Pong

Keep the ball in play — if it gets past your paddle, your opponent scores. The ball's angle depends on where it strikes your paddle: the edges send it steep, the center sends it flat, and every hit makes it a little faster. First to the target score wins the match.

Solo: you're the left paddle — W/S, ↑/↓, or drag anywhere on the court. On touch screens, hold the ▲/▼ buttons below the court. Duel: left player uses W/S, right player uses ↑/↓ — or each drags their own half of the court. Space/P pauses.
