❌ Tic Tac Toe
Tic Tac Toe dates back to ancient Egypt around 1300 BC. The Romans played a version called 'Terni Lapilli.' The modern 3×3 grid version has been mathematically solved — with perfect play from both sides, the game always ends in a draw. Despite this, it remains a beloved game for children and a classic introduction to game theory and AI programming.
