Leagueborn is a fantasy football card game built from your real Sleeper roster. Every player becomes a card rated from their weekly fantasy points in your league, and you duel leaguemates, with a Sunday round scored by real games.

Is the fantasy football card game free?

Yes. Roster Deck is free. Open your league with a public Sleeper username, no password, and tap Roster Deck.

How are Roster Deck cards rated?

From each player’s real weekly fantasy points in your league. Ceiling is the best week, Form is the last three weeks, and Floor is the low end of a normal week. The overall rating runs from 40 to 99 and sets the rarity.

Who do I play against?

Your leaguemates’ real rosters. Their three cards lock before you pick yours, so nobody has to be online at the same time.

Do the cards change during the season?

Yes. Cards re-print every time a week goes final, so a breakout Sunday upgrades the card and a quiet one cools it off.

Do I give Leagueborn my Sleeper password?

No. Leagueborn uses a public Sleeper username for lookup and never asks for your Sleeper password.

Which fantasy provider is supported?

Sleeper is the current provider. ESPN, Yahoo, and NFL Fantasy are not supported.

Is Roster Deck daily fantasy or betting?

No. There is no entry fee, no prize, and no money involved. Roster Deck is a free game played with the points your league already scored.

DealYour roster becomes the deckEvery player on your Sleeper roster becomes a card rated from their real weekly points in your league. Your hand is this week’s starters, topped up from the bench.
DuelThree rounds now, one on SundayCall out any leaguemate. Their cards lock face down, then you set one card each on Ceiling, Form, and Floor, plus a fourth that scores on its real points this Sunday. The Sunday round counts double.
Re-printThe deck changes every weekCards re-print each time a week goes final. A breakout Sunday upgrades the card, a quiet one cools it off, and a live game never moves a card mid-slate.
