In 1952, inside a room-sized computer called EDSAC, one of the first video games ever made woke up: tic-tac-toe. Ex & Oh brings it back as an adventure. SEVEN WORLDS, SEVEN RULES Each world changes one thing about the game you know. • Classic — three in a row, against a machine that learns. • Fifteen — take numbers 1 to 9; three that add to 15 win. • Drop — four columns with gravity. • Wild — place X or O; any line you complete is yours. • Blind — your marks go dark. Play from memory. • Notakto — three boards, only X. Whoever completes the last line loses. • Ultimate — nine boards in one. Your move decides where your opponent plays. A MACHINE THAT HAS SOLVED THE GAME Opponents climb from Novice to EDSAC across ten levels. Where a game is solved, EDSAC plays perfectly — and three stages ask you to beat it anyway, in the variants where the first player can force a win.
