The basic loop
Step
The game gives you cash automatically every second based on how many generators you have and how upgraded they are. You spend that cash on more generators or on upgrading the ones you already own. Connecting generators into a larger power grid is what drives your earnings up over time.
- Buy a generator place it anywhere in your city to start producing power.
- Connect it link it into your power grid so it contributes to your per-second cash.
- Upgrade it spend cash to raise its output so each generator earns more on its own.
- Unlock new energy sources as you progress, higher-tier generators become available and produce more power.
Choosing and unlocking generators
Table
The game has multiple types of energy sources, and each new type you unlock outperforms the ones before it. Early generators are cheap, which makes buying several of them a reasonable start before you save up to unlock the next tier. You cannot build the biggest city without eventually moving on to more powerful sources.
| Early generators | affordable and easy to stack in large numbers quickly. |
| Higher-tier generators | unlocked as you progress and produce significantly more power per unit. |
| Large grid | only reachable once you have access to stronger energy sources. |
Growing your cash per second
Tips
Your cash income depends on both how many generators you have and how upgraded each one is.
- Adding more generators stacks their income together, so each new one raises your total directly.
- Upgrading a generator raises how much that single unit earns, which compounds across your whole grid.
Redeem codes
CheckThe game hands out redeem codes periodically. You enter them in a dedicated spot inside the game, and each code can only be used once per account. This site currently tracks four working codes, which are inserted live on the page.
- Find the code entry spot inside the game before trying to redeem anything.
- Each code works only once, so do not save them for later.

Common questions
FAQHow do I earn cash faster?
Buy more generators and upgrade the ones you already have — both actions raise your per-second income.

No. The game is built around solo play, and you can reach the biggest city entirely on your own. Servers hold up to six players if you want company, but it is not required.
Can I use a redeem code more than once?
No, each code can only be redeemed once. Use any code you find right away rather than holding on to it.
