How the game works
Summary
You build up a cannon by buying explosives, barrels, and parts from the shop, then fire it to see how far the cannonball travels. Obstacles appear during flight, and steering around them keeps you airborne longer. When the shot lands, you collect cash based on the distance. Spend that cash on upgrades and repeat.
- Explosive determines the power and distance of each shot
- Barrel changes how the explosive performs when fired
- Parts small upgrades that improve the cannon's overall performance
- Cash the currency you earn from every launch, used to buy everything in the shop

Steering during a launch
Tips
Once the cannonball is in the air, obstacles start appearing on both sides. Hitting one ends the flight immediately, so staying alert matters.
- Steer left or right the moment an obstacle comes into view
- The path changes every launch, so you cannot memorize a fixed route

Common questions
FAQDoes the game keep earning cash when I am offline?
Yes — your cannon fires automatically even when the game is closed, and the cash it earns waits for you when you log back in.
Can I complete the whole game without paying real money?
Yes, every item in the shop can be purchased with cash earned through normal play and offline firing. Real-money purchases only speed up the process.
