You can simply pass your list to the template. You can do without the conversion to JSON here.

return render_template('game.html', game=game, board=board)

To then use this variable in javascript, you can use the Jinja2 filter tojson. The result is your list as an array.

window.onload = start({{ board | tojson }});
