Golden Harvest
Help Custard Cookie III harvest goods from the Sea Farm and trigger synergies for Golden Cheeseballs.
Golden Harvest is a roguelike deck-building mode where you use Cheese Pieces to produce items at the Sea Farm and harvest Golden Cheeseballs through synergies between various types of items. Build your product list, select Cookie buffs, and reach each round's Golden Cheeseball goal to advance.
Basic gameplay
- Golden Harvest is played over 15 rounds; each round you can harvest items a set number of times.
- After harvesting, select one of 3 item options to add to your product list (from Round 11 you may skip the selection stage).
- Meeting the round's Golden Cheeseball goal consumes that amount; any remaining Golden Cheeseballs carry over to the next round.
- Clearing all 15 rounds ends the game.
Sea Farm and product list
- Place items across the 4x4 space of the Sea Farm.
- Only items with a weight of 1 or higher appear in the product list and the Sea Farm; the higher an item's weight, the greater its chance of appearing.
- By selecting certain items you can increase the weight of a specific category, building a product list that makes your preferred items appear more frequently.
Synergy system
- Synergy: earn additional Golden Cheeseballs when items produced in the same building are adjacent.
- Power Synergy: when materials required for production are adjacent to the related goods, earn even more Golden Cheeseballs while those materials are consumed.
- The more synergies activated, the easier it is to achieve the round's objective.
Reroll and Remove Tokens
- Reroll Token: draw 3 new production item options. Remove Token: remove an item of your choice from your product list.
- Each is awarded x1 at the start of Rounds 3, 7, 11, and 15.
Cookie buffs
- Clear a round to choose one of 3 Cookie buffs, lasting for the current game.
- Effects include increased item appearance chance, bonus Golden Cheeseballs, synergy bonuses, automatic ingredient replenishment, and item consumption prevention.
Finishing the game & rewards
- The game ends when you fail a round's goal, choose to end after clearing a round, or clear Round 15.
- The higher the round you clear, the more cumulative rewards you earn; Cheeseball Coins are earned proportional to the Cheese Pieces used.
- Cheeseball Coins can be exchanged for various items at the Golden Harvest shop.
Practice Mode and Regular Mode
- Practice Mode: no rewards, but unlimited play to practice item combinations and synergy builds.
- Regular Mode: your season record is saved based on the total Golden Cheeseballs collected in a single game.
