🧠 Tic-Tac-Toe Distinct Legal Move Dataset

📘 Overview

This dataset contains all possible legal Tic-Tac-Toe game sequences — that is, every unique path through the complete game tree (about 255,168 distinct sequences) from start to finish.

Each row represents one move in one possible game, with metadata like:

Which player made the move
The board state before the move
The move position
The final game result (Win/Loss/Draw)
A symmetry_id that groups equivalent boards under rotations and reflections

This dataset can be used for machine learning experiments, game theory analysis, or reinforcement learning training.

🧩 Dataset Structure

Column	Description
`game_id`	Unique identifier for each full game sequence
`step`	Step number within the game (1–9)
`player`	`X` or `O` — the player who made the move
`board_state`	The board represented as a 9-element list (1 = X, -1 = O, 0 = Empty)
`next_move`	The index (0–8) of the next move in the flattened 3×3 grid
`result`	The final outcome of the game (`X Win`, `O Win`, or `Draw`)
`board_state_str`	Human-readable board string (e.g., `X,_,_,O,_,_,_,_,_`)
`symmetry_id`	A hash of the canonical form of the board after accounting for rotations/reflections

🔍 Example

game_id	step	player	board_state	next_move	result	board_state_str	symmetry_id
1	1	X	`[0,0,0,0,0,0,0,0,0]`	0	X Win	`_,_,_,_,_,_,_,_,_`	812347823
1	2	O	`[1,0,0,0,0,0,0,0,0]`	4	X Win	`X,_,_,_,_,_,_,_,_`	982734987
1	3	X	`[1,0,0,0,-1,0,0,0,0]`	8	X Win	`X,_,_,_,O,_,_,_,_`	123459812

🧮 Data Generation Logic

The dataset was programmatically generated by exploring the complete Tic-Tac-Toe game tree using recursive backtracking in Python.

Key features:

Symmetry normalization: Boards that are identical under rotation/reflection are reduced to a single canonical form.
Comprehensive coverage: Every legal sequence is included.
Direct serialization: Each move is written as a CSV row for efficient analysis.
