Increase good attempts
Rare collection progress comes from repeatable attempts. Favor eggs you can secure consistently, then reinvest the income into the route and upgrades that let you reach better targets.
- Secure a reliable income baseline.
- Improve the bottleneck: pool, base, or swim speed.
- Move to higher-risk targets gradually.
- Log each hatch instead of guessing odds.
Separate fish from modifiers
A fish can look exceptional because of its size or mutation. Compare like with like before deciding that a species is inherently rare or valuable.
Protect collection momentum
Do not carry a rare target through the busiest lane if a longer quiet path is available. One completed hatch adds more information and income than a failed shortcut.
