Every format above, Loser Pool, Double Pick Weeks, Against the Spread, playoff weeks, works as a standalone pool. But they're also settings, not separate products, which means a commissioner can turn them all on at once. As of today, we haven't found another platform that lets you do that. Most sites give you one flavor of survivor pool. Sunday Survivor lets you stack them.
We call it the extreme survivor pool. Some commissioners call it a survivor pool on steroids. Whatever you call it, it's the hardest version of this game you can run.
What's Actually Stacked
- Double Pick Weeks: in designated weeks, every entry needs two winning picks, not one. Both have to hold up or the entry's out. You can go further and require the first of those picks to come from a specific set of games you choose.
- Against the Spread: "winning" isn't enough. Each pick has to cover the point spread, locked in every Wednesday at 12:00 PM ET.
- Loser Pool: the whole objective flips. Instead of picking a team to cover, you're picking a team you think won't cover.
- Playoffs: Week 18 stops being the finish line. If more than one entry is still alive, the pool runs on through the Wild Card round to the Super Bowl.
- No Repeat Opponents: you can't pick against the same team two weeks running, so one bad team can't be farmed for easy wins week after week.
Combine them and here's what a normal week actually asks of you: pick two teams you think will fail to cover the spread, not two teams you think will simply lose, from a board that shrinks every week as your used teams and their recent opponents come off it. If either pick surprises you and covers, your season is over. There is no bracket to fall into.
Why Commissioners Run It
Any one of these settings adds real difficulty on its own. Stacked together, the pool stops being about who can spot an obvious mismatch and turns into something closer to real handicapping, every single week, twice a week when the schedule calls for it. For a group that's outgrown the standard format and wants bragging rights that actually mean something, this is about as hard as a survivor pool gets.
One setting is deliberately missing, and it's the one people expect to see here. Second Chance gives an eliminated entry a runner-up bracket to keep playing in, which is a fine thing to run and the opposite of what this format is for: it makes a bad week survivable. The extreme pool leaves it off. One wrong pick is the whole season.
Closing the Easy-Win Loophole
Every survivor pool has one soft spot: the league's worst team. You don't have to pick them, you just pick whoever is playing them. A different team every week, so the no-repeat-teams rule never bites, and a chunk of the season becomes close to automatic.
No repeat opponents closes it. Beat the Jets in Week 3 and you can't pick whoever plays the Jets in Week 4. You can stretch it beyond one week if you want the pool forced even wider. In a loser pool the same rule catches the mirror-image exploit, where the free win is picking whoever faces the best team in the league.
Stacked with against the spread, this is what makes the format genuinely hard rather than just fiddly: your safest matchups get used up, and the ones left have to cover a number.
No Off Ramp: The Playoffs
A normal survivor pool ends at Week 18, and if several entries are still standing they finish as co-champions. That's the soft landing this format takes away. With playoff weeks on, a pool that hasn't produced an outright winner by Week 18 keeps going: Wild Card, Divisional, Conference Championships, Super Bowl. Somebody has to actually win it.
Used teams reset when the playoffs start, which sounds like mercy and isn't. Thirteen games across four rounds means the board collapses under you: six games, then four, then two, then one. By the Super Bowl there are exactly two teams left in the league, and if you have already spent both of them there is no legal pick to make. Entries have gone out at that point having never lost a game all season.
It only comes into play when the pool needs it. If Week 18 produces a single survivor, they have won and the playoffs never happen. This is the setting that stops a season of this difficulty ending in a four-way tie.
Double pick weeks do not carry into it. They are a regular-season setting, capped at Week 18, and the playoff rounds are single-pick: by the Super Bowl there is one game, so there is no second game to take a second pick from. Everything else you have stacked still applies.
The Hardest Setting of All: Required Games
If all of that still isn't enough, there's one more screw to turn. On any double pick week, you can require the first pick to come from a slate of games you pick yourself. The obvious use is the holidays: force one pick out of the Thanksgiving or Christmas games.
This is harder than it sounds, and the reason is teams are single use. The Thanksgiving slate is five games, so ten teams. Christmas is four games, eight teams. Worse, those two sets overlap heavily, so spending a shared team in November deletes it from your December options. Every entry now has to reserve eligible teams from the start of the season and protect them for months. Burn them early on easy wins and you arrive at Thanksgiving with nothing legal to play, which means no pick, which means you're out.
Stack that on top of everything else and one November week asks you to find a team from a five game slate that you believe will fail to cover the spread, plus a second team from anywhere in the week that will do the same, and get both right. That's the ceiling of this format.
Because it's a planning rule rather than a gotcha, the required games are published to every member before the season starts and are visible all season, along with which eligible teams each entry still has left. Nobody gets ambushed in November. They just have to have planned for it.
How to Enable It on Sunday Survivor
Each of the settings, double pick weeks, ATS, loser pool, playoff weeks, and no repeat opponents, is its own toggle in your pool settings. Turn them on before your first pick deadline and the platform grades every pick against every rule automatically: which teams to cover, which weeks need two picks, how a loser-pool result inverts, and whether Week 18 is the end of your season or the start of a playoff run. No manual tracking, no spreadsheet on the side. Required games are set per double pick week, right under the week picker, by ticking the games that count. Like the other settings, they lock once your first game kicks off, so the rule your members planned around can't move underneath them.

Frequently Asked Questions
What is an extreme survivor pool?
A survivor pool running Loser Pool, Double Pick Weeks, Against the Spread, no repeat opponents and playoff weeks all at the same time. Each setting works on its own. Combined, they make the hardest version of the game: one wrong pick ends your season, and Week 18 isn't necessarily the end of it.
Does any other platform let you combine these settings?
Not that we've found. As of today, Sunday Survivor is the only survivor pool platform we know of where Loser Pool, Double Pick Weeks, ATS and playoff weeks can all run in the same pool at once.
Do I have to turn them all on?
No. Each one is an independent toggle in your pool settings. Run any single format on its own, mix two or three, or stack them all for the extreme version.
How does grading work with everything on?
The platform applies every rule automatically: which weeks need two picks, which teams need to cover the spread, how the loser-pool flip applies to that result, which teams a repeat-opponent rule or a required slate has taken off the board, and whether the season ends at Week 18 or runs on into the playoffs.
Want the mechanics of each format on its own? See our guides on ATS survivor pools, loser pools, double pick weeks, and playoff weeks. Want the softer version instead? A second chance bracket keeps eliminated entries playing, which is the one setting this format leaves off.
