How to Play Tic Tac Toe IO
Control the center first: the middle square belongs to four winning lines, so opening there creates the most pressure. Watch for forks — two winning threats at once — and block them before they happen rather than reacting to one. Corner openings create the trickiest situations for your opponent, while edge openings are the weakest. When defending, prioritize moves that give yourself a threat at the same time. And against the bot, learn from its blocks: it will show you the lines you keep missing.
