100 Days At Sea Wiki — Guides That Don't Make Things Up

How a run of 100 Days at Sea actually works

You are dropped into open ocean on a raft barely worth the name, and the clock starts. The developer's own listing describes it as an open-world survival game "where exploration and base building is the key to survival", and its four-line how-to-play is the honest short version: grab resources or hook them with your Harpoon, build your raft base with structures and defenses, explore the sea and visit mysterious islands, find weapons and take on fearsome foes. Everything below that is the texture.

A run is one to five players— the game's official badge list carries a separate badge for every party size, from "All Alone" (100 days completely solo) up to "And they were crewmates..." (a full group of five). The servers themselves hold up to 27. Days pass on a cycle, and the two halves of it play completely differently:

• Daytime is economy.You harpoon floating wood, planks, furniture and crates out of the water, run them through structures like the Sawmill, and sail out to islands for loot the sea won't give you.
• Night is threat. The Angler Fishhunts anyone off their raft after dark or without a lit Bonfire, and it does not break chase. Ghost raids come for your base — the official badge "They'll be back!" is simply for surviving one, and 40.7 million players have earned it, so they arrive early and often.
• The Bonfire is the spine of both. Badges confirm levels 1 through 7 plus a max level, and each level gates more of the build menu — the Sawmill at level 3, the Magnet at level 4. Feeding it is simultaneously your progression and your night defence.

Dying is not instant. You get knocked down with a bleed-out timer, and a teammate can pick you up before it expires; if it runs out you are eliminated for the rest of that run, which is why solo play leans so hard on prevention. The full rules are on the revive page.

Reach the end and the game tells you what the story was about: the Day 100 badge is called "Rescued!". And the run doesn't have to stop there — there are official badges for Day 250 ("Stranded") and Day 500 ("Gone Missing"), earned by 80,152 and 19,489 players respectively.

How far do players actually get?

Nobody publishes a difficulty rating for this game, but the developer accidentally publishes something better. Every day milestone has an official Roblox badge attached, and Roblox reports how many players have earned each one. Read top to bottom, that is an attrition curve — and it is the closest thing to an honest answer about how hard 100 Days at Sea is. Figures below were pulled from the official badge endpoint on July 26, 2026.

Three things fall out of that table. The first three weeks are the filter — of the 46.8 million players who have survived Day 1, only about one in six ever earned the Day 20 badge. Finishing is rare but not exotic: 893,854 players hold "Rescued!", roughly one in fifty of the Day 1 crowd. And the back half is far kinder than the front half — about 42% of players who reached Day 50 went on to finish, and 92% of those who reached Day 90 did. Once your raft, your Bonfire level and your defences are established, the game stops trying to kill you nearly as hard as it does in week one.

Where these percentages come from. All of them are Roblox's own public badge counts for this game, read on 2026-09-01, divided by the 90,280,294players who hold "Out At Sea" — the badge you get for launching the game at all. Roblox awards badges once per player for life, not once per run, so these say how many people have ever reached a milestone, not what fraction of runs succeed.

Your first ten minutes, if you just want to start

Given that Day 20 is where most players stop, the early game is worth getting right. This is the short version of our beginner tips and day guide, in the order you should do it:

1. Harpoon everything that floats. Planks, furniture, crates, birds. Your entire early economy arrives by hook — 51.4 million players have the "Hooked!" badge for their first grab, and it is the first thing the game teaches for a reason.
2. Build a Sawmill (10 Wood + 2 Metal). It unlocks once your Bonfire reaches level 3 and converts scrap wood into planks. Experienced players run two, because plank supply is the first real bottleneck.
3. Set a Crab Trap. Passive food means hunger stops being a decision you make every day.
4. Feed the Bonfire, always. It is your progression gate and the only thing keeping the Angler Fish off you at night. Most early run-enders trace back to a fire nobody topped up.
5. Do not swim at night. Off the raft after dark is the Angler Fish trigger. If it is already chasing, a Flare Gun redirects it.
6. Push to Bonfire level 4 and build the Magnet (30 Metal + 10 Wood). From there metal is effectively unlimited and the run changes character — the 17.8 million Bonfire 4 badges against 7.3 million at level 5 mark roughly where the difficulty curve bites.

FAQ

• What is 100 Days At Sea?

  A Roblox survival game by Stranded Devs, officially inspired by 99 Nights in the Forest. You're stranded in the middle of the ocean: harpoon floating resources, build up a raft base, sail to islands, survive escalating nights, and make it to Day 100 while uncovering the mystery of the Bermuda Triangle.

• How popular is 100 Days At Sea right now?

  Very. Re-checked on July 26, 2026 against the official Roblox listing: 207 million total visits, 5.39 million favourites and a 97.3% rating (448,306 up-votes against 12,466 down). Its all-time concurrent-player peak of 81,186 was set the week before that check.

• How many players finish a 100 Days At Sea run?

  Far fewer than start one. The game's official badge list shows 46.8 million players have earned the Day 1 badge and 893,854 have earned 'Rescued!' for reaching Day 100 — roughly one in fifty. Note these are lifetime per-player badges, not per-run statistics.

• Can you play 100 Days At Sea solo or with friends?

  Both. The official badge list has a dedicated badge for every party size from solo ('All Alone') through duo, trio and four up to a full group of five ('And they were crewmates...'), so a run is 1–5 players. The servers themselves hold up to 27.

• Is 100 Days At Sea related to 99 Nights in the Forest?

  Yes — the developers say so themselves. The official game description opens with 'Inspired by 99 Nights in The Forest.' It's the same survive-the-nights formula moved onto a raft at sea.

• Does 100 Days At Sea have codes?

  Yes. A codes system was added around June 27, 2026, redeemed via the CODES button at the top-left of the screen. Codes expire in roughly 2–3 week windows — see our codes page for the current, dated list.
