No.237Stardew Valley01The core loop
Action → feedback → next choice- 01Place the trap
- 02Bait it and leave
- 03Let time pass
- 04Collect and reset
↻Feedback changes the situation — the next round starts from there.
Walk through one round
A simplified design example. Situations and numbers illustrate the mechanic, not exact rules from a reference game.
- T1
Turn 1 · The situation
The player has 4 crab pots, each yielding 1 item per night; sea and river catches differ.
- T2
Turn 2 · The player chooses
Three go by the sea, one by the river, all baited.
- T3
Turn 3 · The feedback
Next morning: 3 crabs, 1 crayfish and some trash in one pot.
- T4
Turn 4 · The next decision
They buy 2 more and line them along their daily route.
How it plays
Traps accumulate catches over time without the player present. Count, bait and location set yield, while collection routes and timing are the main planning. Some traps degrade or attract trouble if left too long.
What the player weighs
- More traps vs. lower cost and upkeep
- Remote prime spots vs. convenient spots on your route

03One mechanic, different implementations

Stardew Valley
Baited crab pots produce shellfish or junk daily, with water type shaping results; a fishing profession removes the bait requirement and junk.

DREDGE
Crab pots are deployed from your boat and retrieved after in-game time; leaving them too long reportedly causes degradation, and the water type sets the catch.
The difference worth noticing
Stardew's pots fit the daily farm routine; DREDGE's must be planned around routes and night-time danger.

04What could you combine?
Traps can only be placed in waters you've personally charted, so exploring first unlocks new trap lines on your map.
