This Python scripts generates a playable HTML-only Tic Tac Toe game. The generated file is 560KB, that is more than 300 times smaller. Also it works in any browser not just Chrome, probably even TUI browsers like w3m or links for that matter ^^. It generates all and only the valid game states, that is 5478 boards. It may be optimized further.
