The basic idea
In an NFL survivor pool, each entry picks one team each week. If that team wins, the entry survives to the next week. If that team loses, it uses a mulligan when one is available or is eliminated when none remain.
The twist is that most survivor pools do not allow repeat teams. Once you use a team, it is off your board for the rest of the season.
Common rules
Most pools use one pick per week, but some add double-pick weeks to increase difficulty. On Survive Sunday, commissioners choose whether an official NFL tie counts as a win or a loss.
Commissioners should make rules clear before Week 1: start week, pick deadline, mulligans allowed, tie rule, and whether playoffs are included.
Why organization matters
Survivor pools get messy when picks are tracked by text messages or spreadsheets. The commissioner needs clean locks, clear standings, and a record of which teams each player has already used.
A dedicated pool tool helps avoid arguments because picks, deadlines, and standings are visible in one place.
What happens from one week to the next
At the beginning of a week, every active entry sees the available NFL schedule and chooses an eligible team. A team is eligible only if its game has not locked and the entry has not already used that team during the applicable phase of the pool. Once the selected game reaches its deadline, the choice becomes final and is revealed according to the pool rules.
After games become final, winning picks advance and losing picks are charged against the entry. In a pool with no mulligans, the first loss eliminates the entry. In a pool with one or more mulligans, a loss consumes one before elimination occurs. A missed deadline is normally treated the same as a losing pick so every participant is judged by one predictable standard.
Deadlines and early games
The weekly deadline deserves special attention because NFL weeks do not always begin on Sunday afternoon. Thursday games, international games, Saturday games, and holiday schedules can all start earlier. A sound system never allows a participant to select or change a team after that team has kicked off, even when the pool uses a later fixed weekly deadline.
Some pools use rolling locks, meaning every matchup remains available until its own kickoff. Others use a fixed deadline, such as Sunday at 1:00 PM Eastern, with earlier games locking at kickoff. Neither format is automatically better. The important part is that the commissioner explains it before the season and the same clock applies to everyone.
Used teams change the strategy
A survivor pool is not simply a weekly exercise in selecting the largest favorite. The no-repeat rule creates a season-long resource problem. Using an elite team in an easy early matchup may feel safe, but that team will no longer be available when the rest of the schedule becomes difficult. Strong entries consider both the current chance of winning and the future usefulness of every team.
This is why two players can make different rational choices in the same week. One may prioritize survival with the safest available favorite. Another may accept slightly more risk to preserve that favorite for a scarce future week. Pool size, remaining opponents, mulligans, and teams already used all affect which choice makes sense.
Playoffs, ties, and unusual outcomes
Commissioners should decide whether the pool ends after the regular season or continues through the playoffs. Playoff rounds have fewer games, so available teams become scarce quickly. Some pools reset regular-season team usage when the playoffs begin, while others carry every used team forward. That decision should be written into the rules before anyone makes a pick.
Official NFL ties also need a declared treatment. A pool may count them as wins or losses, but deciding after a tie occurs is unfair. Postponed, suspended, or canceled games should follow a published administrative rule and should not be guessed at while the league is still determining the official result.
A simple example
Imagine an entry chooses Buffalo in Week 1 and Buffalo wins. That entry advances, but Buffalo is now unavailable for the rest of the regular season. In Week 2 the entry chooses Dallas and Dallas loses. If the pool allows one mulligan, the entry remains alive with no mulligans left. If the pool allows none, the entry is eliminated immediately.
The winner is usually the last entry still alive. If every remaining entry loses in the same completed week, the commissioner needs a wipeout rule. Survive Sunday keeps all of those entries alive for the following week while still recording the losing teams as used, preventing a full-pool loss from turning into an improvised decision.
