Hunting
Use your weapon to hunt ducks. Weapon power sets how fast you clear each shot.

Systems & Progression
The four systems that drive the Catch 1 Billion Ducks loop, and how they connect to your daily decisions.
Selling
Your dog retrieves ducks and sells them for coins. Retrieval speed sets the loop cadence.
Upgrades
Spend coins on a visible upgrade. Test one change at a time and read the new value.
Reserves
The protected buffer of coins you never spend, so you can always buy the next upgrade.
The five-stage loop
Catch 1 Billion Ducks runs a continuous cycle: gear up with a weapon → send your dog → hunt ducks → sell for coins → buy a visible upgrade. Every system feeds the next, so a decision in one stage (like spending your coin reserve) can block a later one (like affording the next weapon).
Upgrade costs and duck values can shift with updates. Confirm the live numbers before any big spend.
