Sharks and Reefs expands upon Finspan’s simple, approachable gameplay
Finspan: Sharks and Reefs is a “no bloat” expansion that feels pretty clear in what it wants to offer: a richer, more varied version of the base game built around a single new mechanism that integrates cleanly into everything that we already enjoyed.
Sharks and Reefs adds variety through a large deck of new fish cards and depth through the introduction of a relatively simple coral reef mechanic, but it never overwhelms or disrupts the flow of play, and it makes no fundamental changes. Instead, Sharks and Reefs enhances the core experience in ways that feel natural, intuitive and on occasion, clever.

The most visible addition is the new reef overlay that sits on top of each player’s ocean mat. This introduces three coral reef habitats — one for each dive site — and each habitat can be populated with coral tokens. These tokens come in three colours and are earned through actions you’re already taking in the game, so the expansion doesn’t bolt on extra steps or bookkeeping that makes it fiddly. Instead, the coral system becomes an additional. satisfying puzzle layered onto your existing engine. Healthy reefs allow you to play powerful reef fish, unlock additional abilities and score end‑game bonuses, giving you a new axis of optimisation without changing Finspan’s core ideas.
Sharks and Reefs also includes a substantial deck of new fish cards — 75 new fish plus 5 new starter fish. These cards focus on sharks and reef‑dwelling species, and they broaden the tactical landscape considerably. Sharks behave differently from most fish in the base game: they scatter schools of young, creating new opportunities elsewhere and converting a school of three into four individual young.. Reef fish, meanwhile, tie directly into the coral system, rewarding players who invest in building up their reefs. The new starter fish offer fresh opening strategies that support these ideas, and the expanded card pool increases variety and replayability without diluting the simple clarity of the original design.

Solo players receive meaningful support through updated automa cards and revised solo rules. The automa now interacts with coral reefs and the new fish abilities, ensuring that the solo experience remains balanced and fully compatible with the additions in the Sharks and Reefs expansion. The inclusion of a dedicated solo rulebook makes this mode easier to reference and smoother to run, and as we’ve become accustomed to, the Stonemaier automa system remains one of the best ways to experience a game solo.
A number of thoughtful quality‑of‑life improvements underpin the quality which (again) we’ve become used to from Stonemaier. The expansion includes new player aids that explain the additional symbols and interactions introduced by sharks and reefs, helping players integrate the new content without slowing down the game and there’s even a new organiser tray which holds all the cards from both the original game and the expansion. This tray fits neatly into the existing box alongside the original tray, making setup and storage noticeably cleaner, although as someone who also has the “fancy” upgraded components and doesn’t wish to bin the originals, I have to say that my box is pretty much at its limit now.

There are also new achievement tiles and an updated achievement board, expanding the long‑term goals available in each play and obviously integrating (or not) the new mechanics depending on how you choose to select your achievements. I was quite pleased about how these specific goals have been designed, because I always felt with Wingspan that the more expansions were added, the more diluted and unpredictable the scoring became. There are fewer scoring tiles here, and I feel that they “hit” a broader number of possibilities in the game, which means that unlike in Wingspan, all strategies remain viable with Sharks and Reefs in the mix.
This leads me to my closing thoughts, and what stands out most about Sharks and Reefs is how seamlessly it fits into the base game. The coral system adds a new layer of decision‑making, but it never feels intrusive or overly complex. The new fish cards enrich the card ecosystem in ways that feel organic, and the shark abilities introduce fresh interactions without disrupting the game’s gentle pacing. Everything here feels like “more of what we love,” with just enough mechanical novelty to make the experience feel refreshed and new.

For players who already enjoy Finspan, the Sharks and Reefs expansion is an easy recommendation. It deepens the game without complicating it, expands the card variety, strengthens solo play and adds tactile new elements through the reef boards and coral tokens all of which I felt was additive to the game without any unnecessary faff.. It’s a well‑judged, generous expansion that enhances the base game in all the right ways.
