Two players share one phone. Lay it flat on the table between you, one at each end. A ball bounces up and down the court and you each control the paddle at your end — slide a finger left and right along your half of the screen to move it. Bat the ball back; if it goes past your paddle, the other player scores. First to the target score wins.
It's a pass-the-phone, no-signal game of table tennis — sometimes called ping pong or Pong. There's nothing to install and no account. Where the ball hits your paddle changes the angle it comes off, and every rally the ball gets a little faster, so long rallies get tense.
How many players? Two, on the same phone at the same time. It reads both of your fingers at once.
What are the controls? Just touch — drag your finger left and right on your half of the screen to move your paddle. No buttons.
How long is a game? Choose first to 5, 7 or 11 before you start.
Does it need signal? No. Once the page has loaded once, it works fully offline.
