Sunshine Islands Bus Simulator (players call it SIBS) is a free Roblox game about driving a scheduled bus service across a fictional Hong Kong-style archipelago. You pick a route, work a shift, stop at every scheduled stand, open the doors, let AI passengers pay and sit down, then deliver them on time. Miss a stop or slam the brakes and they complain; finish clean and you earn experience, Sunshards and access to more of the map.
The city is not a backdrop: 10 islands across 8 zones, four strategic highways, tunnels, bridges and mountain roads, numbered the way a real transit authority numbers them — the first digit is your zone, the last one is your destination.
The five things players ask about most
| Question | Short answer |
|---|---|
| Is it free? | Yes — free on Roblox, PC, mobile and console. |
| How many routes? | 5 operators and 21 routes on the official site; 50+ routable numbers once branches, peak and night variants are counted. |
| How do routes unlock? | Level up by finishing shifts; special routes cost Sunshards. |
| What resets daily? | Daily Tasks and Daily Challenges, at 00:00 UTC / 08:00 HKT. |
| Where do I start? | The beginner guide, then an inner-zone route — the two-digit ones. |
What to do in your first ten minutes
- Pick a shift on a two-digit inner-zone route (41, 42, 46, 47, 75). Inner-zone runs stay on one island group, so the layout is far easier to learn.
- Press P for the parking brake, start with W, and W becomes the accelerator once you roll.
- At the first stand — within about 7 metres — the game asks for the brake and the front door (K). Nobody boards until you open it.
- Wait for boarding, close up, and watch for the bell: passengers ring it at their own stop, so the next stand is on you.
- Finish without skipping a scheduled stop. Skipped stops are what silently cost you rewards.
How the route numbers work
- Two digits = inner zone (4x is Zone 4, 7x is Zone 7); three digits = inter zone (475 runs Zone 4 to Zone 7).
- Prefixes change the service type: N overnight, R event, S sightseeing, U university, C and F staff shuttles, Y typhoon diversion.
- Suffixes change the pattern: X express, P peak only, R event extra, Y typhoon replacement.
Game modes at a glance
Shift is the core loop. Free Drive drops the schedule and lets you set the time of day. Daily Challenges and Community Servers (up to 100 drivers) both unlock at level 10, while almost every vehicle is available from your first shift — see the servers guide for what changes where.
