Review: Lost Seas
Introduction & Overview
Terrible tales are told of the mysterious, uncharted depths of the lost seas. Rumors abound of gigantic krakens, hellish whirlpools, immense sea serpents, and hostile deserted islands where only the skeletons of ancient shipwrecks remain as testament to failed expeditions. The time has come to gather your navigational instruments and embark on your most ambitious expedition yet. If you succeed, you will attain glory beyond your wildest dreams, and your map will become the stuff of legends.
This is the premise behind Lost Seas, a design by Johan Benvenuto (Harmonies, Secret Identity) and Alexandre Droit (Hiroba, Gloobz). First published in 2022 by Blue Orange in a multilingual edition, it is a re-theming of Market Garden (released that same year by the same publisher). The artwork was handled by Marine Joumard, marking her debut in the board game industry.
It is available in Spain as Día de Mercado through Lúdilo (although the Blue Orange edition includes Spanish rules, and the game is entirely language-independent). It accommodates 2 to 4 players, with a recommended minimum age of 7, and plays in approximately 20 to 30 minutes. The retail price is €21.90. A copy of the multilingual edition by Blue Orange was used for this review.

Components
Inside a two-piece cardboard box (lid and bottom) measuring 20×20×5 cm (a small square box similar to Kahuna or Patchwork), we find the following items:
- First Player Marker (wooden)
- 65 Sea Exploration Tiles (cardboard)
- 44 Double-Sided Expedition Tiles (cardboard)
- Rulebook
How to Play
Lost Seas is a game combining drafting, tile placement, and pattern building in which each player builds a four-by-four grid of tiles. At the beginning of the game, each player receives 8 expedition tiles divided into two groups of four (the first set placed along the top row and the second down the left column). Each expedition tile is double-sided, featuring an easier side with white banners and a more demanding side with black banners. Sixteen rounds are then played. In each round, starting with the first player, everyone drafts one sea exploration tile from the five available in a common display. The selected tile may be placed on any empty space within the player’s grid. The game ends once the grid is fully completed, at which point all eight scoring criteria are evaluated, and the player with the most victory points wins.
Key Concepts
There are two types of tiles. First, the Sea Exploration Tiles feature a blue ocean background on a grid, displaying one to three symbols from six possible elements: sea serpents, storms, ghost ships, deserted islands, krakens, or rocks. A single tile may show multiple symbols of the same type. Players will use these tiles to assemble a four-by-four grid in their personal play area.
Along the top row and the leftmost column of this grid lie the Expedition Tiles. These are double-sided tiles on a yellow background that depict a scoring condition or requirement, with the top-left corner indicating the victory points awarded (either multiplied by the number of times the condition is fulfilled, or as a flat score if the requirement is satisfied). Each tile presents a different objective, distinguished by the banner color showing the point value (white on the easier side, black on the harder side). Players receive these tiles at setup and decide individually which side to play.
That is enough to get started.
Preparación de la Partida
- Shuffle all expedition tiles and deal four to each player.
- Each player arranges these four tiles into a row, choosing whichever side they prefer for each one.
- Deal another four expedition tiles to each player to form a column to the left of that row, establishing a five-by-five grid with the top-left corner left empty. Once again, each player chooses which side to place face-up.
- Shuffle the sea exploration tiles and form a face-down draw pile in the center of the table.
- Reveal the top five tiles from the deck to form a market display.
- Randomly choose a starting player and give them the first player marker.
We are ready to begin!
Game Flow
A game of Lost Seas is played over sixteen rounds. In each round, beginning with the first player and proceeding clockwise, each player drafts an available tile and adds it to any empty space in their grid.
- In three-player games, after drafting their tile, the first player must also select a second tile to discard from the game, returning it to the box.
- In two-player games, the second player does the exact same thing after drafting their own tile.
Once every player has selected a tile, one will remain in the display. Keep it there for the next round and reveal four new tiles to refill the market. Pass the first player marker to the player on the left, and begin a new round.
Game End
The game concludes after the sixteenth round, once every player has completely filled their grid. Each player then scores every row and column, adding the corresponding points if the objective has been fulfilled. The player with the highest total score claims victory. In the event of a tie, resolve it using the following criteria:
- The player who fulfilled the requirements on the highest number of expedition tiles.
- The player who scored the highest points from a single expedition tile.
If a tie still persists, victory is shared.
Variants
Simplified Game. Expedition tiles are not used. Form a market display of three sea exploration tiles and replenish it immediately whenever the active player takes one. For each row and column, the player scores 1 point for each sea element that forms a majority within that specific row or column (regardless of what opponents have).
Personal Opinion
As you well know, the go-to mechanical combination for publishers targeting mainstream audiences is drafting paired with tile placement and pattern building. It represents a safe bet that consistently delivers an engaging challenge for several reasons.
On one hand, it functions as a personal puzzle where players must find the optimal placement for the pieces acquired through the draft. On the other, it introduces just the right touch of player interaction through an accessible drafting mechanism where everyone evaluates the best available option based on competing scoring criteria.
The drawback is that publishers and designers lean into this formula far too frequently, knowing it rarely fails and almost always yields an acceptable result. Stepping outside that comfort zone is tough, making it increasingly rare to find a design capable of standing shoulder to shoulder with the established benchmarks of the subgenre.
Today, however, I am reviewing one of those rare attempts. It is a title that seems to fly completely under the radar without appearing on anyone’s favorites list. Was it overlooked because it is purely mediocre? Or are we dealing with one of those genuine hidden gems tucked beneath the surface? Let us find out by exploring everything Lost Seas brings to the table.
The first thing that strikes you about this game is its sheer elegance. Despite floating in a vast sea of titles built on drafting, tile placement, and pattern construction, Lost Seas sets itself apart by taking the opposite route of most modern designs: stripping away conceptual overhead to an absolute minimum.
As anyone who read the rules section will have gathered, Lost Seas is disarmingly simple. It can literally be taught in five minutes, and games wrap up in under half an hour because they consist of just sixteen straightforward rounds where players draft a tile from a shared display and fit it into their grid.
That grid is bounded at setup by objective tiles that define specific scoring criteria for each intersecting row and column. The gameplay revolves entirely around filling the board as efficiently as possible to trigger every single condition.
It sounds elementary on paper, so where does the fun come from? It hinges directly on that opening phase where players receive their scoring criteria. Each tile is double-sided, offering an easy requirement on one face and a considerably steeper demand on the other.
Players build their own puzzle constraints in two distinct steps: laying out the row first, followed by the column. While that process might seem trivial, its impact is enormous. Isolating a single row in your mind is an easy trap to fall into, whereas the genuine challenge lies in visualizing how the entire finished grid must look to satisfy both axes simultaneously.
For instance, placing a tile in a row or column that demands an exact number of total elements (regardless of their type) forces you to draft a specific breakdown across those four slots, such as 1-1-1-3 or 1-1-2-2. While the order of those tiles may not matter for that single line, it matters immensely for every perpendicular objective crossing it.
If an intersecting column demands a heavy concentration of a specific icon, you suddenly find yourself pigeonholed into needing a highly specific exploration tile in that exact coordinate.
This dynamic introduces two clear hurdles. First, even with duplicate tiles in the deck, the odds of drawing the exact piece you desperately need right on your turn are slim. Second, since all grids and objectives are open information, earlier players in turn order can easily hate-draft the exact piece you need to stay on track.
There is nothing more to it, and it does not need anything else. Lost Seas fits squarely into the filler category, meeting my personal criteria for the label: a rules explanation and a full playthrough easily fit within thirty minutes.
Being a filler is hardly a flaw; if anything, it is its greatest strength. At their core, games like Calico (tocho-review here) or FYFE (tocho-review here) share the same underlying loop of filling grid slots with tiles to satisfy intersecting patterns. Yet those titles tend to lean toward the family-weight category due to their larger footprints and slightly heavier rulesets.
That streamlined profile makes Lost Seas feel superior to many of its peers. It cuts out all excess fat, confronting players with non-stop, meaningful decisions. The setup alone shapes the entire trajectory of the match, turning every draft phase into a nail-biting dilemma.
You will run into agonizing turns where none of the available tiles suit your layout. Alternatively, you might spot an ideal tile only to find its natural placement blocked by an earlier placement mistake. Every compromise stings, because jamming a suboptimal tile into your grid often torpedoes an entire row or column’s scoring potential.
I also appreciate the tight focus it demands from players. Tunnel-visioning on a single row while ignoring the broader state of your board is remarkably easy. Sooner or later, someone around the table groans after realizing a recent placement permanently ruined an intersecting objective.
Another area where Lost Seas shines is its mitigated luck factor. Every single sea exploration tile will enter play over the course of the game, regardless of player count. While games with fewer than four players feature occasional discards by earlier players in the round, you can always track whether a vital tile has already shown up or remains in the deck, enhancing tactical planning.
Speaking of player counts, Lost Seas is at its sharpest at two players. The level of player interaction doubles because drafting a tile also comes with discarding an additional tile from the display before your opponent acts. This lets players actively deny pieces that fit their rival’s grid like a glove. While it still functions smoothly at three or four players, two players offer the most vicious, balanced, and dynamic back-and-forth flow.
Replayability is also surprisingly strong. The brisk half-hour playtime leaves you feeling completely satisfied yet ready for an immediate rematch. Furthermore, the diverse pool of scoring tiles turns each initial setup into a fresh, rewarding spatial puzzle. Ambitious players can even calculate their maximum possible ceiling against opponents’ spreads to gauge risk, though committing fully to the high-difficulty sides across the board is outright suicide.
Turning to production values, the cardboard tiles boast solid thickness and dense punching, accompanied by a generously sized wooden first-player token. The rulebook is clear, concise, and leaves no room for ambiguity. Where the game stumbles compared to its direct competitors is in its visual presentation. While far from ugly, the aesthetic is fairly plain, featuring serviceable icons and an unassuming box cover that struggles to grab attention.
And let’s wrap this up. Lost Seas stands out as an elegant, highly effective filler that revitalizes a familiar trio of mechanics—drafting, tile placement, and pattern building—with lightning-fast turns and accessible rules suitable for any table. Its opening objective-drafting phase is a clear highlight where a single miscalculation can dismantle your strategy. It delivers sharper interaction than expected, particularly at two players where hate-drafting adds a delightful bite to every round. The reduced luck factor from seeing the full tile pool further elevates the experience. While the utilitarian artwork is uninspired and tactical missteps can lead to self-inflicted frustration, it remains one of the finest, most focused designs in its category, trimming away unnecessary bloat in favor of pure mechanical elegance. For all these reasons, I give it an…
