Survivor Pool Rules Explained: Entries, Buy-Backs, Ties and Tiebreakers

You joined a survivor pool, someone sent you a link, and the rules were three lines long in a group chat. This guide explains what those rules actually mean, which variants are common, and how each one changes the way you should play. Nothing here is invented — these are the formats real pools run.

The core rules every pool shares

• Pick exactly one NFL team each week to win their game.
• If your team wins, you advance to the next week.
• If your team loses, you are eliminated.
• You may not pick the same team more than once all season.
• Picks lock at the kickoff of the game you picked (some pools lock everything at the first kickoff of the week — check).

That no-reuse rule is the whole game. Any single week is easy; the season is hard because every strong team you spend is a team you cannot spend later.

Single-entry vs. multi-entry

Single entry

One life per person. This is the standard office pool. Because you cannot hedge across entries, survival is everything: you want the pick that keeps you alive with the best remaining board, and leverage only starts to matter once the field thins out.

Multi-entry

You buy several entries, each with its own independent used-team list. Large public pools often allow anywhere from two to dozens. Multi-entry changes the maths: your goal shifts from "keep this entry alive" to "maximise the chance at least one entry reaches the end." That means deliberately diversifying — putting entries on different teams in the same week — rather than duplicating your favourite pick across all of them.

Buy-backs, mulligans and rebuys

Buy-back

You are eliminated, you pay the entry fee again, and you re-enter — typically with a fresh used-team list and typically only through an early cutoff (weeks 2 to 4 is common). Some pools allow one buy-back per person, some unlimited until the cutoff.

Mulligan (strike)

Every entry gets one forgiven loss. Lose once and you continue; lose twice and you are out. Some pools call these "strikes" and allow two.

How they change strategy

A mulligan makes early aggression cheaper. If a loss in week 2 does not end your season, taking a contrarian pick while the field is still huge is far more defensible. In a strict one-and-done pool the reverse is true: early weeks are about not dying, and you save the clever picks for when the field is small enough that gaining ground matters.

Ties, pushes and games that do not happen

Your game ends in a tie

NFL regular-season games can end tied. Because survivor is a moneyline-style pick, the common rulings are: the tie counts as a loss (strict pools), the tie counts as a win/advance (player-friendly pools), or the tie is void and the entry advances with that team still marked as used — or, less often, made available again. There is no universal standard, so this is one of the first things worth reading in your pool's rules. Ties are rare but they have decided pools.

Push

"Push" is a point-spread term and mostly does not apply, because survivor picks are straight-up winners. It only comes up in spread-based variants, where a pick landing exactly on the number is treated as a tie under whatever the pool's tie rule says.

Postponed, cancelled or relocated games

If your game is moved to a later date, most pools grade the entry when the game is eventually played. If it is cancelled outright, entries on that game are usually voided and advanced. Relocation for weather does not change anything about grading, though it may change the odds a lot.

No pick submitted

The two common defaults are elimination, or an auto-pick — usually the biggest remaining favourite or the pool's alphabetically-first unused team. This detail catches out more players than any strategic mistake. Set a reminder.

Tiebreaker mechanics

Most pools do not end with one survivor. When multiple entries are still alive after the final week — or when everyone is knocked out in the same week — the pool needs a rule. The ones actually used:

1. Split the pot. The simplest and most common: all surviving entries share the prize equally.
2. Last entry standing wins outright, and if everyone dies in the same week the previous week's survivors split.
3. Continue into the playoffs, running the same no-reuse rules on the postseason slate until one entry remains.
4. Preseason tiebreaker question, submitted at entry — most often a total-points prediction for a designated game, closest without going over or plain closest.
5. Margin of victory, accumulated across the season or applied to the final week's picks: the surviving entry whose team won by most takes it.
6. Furthest advanced, then earliest submitted, used as a final deterministic fallback in some online pools.

Which one your pool uses should change your late-season play. A split-the-pot pool rewards pure survival. A winner-take-all pool with a margin tiebreaker rewards taking on a little more risk once the field is down to a handful.

Circa-style pools vs. the office pool

The best-known large public contest runs on noticeably tougher rules than a typical office pool: it is high buy-in, it has a very large field, it runs through week 18, and there is no mulligan and no buy-back. Some large contests also require picks for every week to be submitted under strict deadlines, and prize structures are top-heavy rather than an even split.

The practical consequence is that crowd-avoidance matters far more there than in a 20-person office pool. With thousands of entries, surviving is not enough — you have to survive in weeks where most of the field does not. In a small pool, the opposite: take the safe team, stay alive, and let other people's bad weeks do the work. A full side-by-side comparison is a separate guide.

The five questions to ask before your first pick

1. How many entries are allowed, and can I add more later?
2. Is there a mulligan or a buy-back, and until which week?
3. How is a tie game graded?
4. What happens if I forget to pick?
5. How is the prize split if several entries survive?
