How to Unlock Multiplayer in Starsand Island: Smooth Sailing Guide

A Steam Community walkthrough says to open the phone's Island Life app and keep completing its milestones until Smooth Sailing. The listed route is Returning Resident, Apprentice Talent, Decorate Your Home, First Pot of Gold, Junior Talent, Island Pro, then Smooth Sailing. The guide says Smooth Sailing requires meeting all mentors and helping Marston build the Maritime Bureau, after which multiplayer appears. This is a community report, not an official universal unlock rule. The official Version 1.08.3916 notes also say an entrance that failed to unlock after Smooth Sailing was fixed, so update and restart before treating a locked entrance as proof that the taskline is wrong.

Prerequisites

  • Use the current Version 1.0 build or later.
  • Open the phone and find the Island Life app; some pages may translate the name as Islander Life.
  • Keep the platform, build, save, and last completed milestone when comparing reports.

What to do now

Text walkthrough. Matching, reusable gameplay screenshots are not available for these steps. No image here is presented as our own playtest.

Steam / PC; community milestone route from August 18, 2026. Exact build unknown; not playtested by us.

  1. Open Island Life and find your current milestone

    Open the phone's Island Life (Islander Life) app. Follow its incomplete milestone rather than guessing an hours-played requirement.

    Look for this
    The current milestone name and its unfinished objectives.
    Before moving on
    You can identify the next uncompleted Island Life objective.
    If it does not match
    If the app or milestone differs, compare your build and last completed task; this community route is not a universal unlock guarantee.

    Screenshot unavailable: Phone screen with the Island Life app and active milestone.

  2. Work through the earlier milestones

    The community checklist lists Long Time No See!, Apprentice in any profession, six placed furniture items, 2,000 accumulated Coins and meeting ten Islanders. Then check Junior in any profession, five Bulletin Board requests and one land expansion via Phone > Buy Land.

    Look for this
    The app's own counters and completion marks for each requirement.
    Before moving on
    The app advances past the earlier milestones; a purchased item alone is not a completed milestone.
    If it does not match
    If a counter is incomplete, finish that named objective before skipping ahead to Smooth Sailing.

    Screenshot unavailable: Milestone counters before and after completing the listed objectives.

  3. Finish Smooth Sailing, then test the multiplayer entry

    At Smooth Sailing, check the reported Meet All Mentors and Marston's Maritime Bureau objectives. After the milestone completes, check whether the multiplayer entry becomes available.

    Look for this
    Smooth Sailing completion and an accessible multiplayer entry.
    Before moving on
    The entry is usable. A real host-and-guest join is the separate test that multiplayer works.
    If it does not match
    If it stays locked, use the still-locked guide below with your build and milestone state; do not erase the save.

Check that it worked

  • The Island Life app records the required milestone as complete.
  • The multiplayer entry opens; test a compatible friend's actual join before calling the whole session fixed.

Troubleshooting

Smooth Sailing complete, entry still locked
Keep the existing save. Compare the installed build and exact completed objectives using the still-locked guide. Open the relevant guide.
Entry opens, but a guest cannot join
Treat this as a connection/access problem, not an incomplete Island Life milestone. Open the relevant guide.
  • If multiplayer is still unavailable after Smooth Sailing, update to the current build, restart the game, and recheck the phone app and host settings.
  • Confirm the save actually marks the mentors, Maritime Bureau, and final milestone complete before reporting a soft lock.
  • Check the multiplayer-still-locked-smooth-sailing page for the patch-aware recovery flow.
  • Do not delete the save or claim that a fixed number of hours is required without a reproducible test.

Exceptions and branches

  • The Steam guide calls the final gate Smooth Sailing; other community reports describe it as the Island Life milestone or dot after Island Pro. Keep those labels together rather than claiming a fixed dot number as official.
  • The official announcement confirms Version 1.0 multiplayer and host rules, but it does not name Smooth Sailing as the universal unlock condition.
  • A console result may not reproduce a Steam / PC result without a platform-specific test.

Community walkthrough checklist

The Steam guide gives the most actionable current checklist: Island Life app, six named milestones, and Smooth Sailing after meeting all mentors and helping Marston build the Maritime Bureau. Two independent public quest references describe the same Smooth Sailing and Maritime Bureau relationship, but the exact universal gate is still labeled Community report until an official source or repeated current-build tests confirm it.
