Hexo Human Corpus

Encoding-free corpus of decisive human Hex Tac Toe games — hexagonal grid, six-in-a-row to win (player 1 opens with 1 move, then both players play 2 moves per turn; the board is theoretically infinite).

Each line is one game as a raw axial move list + outcome. Nothing about any neural-network encoding is baked in — no planes, no fixed board size, no action space. Read it with the stdlib json module and build whatever representation you want.

Files

file	description
`hexo_human_corpus.jsonl`	the corpus — one game per line
`SCHEMA.md`	full per-line schema + conventions
`dataset_metadata.json`	provenance: counts, sha256, source filter

Schema

One JSON object per line:

{"game_hash":"0f8c6bdfc55e7f6f","moves":[[0,0],[2,-2],[-3,3]],"winner":1,"source":"human","elo":[898,955]}

field	type	meaning
`game_hash`	string (16 hex)	SHA-256 of the move sequence — stable content/dedup key
`moves`	array of `[x, y]`	axial hex coords `(x,y)=(q,r)`, in play order
`winner`	`1` or `-1`	`1` = first player (X) wins, `-1` = second player (O)
`source`	string	`"human"`
`elo`	`[int\|null, int\|null]`	`[elo_p1, elo_p2]`

Conventions

Axial hex coordinates (x, y); the board is infinite so values can be negative. The first player's forced opener is always (0, 0).
Replay moves in order to reconstruct any board state.
Only decisive (six-in-a-row) games are included — there are no draws.

Usage

import json

games = [json.loads(line) for line in open("hexo_human_corpus.jsonl")]
g = games[0]
print(g["moves"], g["winner"])      # [[0,0], [2,-2], ...]  1

Provenance

Rated human games filtered to: rated, ≥20 moves, decisive by six-in-a-row. Per-game elo is each player's rating at game time. Games are anonymised (player ids dropped; only relative Elo retained). See dataset_metadata.json for the exact game count and sha256.
