — a matchup, two players head to head, a standings finish — settle themselves • Commissioner tools for dues, payouts and the end-of-season tie-out Free to use. No ads, no trackers, no analytics, and nothing sold to anyone. OnSzn processes no payments. The optional league ledger records friendly challenges and dues between league members in units your league defines — there is nothing to buy, no odds, no wagering, and no money moves through the app.
