100 Days At Sea

100 Days at Sea is an open-world survival game on Roblox developed by Stranded Devs. You wake up in the middle of the ocean and must survive for 100 days by gathering resources, building a raft base, exploring islands, and fighting enemies. The game has earned over 98 million visits with a 97% rating and regularly peaks at 43,000+ concurrent players.

Classes are special loadouts you equip before each run. Each class has a star rating (1 to 6) indicating rarity and power. Higher-star classes offer stronger buffs but cost more Pearls to unlock. You unlock classes through a gacha-style roll system — spend Pearls to spin for a chance to unlock new classes. Classes grant passive bonuses like increased health, faster sprinting, or improved weapon damage.

Codes were introduced on June 27, 2026. To redeem, click on your currency counter in the bottom-left corner of the HUD to find the code entry field. Codes are case-sensitive and usually expire after a few days or weeks. Rewards include gems (premium currency), pearl sacks (for upgrades), cosmetic skins, and XP boosts.

The game features a comprehensive crafting system. You can build rafts ranging from basic wood to metal, container shelters, makeshift buildings, weapons like assault rifles, cooking items like fish sandwiches, and defensive structures like lightning rods. The Crafting 2.0 update (v4.0) overhauled the entire crafting economy with new island biomes.

Seeds determine your world generation — including beach loot, island layout, chest spawns, and animal distribution. A good seed means rich resources from the start, while a bad seed forces you to hunt for basic materials. While the game doesn't let you input custom seeds directly, community members have discovered start times that produce consistently desirable results.

Gather scrap items like stools and wood planks to fill the grinder to 100% and craft your first raft. Use your inventory (old sack) to hold everything you pick up so you don't waste trips. Prioritize food, water, and basic shelter before exploring islands. The first 10 minutes are critical — focus on getting your raft built and gathering nearby resources before sailing out.

You can team up with friends in multiplayer sessions. Set up co-op sessions to gather resources faster, revive each other in combat, and build larger bases together. Having a crew significantly increases your survival chances, especially during boss fights against krakens, ghost pirates, and giant angler fish.

The developers at Stranded Devs release updates regularly.
