Why This 100 Days at Sea Guide Matters
You spawn on a tiny raft with nothing but a harpoon, a fishing rod, and the open ocean stretching in every direction. Every night brings tougher enemies, and by day 20 you’ll face raids that can wipe out an unready base. Getting your early decisions right is the difference between a quick death and reaching the final day. This 100 Days at sea guide breaks down everything you need to know — from resource gathering to the best classes — so you can survive the full 100 days.
How to Farm Resources Efficiently
Wood and Metal are the backbone of every craft in the game. Everything else becomes manageable once you have a steady supply of both.
Wood: Your First Priority
Start by using your harpoon to grab floating planks, furniture, and broken crates from the water. Deposit them into the crafting machine or directly into the Bonfire to level it up. According to the Pro Game Guides article, your immediate goal is reaching Bonfire Level 3, which unlocks the Sawmill. The Sawmill is an infinite wood generator — place it on your raft and it produces 3 planks per use for a small wait. Build at least two Sawmills as soon as you can; solo players often rely on them to keep up with wood demand.
Metal: Harder to Find, Worth the Hunt
Metal is rarer early on. You can fish it out of the sea with the harpoon, but it’s more reliable to loot it from islands and store it in your sack. Once you hit Bonfire Level 4, craft the Magnet. Like the Sawmill, it sits on your raft and passively pulls in metal. It’s slower, but it never runs out. Player experience from the YouTube video shows that metal shortages can be a constant pain point — the Magnet solves that.
Green Gum and Other Oddities
You might notice a sticky green substance when you craft. It comes from feeding Ghost Pirate corpses into the crafting machine. Don’t leave their bodies on the deck — always collect them.
Food Sources: Keeping Your Crew Fed
Starvation kills your health regen and eventually your character. Set up a food supply before day five.
| Method | How It Works | Best For |
|---|---|---|
| Fishing | Use the starting rod – throw bait, click when you get a bite. Simple but time‑consuming. | First few days |
| Harpoon Birds | Shoot birds flying overhead – they drop Cooked Bird, which fills a big chunk of your hunger bar. | Mid‑game boost |
| Crab Trap | Building you craft – passively collects fish and food every few seconds. | Passive supply |
| Pizza Oven | Another auto‑food building – cooks seafood pizza for the crew. | Late‑game convenience |
The Crab Trap is widely considered the best early investment in food. Once you have a steady wood source, build one or two. Important: always keep spare food in your inventory. The Fisherman NPC (found on the nearest island) trades food for high‑tier loot like weapons and buildings.
Best Build Order for the First 20 Nights
What you build and when matters more than anything else in this 100 Days at Sea guide. Here’s the recommended order, based on the Pro Game Guides article and community tested strategies:
| Order | Building | Why It’s Essential |
|---|---|---|
| 1 | Sawmill (at least 2) | Infinite wood – lets you expand and craft freely. |
| 2 | Crab Trap (1‑2) | Passive food removes a major stressor. |
| 3 | Map Radar | Shows all islands on the map – stops you sailing blind. |
| 4 | Auto Turret | Buys from Travelling Merchant for 150 Doubloons – handles night raids solo. |
| 5 | Magnet | Solves metal shortages (unlocked at Bonfire level 4). |
| 6 | Radio | Reveals survivor locations – rescued survivors boost day multiplier. |
Why this order works: You solve wood first, then food, then exploration and defense. The Auto Turret is a game‑changer for solo players — it deals with Ghost Pirates while you focus on looting. Players report that ignoring defense until night 10 can end a run fast.
Islands to Explore (and Which to Avoid)
Not all islands are created equal. Some are safe early visits; others require high‑tier gear.
Must-Visit Early Islands
- Fisherman Island: The closest island. You’ll almost always find a chest with a Dinghy — a faster boat that speeds up exploration. Trade food with the NPC here for powerful items.
- Mini Islands: Small, scattered, and almost unguarded. Each holds 1‑2 chests and loose loot. Grab everything while you sail by.
- Alien Island: Appears after you repel the Alien Invasion around night 6‑7. Use the Transponder item to find it. High‑tier loot inside.
Islands to Save for Later
- Survivor Islands: Guarded by waves of Ghost Pirates. Bring good weapons and armor before attempting.
- Tower Island and Fortress Islands: Require keys and are packed with strong enemies. If you’re solo, skip these until you have a strong base and high‑tier equipment.
Player experience from the YouTube video shows that trying to rush a Fortress island with only a hatchet leads to a quick death. Stick to Fisherman and Mini islands in the first 15 days.
Mobs and How to Survive Each Type
| Mob | When It Appears | How to Counter |
|---|---|---|
| Angler Fish | Night, if you leave the raft or bonfire dies | Keep bonfire lit; use a Flare Gun to distract it. |
| Sharks | Near islands, in the water | Get out of the water fast – don’t fight. |
| Tribal Mobs | On islands and during raid nights | Use melee or ranged weapons. |
| Ghost Pirates (Melee/Gunner) | Night raids | Melee works; collect bodies for green gum. |
| Aliens | Event around night 6‑7 | Easy with a sword or any melee. |
The Angler Fish is the deadliest threat in the game. It chases you relentlessly if your bonfire goes out. One community trick: always keep spare fuel in your inventory to relight the fire immediately.
Best Classes and How to Earn Pearls
Classes are bought in the lobby with Pearls (premium currency). They shape your playstyle heavily.
| Class | Stars | Cost (Pearls) | Key Benefit |
|---|---|---|---|
| Alien Overlord | 6★ | 750 | Starts with a Raygun and UFO ship; 50% cooldown at max level. |
| Raider | 6★ | 750 | Dual pistols; ammo from kills; magazine grows every 5 kills. |
| Ancient Squid | 6★ | 750 | Squid Laser Gun; +15% speed and +20% damage at max level. |
| Treasure Hunter | 5★ | 500 | Extra sack slots, 150 Doubloons, +25% doubloon bonus – huge early economy. |
How to Get Pearls for Free
- Achievements & Badges: Complete milestones to earn Pearls.
- Daily Quests: Small but steady income.
- Active Codes: Redeem codes from the official social channels.
- Crafting: Only at max Bonfire level – very slow but possible.
The Treasure Hunter is often recommended for beginners because the extra doubloons let you buy a good weapon and the Auto Turret early.

A: Redeeming active codes is the fastest method. Check the official Roblox game page or community Discord for the latest codes. Completing daily quests and achievements also adds up over time.
Q: Can I play 100 Days at Sea with friends?
A: Yes, the game supports co‑op. Playing with friends makes raids easier and resource gathering faster. The build order remains the same, but you can afford more Sawmills and Crab Traps early.
