Boards
Board style selects the topology. Width, height, markers, and stroke options further customize appearance.
Square grids
squares
squares-checkered

squares-stacked
squares-diamonds
heightmap-squares
Square grid with per-cell elevation for the isometric renderer.
Vertex boards
vertex
Go uses a vertex board with automatic star points. Disable with the hide-star-points option.

Top half only (half: "top"):
Bottom half only (half: "bottom"):
Alternating symmetry (alternatingSymmetry: true):
hex-of-tri

Example games: Conect
conical-hex-narrow
Example games: Conect
pyramid-hex
Circular boards
circular-wheel
Legacy interlaced style: pieces may be placed on vertices (even rows) or space centroids (odd rows). Row 0 is the outermost vertex ring; the final row is the centre point when circular-inner is 0. New games should prefer the explicit styles below.
circular-wheel-spaces
Spaces only — one row per ring. Row 0 is the outer ring, row height - 1 is the inner ring. Supports backFill, blocked, columnLabels, and circular-inner.
circular-wheel-vertices
Vertices only — intersection points at each ring radius. Row 0 is the outer ring. Supports backFill, blocked, and columnLabels.
circular-wheel-spaces-checkered
Like circular-wheel-spaces with alternating light/dark sector fills (no flood markers required). Optional startLight controls which ring/column parity is light.
circular-cobweb
Example games: Adere
circular-moon
Example games: Moon Squad, Adere
fractured-flat
Hand-authored fractured polygon board (45 cells). Rows are size tiers (triangles, quads, pentagons, hexagons). Columns sweep clockwise from north around the board center: each cell is ordered by the bearing of its first corner encountered by that sweep (minimum vertex bearing). Row 0 has 24 triangles, row 1 has 15 quads, row 2 has 5 pentagons, row 3 has 1 hexagon.
Index labels use a tier letter and 1-based column (A1 = row 0 col 0, B1 = row 1 col 0, etc.).
eleven
Football pitch board with 65 play spaces in a 1×65 grid (row = 0, col = topology index). Checkered grass, white pitch markings, green curved move connections, dashed shoot lines, and white-filled Felder rings with green strokes. Pieces are drawn larger than the rings (board.eleven.pieceScale); use a single pieces row of 65 cells (or comma-separated). Space highlights use flood markers on the marker layer over each Felder (polys), not piece cellsize.
Defaults match src/boards/eleven/source.svg: grass #aaea45 / #85d218, lines #559f00 at strokeWeight 3, white markings at 5/3× stroke weight. Nested options live under board.eleven (grass, flatGrass, markings, shootDashed, shootDash, pieceScale). Move/shoot lines are procedural quadratics trimmed to Felder rings (not traced from Linien); committed topology.json edgePaths (from npm run extract-eleven-board) supply Linien bulge direction at render time and are validated in tests. Tuning aids: npm run render-eleven-connection-debug → test/fixtures/eleven-connections-render.svg, npm run render-eleven-topology-debug for spaces/markers. Gameslib should map pitch ids or indices via @abstractplay/renderer/eleven (elevenResolveCell, elevenMarkerTarget).
