100 Days at Sea is an open-world Roblox survival game that challenges players to stay alive for 100 days after becoming stranded in the middle of the ocean. Inspired by popular survival experiences, the game combines resource gathering, crafting, exploration, and combat while uncovering the mysteries surrounding the Bermuda Triangle.
From building your first raft to unlocking powerful Classes and Companions, there’s a lot to learn during your first playthrough. This beginner guide covers the essential mechanics and early-game priorities to help you survive longer and progress more efficiently.
Start by Collecting Resources on the Beach
Every new adventure begins on a small beach where you’ll gather the materials needed to build your first raft. Before sailing into the open ocean, spend some time collecting every useful object scattered around the starting area.
Common materials include:
- Wooden Planks
- Metal Scrap
- Benches
- Broken Crates
Once you’ve collected enough materials, place them into the Grinder. Continue filling it until the progress reaches 100%, allowing you to construct your first raft and begin your journey across the sea.
Gathering everything available before leaving the starting island gives you a much stronger foundation for the days ahead.
Learn the Basic Controls
Understanding the core controls early will make every survival task much easier. Whether you’re collecting supplies or defending yourself against enemies, becoming familiar with these actions saves valuable time. Important controls include:
- Press E to pick up items.
- Store materials inside your Old Sack instead of carrying everything by hand.
- Hold Shift to sprint.
- Open every crate you discover for Coins and useful supplies.
- Defeat crabs on islands to obtain food when your health begins to drop.
Mastering these basic mechanics will make resource collection and exploration much more efficient.
Play With Friends Whenever Possible
Although 100 Days at Sea can be played solo, multiplayer offers several major advantages, especially during the early stages of the game.
Working together allows your group to:
- Gather resources much faster.
- Build and upgrade the raft more efficiently.
- Defeat enemies with less risk.
- Explore islands safely.
- Divide responsibilities between players.
If you have friends who play Roblox, starting a new survival run together can make the first several days considerably easier.
Build Essential Structures First
Once your raft is complete, your next objective should be improving your chances of survival. Some structures provide much greater value than others during the early game.
Cooking Pot
The Cooking Pot allows you to prepare food that restores health more effectively than raw ingredients. Having a reliable way to recover health becomes increasingly important as enemy encounters become more dangerous.
Crab Trap
The Crab Trap automatically generates food over time, reducing the need to hunt crabs on every island you visit. This passive food source helps maintain a stable supply throughout your survival run.
Map Radar
Exploration becomes much easier after building the Map Radar. It helps you locate new islands more efficiently, making it easier to gather rare resources and continue progressing through the game.
Prepare Carefully Before Night Falls
Nighttime is one of the most dangerous parts of every survival cycle. Enemy activity increases, visibility becomes limited, and traveling across the ocean is much riskier.
To improve your chances of surviving each night:
- Stay close to your raft whenever possible.
- Avoid unnecessary exploration after dark.
- Keep your health near maximum.
- Eat food before your health becomes dangerously low.
- Make sure your equipment is ready before sunset.
Good preparation during the daytime often determines whether you’ll survive until morning.
Complete Quests for Valuable Rewards
Quests serve as one of the best progression systems in 100 Days at Sea. They provide clear objectives while rewarding players with valuable resources that accelerate account growth.
Benefits of completing quests include:
- Pearls
- Progression rewards
- Helpful resources
- Long-term account advancement
Checking your quest list regularly ensures you don’t miss opportunities to earn premium currency and useful materials.
How to Get Pearls
Pearls are the premium currency used to unlock several important progression systems throughout the game.
You can earn Pearls by:
- Redeeming active codes
- Completing quests
- Unlocking achievements and badges
- Joining the official Roblox developer group
- Purchasing Pearl bundles
Since Pearls are relatively difficult to obtain, it’s usually best to save them until you’re certain what you want to unlock.
Redeem Active Codes
Whenever the developers release redeem codes, they provide one of the fastest ways to earn free rewards.
To redeem a code:
- Open the Codes menu.
- Enter an active code.
- Press Redeem.
- Claim your rewards immediately.
Be sure to redeem new codes quickly, as many promotional codes are only available for a limited time.
Earn Additional Rewards Through Achievements
Achievements and badges offer another reliable source of progression rewards. As you survive longer and complete different objectives, you’ll unlock additional bonuses that help strengthen your account.
Common achievement goals include:
- Surviving a certain number of days.
- Completing gameplay challenges.
- Exploring new locations.
- Reaching important milestones.
Continuing to play naturally will gradually unlock these rewards over time.
Unlock Companions for Passive Bonuses
Companions are pets that provide passive abilities while you play. They can greatly reduce the amount of manual work required to survive by assisting with food collection and other helpful tasks.
Companion Chests currently include:
- Fisherman’s Chest — 40 Pearls
- Warrior Chest — 80 Pearls
- Ice Chest — 120 Pearls
- Pirate Chest — 120 Pearls
- Magma Chest — 120 Pearls
For new players, the Fisherman’s Chest offers the best value because it’s the least expensive option.
If you’re looking for the strongest long-term Companions, two popular choices stand out:
- Seagull (Pirate Chest)
- Crow (Magma Chest)
Both automatically gather nearby food approximately every 120 seconds, helping you maintain a steady food supply throughout your survival journey.
Choose the Right Class
Classes provide permanent starting bonuses that activate whenever you begin a new survival run. Selecting the right Class can dramatically improve your overall performance from the very first day.
Depending on the Class you unlock, bonuses may include:
- Higher maximum health
- Increased damage
- Faster movement speed
- Better overall survivability
Because these bonuses apply at the start of every game, Classes are considered one of the best long-term Pearl investments for players who plan to play regularly.
100 Days at Sea offers a rewarding blend of open-world exploration, survival mechanics, crafting, and progression systems. Success depends on balancing resource management, raft upgrades, exploration, and combat while preparing for increasingly difficult challenges as each day passes.
New players should focus on building essential structures, completing quests, collecting Pearls, unlocking useful Companions, and investing in a Class that matches their preferred playstyle. By establishing these fundamentals early, you’ll be well-equipped to survive the full 100-day adventure and uncover the secrets hidden across the mysterious ocean.
