Review: Enso

Introduction & Overview

Enso is a game inspired by the Zen concept of the Enso (円相): the circle drawn by Zen monks. Players move their stones and capture their opponent’s, aiming to position one of their stones so that it is surrounded by open spaces in eight directions, as if enclosed within a circle. What makes this game unique is that the moves a stone can make depend on whether it is adjacent to opponent stones.

This is the premise behind Enso, a design by Dieter Stein (Urbino, Volo). First published in 2026 by Kanare_Abstract in a bilingual English and Japanese edition, with cover illustration handled by Kanare Kato.

It is not published in Spain, so you will have to turn to the import market (the game is completely language-independent). It supports 2-player games, with a suggested minimum age of 10 and an approximate running time of 30 minutes. The MSRP is €20.95. For this review, we used an English and Japanese copy from Kanare_Abstract, kindly provided as a review copy by the publisher itself.

How to Play

Enso is an abstract strategy game for two players inspired by the Zen concept of the hand-drawn monk’s circle, where the main objective is to successfully isolate one of your own stones so that it is surrounded by eight empty spaces in all directions. The game is played on a gridded board where participants alternate turns, with the player controlling the black pieces always going first. On each turn, the active player must move one of their stones in a straight line, either orthogonally or diagonally, traversing any number of vacant squares without jumping over other pieces. The game’s defining twist is that movement options are strictly dictated by adjacent pieces at the start of the turn: if the chosen stone touches at least one opposing piece, it is forced to make a capture by occupying its square; if it is adjacent solely to friendly pieces, it may only move to a space that touches an enemy piece or to a completely isolated square, with no option to capture; lastly, if it touches no other piece whatsoever, it is not permitted to move. The game ends immediately, awarding victory to the player who manages to form an “Enso” (even if triggered by an opponent’s move), or via defeat for any player unable to make a legal move on their turn.

Key Concepts

Let us start with the Board. It consists of a six-by-six grid where the entirety of the game takes place. The squares accommodate player pieces and establish orthogonal and diagonal adjacency relationships between them across up to eight directions. The sixteen inner squares, highlighted in a distinct shade, are worth noting, as they are essential to the victory condition.

On the other hand, we have the Discs, which start directly on the board. Players alternate turns moving one of their discs in a straight line (orthogonally or diagonally) across any number of empty spaces without leaping over other pieces. The movement options for each disc depend on its adjacency status at the start of the turn: if it borders opposing pieces, it must capture by occupying an enemy space and removing that piece; if it only borders friendly pieces, it can only move to squares where it ends up adjacent to enemy pieces or completely isolated; and if it has no adjacent pieces, it cannot move at all. The primary objective is to leave one of your discs entirely isolated, that is, surrounded by eight vacant spaces around it.

That is enough to get started.

Preparación de la Partida

Place the board in the center of the table.
Each player chooses a color and receives the corresponding 16 tokens.
Place the tokens on the board following the starting layout: occupying the four 3×3 corner quadrants while leaving the 4 central board squares empty. One player arranges their tokens in the top-left and bottom-right quadrants, while the other occupies the top-right and bottom-left quadrants (leaving the inner corner of each quadrant empty).
The player controlling the black tokens is the starting player.

We are ready to begin!

Game Flow

A game of Enso unfolds over an indeterminate number of turns alternating between players, starting with the player controlling the black pieces.

On their turn, the active player must move one of their pieces. Any piece can travel across any number of empty squares in a straight line along any of the eight directions (orthogonally or diagonally). Pieces cannot jump over other pieces along their path.

However, the legal movement options for a given piece depend entirely on the type of adjacency (across all eight directions) it features at the start of the turn:

If the piece is adjacent to at least one opponent piece: it must make a capture. To capture, the piece moves into the square occupied by the targeted opposing piece and replaces it on the board, removing it from play.
If the piece is adjacent exclusively to pieces of its own color: it cannot capture. It may only move to a space adjacent to one or more opposing pieces, or to a space where it ends up completely isolated (with no pieces of either color in its eight surrounding squares).
If the piece is not adjacent to any other piece: it is isolated and cannot perform any move.

After moving the piece (and resolving the capture if applicable), the turn passes to the opposing player.

Game End

The game ends immediately if either of the following conditions is met:

Victory by Enso. If a player manages to leave at least one of their pieces completely isolated (surrounded by eight empty squares in all eight possible directions), that player wins the game immediately. This can happen through their own move or via an action carried out by the opponent. If a move causes both players to meet this condition simultaneously, the player who just took their turn wins.
Defeat by stalemate. If the active player cannot make any legal move on their turn, they lose the game immediately.

Personal Opinion

Abstract strategy games possess an inherent purity rarely found in other board gaming genres. Stripped of all fluff, they stake everything on the elegance of a minimal ruleset capable of delivering tremendous strategic depth. It is fascinating how mechanics learned in barely two minutes can unleash such rich tactical dynamics, where every single move carries far-reaching consequences down the line. While many contemporary designs require layer upon layer of sub-systems to present a demanding challenge, a great abstract proves that less is more.

In this regard, the dedication of the few publishers still genuinely committed to the genre is truly commendable. In an industry currently dominated by overproduction, sprawling table footprints, and visual spectacle over mechanical refinement, maintaining a catalog centered around these titles is a monumental task. Imprints like Gigamic, Cosmoludo, or Gerhards Spiel und Design deserve praise for swimming against the tide, proving that there is still a loyal audience that values restraint, the tactility of noble materials, and the sheer delight of a sharp intellectual tabletop duel.

To this select group of bold outfits, one must add Kanare_Abstract, a Japanese imprint that has devised an exceedingly clever approach to overcome standard distribution hurdles. Fully aware of how prohibitive shipping bulky boxes and heavy components from the Far East can be today, the publisher has opted for a compact, minimalist format that shrinks logistical costs to a bare minimum without compromising the gameplay experience. This practical approach enables them to ship these titles worldwide at competitive prices, making their catalog remarkably accessible to abstract gaming enthusiasts everywhere.

As you might have guessed, today we are taking a close look at one of these designs coming out of the Japanese publisher’s pipeline. Let us see how this Enso fares on the table, not before thanking Kanare_Abstract for providing the review copy that makes this long-running write-up possible.

The term Ensō has its roots in Japanese Zen calligraphy, standing as one of the purest and deepest expressions of its philosophy. It involves drawing a circle in a single, fluid, uninterrupted brushstroke to capture wholeness, enlightenment, the void, and the inherent beauty of imperfection. Far from aiming for geometric precision, this traditional symbol reflects the inner state of the master setting it down on canvas, allowing the mind to let go of worldly distractions and embrace the present moment. It is an allegory of balance, where fullness and nothingness coexist in complete harmony.

Mechanically, the design takes place on a six-by-six grid where each contender manages sixteen discs, each able to move in a straight line along any of the eight orthogonal or diagonal directions across any number of unoccupied squares.

The defining twist, however, lies in how the immediate surroundings of a chosen piece dictate its mobility. Movement depends on whether the piece is in contact with enemy and/or friendly pieces. If a disc starts the turn touching one or more opposing pieces, it is forced to execute a standard capture whenever moved, sliding into the square of one of those enemy pieces and removing it from the game. Conversely, if it borders only friendly pieces, it can move without capturing, though it must end its movement either on a space adjacent to at least one opposing piece or completely isolated with no neighbors.

Finally, if a piece is already isolated at the start of a turn, it cannot be moved under any circumstances. This last restriction ties directly into the victory condition giving the game its name. The goal is to maneuver one of your pieces into complete isolation within one of the sixteen central squares of the board—meaning it is surrounded by eight empty spaces—forming that circle of solitude reminiscent of the Zen ensō.

Curiously, this milestone can be achieved through your own actions or as an involuntary byproduct of an opponent’s move when capturing or vacating neighboring squares. It yields a high-tension tactical race where prying open gaps and setting traps is just as vital as managing mutual gridlock. And that is practically all there is to it.

With sufficient context out of the way, we can dig into the dynamics and table feel. One of the most common dilemmas players face arises whenever a friendly piece touches an opposing disc. Activating that token forces a capture, yet one must proceed cautiously, as doing so can easily walk straight into a trap. Devouring an enemy piece along that line often leaves your disc surrounded exclusively by friendly pieces on the following turn. While an immediate threat has been neutralized, an aggressive piece becomes passive, draining your offensive momentum if the opponent knows how to regroup.

The flip side of the coin comes when maneuvering pieces that only touch friendly units. Here, calculation becomes fiercely demanding. Suppose a player has a white disc in the second row aiming for the center. The ideal outcome would be slipping into an empty square to threaten victory, but sightlines are routinely blocked. The player is forced to move toward a square adjacent to a black piece, offering themselves up as a mandatory capture or prompting a trade that clears out the pivotal space they need vacated.

The true climax of a match is reached as the board thins out and the psychological tension of isolation takes over. Consider a board state where a player has a piece flanked by two occupied neighboring squares. Should the opponent err by capturing one of those satellite pieces instead of pivoting away or repositioning, they might inadvertently leave that target completely alone, handing over the win on their own turn. This dynamic demands that every retreat be measured down to the millimeter to avoid giving away free openings—something that sounds straightforward enough, yet player impatience regularly leads to fatal blunders.

As you can see, this is a clean design whose greatest strength lies in generating depth through a simple concept: altering a piece’s movement options based on its surroundings. Every turn presents a dynamic puzzle where reading the neighborhood around each disc becomes a stimulating challenge. Players must continuously weigh whether pushing toward enemy lines to trigger future captures makes sense, or whether holding a piece alongside friendly ranks is preferable to reposition and menace open ground.

On the flip side, this design quirk introduces a noticeable barrier to entry across initial plays. The three distinct movement scenarios—whether a piece borders enemy units, touches only friendly pieces, or sits completely isolated along an edge—feel counterintuitive at first, particularly once diagonal spaces enter the equation, as most players naturally default to orthogonal evaluation.

Another hurdle that tends to surface during early games is the difficulty of plotting a long-term plan during the opening. Starting with thirty-two pieces crammed onto a board of barely thirty-six spaces gives the opening rounds a distinctly constrained feel, forcing players into early trades. Spotting a clean strategic vector proves challenging without feeling like any push inadvertently hands an advantage to the opponent.

Yet that apparent early friction quickly morphs into an electrifying psychological tug-of-war. Once past the initial learning curve and attuned to the subtleties of the grid, Enso reveals itself as an elegant and deep design where every capture reshapes threat vectors across the entire board. It is precisely that shift in perspective that elevates the title.

While perhaps not quite as striking as other straight-line grid movement abstracts such as SHŌBU (read its tocho-review here) or Triad (read its tocho-review here), that tight, claustrophobic initial setup remains engaging enough to earn the game repeated table time.

Regarding production, the set includes a satin fabric board (characteristic of the publisher’s lineup). The wooden discs boast good thickness, making them easy to slide across the surface. The rulebook is logically structured and leaves no ambiguity. As expected, the packaging adheres to the publisher’s signature style since day one: a minimalist white cardboard box with a cover sticker and a clean white rear face. Functional, if not particularly eye-catching on retail shelves.

And let’s wrap this up. Enso is an understated abstract design that makes excellent use of a tight grid where discs move along straight vectors and find their options governed entirely by neighboring pieces. The mandatory capture rule when bordering enemy units paired with the pursuit of central isolation sparks a taut duel, forcing players to calculate every move carefully to avoid handing their opponent victory on a silver platter. The game excels at delivering a demanding mental duel from a minimal ruleset, shifting smoothly from a congested board into a sparse, dramatic endgame. On the downside, the three-pronged positional movement feels counterintuitive in early plays, compounded by a somewhat rigid opening phase where charting a long-term plan without falling into forced trades is no easy feat. All told, an exceptionally elegant and stimulating design. For all these reasons, I give it a…
