Free online air hockey
CREASE online is a live, first-to-7 air hockey match against another person, in your browser. Tap QUICK MATCH and you are paired with whoever else is looking for a game. To play a friend, tap CREATE A ROOM and send them the invite link or the room code.
You always play from the bottom of your screen: drag your paddle on your half of the table. The server runs the puck, the score and the paddle limits, so a player can't move a paddle where the rules don't allow or invent a goal. No download, no account, no payment.
Want to play the CPU, or two people on one phone? Play CREASE. It was made for the iPhone Duo: open it for two players, one on each side; close it for you vs the CPU.
