What is Zone77?
Zone77 is a free online strategy game set in a clockwork city under the ground. You build a town, make resources, wind your machines with Energy, train soldiers and take the tunnels back from the Rust. Players team up in alliances, and the alliance that builds the Great Clock wins the season. Play in a browser or on Android.
Three factions
Brass Builders
Strong walls, full stores.
Rail Raiders
Hit fast, carry more.
Time Keepers
Every second counts.
Five resources
Coal
Iron
Water
Food
Gears
Mines, wells and farms make them; carts and the Market move them.
How you play
One town, one season, one alliance. Here is what you do in Zone77.
Build a town under the ground
Dig mines and wells, grow mushroom farms, house your workers and fill your stores. Every building takes time, and the timers keep running while you are away.

Wind your machines
Energy fills up over time. Spend it to speed up buildings and research, or to start a power. Wind gently and it is safe; push a machine too hard and it can jam.

Take the tunnels back
The Rust holds the tunnels around your town. Train soldiers, beat its camps for resources and Gears, and keep your Wall strong.

Race for the Great Clock
Late in every season, Great Clock sites appear near the center. Your alliance takes one and builds it level by level. The first to finish leads Zone77.

How a season works
Everyone starts together and a season ends with a winner. A Fast season lasts 6 weeks: short and quick. A Regular season lasts 18 weeks (about four months): long and calm. After the end the world stays open for a week of celebration. There is always one of each, and the next opens before the current one ends.
Step 1: Sign up early
A new season opens for sign-up before it starts. Choose your name, faction and place; your town is ready at the start.
- Fast
- Before the start
- Regular
- Before the start
Step 2: A safe start
Other players cannot attack a new town for its first hours. Build mines, storage and guards.
- Fast
- 3 days
- Regular
- 3 days
Step 3: Joining closes
In its last week the season is closed to new players. Until then, late arrivals get extra resources to catch up.
- Fast
- Day 35
- Regular
- Day 119
Step 4: The Great Clock appears
Great Clock sites rise near the center of the map. Alliances fight for them and start building.
- Fast
- Day 20
- Regular
- Day 70
Step 5: The season ends
The first alliance to finish the Great Clock wins, or the highest clock when time runs out. Then comes a week of celebration: the world stays open, and the next season is ready to join.
- Fast
- Day 42
- Regular
- Day 126
Questions players ask
Is Zone77 free to play?
Yes. Zone77 is free to play in your browser and on Android, with no ads. An optional Master Tinker subscription adds conveniences such as an extra safe speed-up, a longer building list and early alerts. If you never subscribed, you can start a 3-day free trial in the Android app, with Google Play.
Is Zone77 pay to win?
No. Master Tinker players do not get stronger soldiers or more resources, so everyone plays the same game. The subscription only saves time and clicks: a longer building list, saved armies, early alerts and pinned reports.
Can I play in a browser, or do I need the app?
Both work. Play at playzone77.com in any modern browser on a computer or phone, or install the Android app from Google Play (early access while it is in testing). It is the same account and the same town on every device.
How long is a season?
A Fast season lasts 6 weeks and a Regular season lasts 18 weeks (about four months). Fast seasons are short and quick; Regular seasons are long and calm. After the end the world stays open for a week of celebration, then it closes. There is always a Fast and a Regular season you can join, and the next one opens before the current one ends.
How do I join a season?
Create an account at playzone77.com or in the Android app, pick a season, then choose your name, faction and place on the map. You can join a Fast season during its first 35 days and a Regular season during its first 119 days. Players who join late get extra resources.
How do you win a season?
By building the Great Clock with your alliance. Great Clock sites appear near the center of the map late in the season (day 20 of a Fast season, day 70 of a Regular one). The first alliance to raise its Great Clock to level 77 wins; if nobody does, the highest Great Clock wins when the season ends.
How do alliances work?
Players team up in alliances to share a chat, send each other resources and soldiers, and race for the Great Clock. Build an Alliance Hall to level 3 to found one; each level of the leader’s hall makes room for more members, up to 30.
Will other players attack me as soon as I start?
No. New towns are protected from other players for their first 3 days, so you can build mines, storage and guards. Your protection ends early only if you attack another player yourself.
How much time does Zone77 take each day?
As much as you like. Buildings, soldiers and research run on timers that keep going while you are away, so a few short visits a day are enough. The Android app can notify you when something is ready or your town is under attack.
Why do I see "Request early access"?
Zone77 is in early testing. While sign-ups are limited, you can ask for a place and we email you when it is ready; a friend’s invite link lets you skip the waiting list.

Why Brass and Clockwork Suit a Strategy Game
Ideas for steampunk games begin with more than brass trim: clockwork can connect a strategy world's resources, geography and shared goals.
