Finspan Strategy

Overview

Finspan strategy is a 24-turn allocation problem. Every fish you play uses a turn that could have been a dive, and every dive uses a turn that could have placed a fish. Build a column worth revisiting, then convert that engine into visible points and population before week four ends. The suggestions below are editorial analysis of the base-game rules.

Week 1: get a reliable dive site running

Prioritize inexpensive fish that make a repeated dive useful. A colored fish may be powerful but limited to one column; an unrestricted fish can fill the weakest zone of a site. Think in terms of what the next two or three dives will yield, not only the card’s printed points. You start with eggs and young, so early hatching or card-flow effects can already have material to work with.

Count how often a fish will actually activate

A brown IF ACTIVATED effect pays only on dives through that site. A fish played early into a column you dive repeatedly can outperform a high-point fish that never triggers. Conversely, a late-game printed-point or WHEN PLAYED card may be stronger than an engine power with one possible activation left.

Fill useful zones before chasing a bottom bonus

A zone bonus requires a fish in that zone and site. A dive can pass through an empty zone but loses that bonus. The first dive at each site in a week has a separate bottom reward. Compare a populated site with repeated activations against spreading divers simply to collect three first-dive bonuses; the stronger line depends on your current fish and achievements.

Plan school production backward

A school replaces three young in the same slot and is worth six points at final scoring; three young alone would be worth three. You need egg placement, hatching and consolidation effects early enough for that three-point difference and any school-dependent abilities to matter. Do not force a school if doing so consumes several valuable actions that could score more elsewhere.

Watch the three achievement windows

Weeks 1–3 score achievements; week four does not. Evaluate whether an action increases this week’s category while advancing the engine. Side B’s extra three points go to the weekly high scorer, including ties, which can change a close decision. Check the actual achievement board before chasing generic “more fish” or “more eggs.”

Know when consuming is worth it

A larger fish can cover a shorter fish, including a printed forage fish, when the rules permit. The consumed fish scores only one point and does not remain a visible power, but the new card can bring a better ability, printed points or access to a key slot. Account for lost activations, transferred tokens and the new fish’s future dives together.

Week 4: buy points with your remaining turns

There is no later week to profit from an engine you build on the last turn. Count fish you can place legally, population that can still be converted, and GAME END conditions you can still satisfy. Keep cards in hand only if playing another fish would be weaker; hand cards also matter in the final tie rule.

Example decision

You have one dive left this week and can either trigger two egg effects in your strongest column or play a six-point fish in a weak one. If the eggs help win the active achievement, the dive may produce immediate points and future hatch material. If this is late in week four, the achievement is gone and the six-point fish may be the safer conversion. Compare those actual totals before following a fixed “always dive” rule.

Sharks & Reefs changes the site choice

The expansion adds coral reefs and requirements to consider alongside fish activations. Read the overlay and new card before deciding which dive site to develop; a base-game column plan may not meet a reef fish’s condition.
