Shells become buying power
The public game description confirms that crabs dig shells and shells turn into cash. Exact exchange rates can vary by visible in-game state, so the calculator asks players to enter their own rate.
Shells and Cash
Shells are the visible production resource in Crab Tycoon. Your crabs dig them up, then shells can be turned into cash for more crab production.
Use a one-minute shell test
After a purchase or merge, watch the shell counter for one normal minute. That gives a practical shell-per-minute input for planning the next cash target.
No hidden formula claims
This wiki does not publish exact shell multipliers, cash formulas, or price tables until those values are live-verified and source-backed.

Turn shell data into a decision
Use the planner after recording your visible shell rate. Compare open slots, duplicate crab pairs, and offline shell claims before spending cash.
