How to play

• Solo: pick your side (UP or DN), pick a difficulty, play against the AI.
• Online: tap ONLINE, share your 4-digit room code with a friend, or enter theirs. Match starts when both players connect.
• Controls: tap to rotate. Swipe left/right to move. Swipe up or down to hard-drop.
• Winning: clear rows to push the boundary into your opponent's territory. Squeeze them to zero rows to win.

Troubleshooting

• Can't connect online: make sure both players are on the same room code and have an internet connection. If your friend already entered a code, the room may be full - start a new one.
• No sound: check the iPhone silent switch on the side of your phone. Also confirm Sound Fx is on in Settings.
• Match froze: if your opponent disconnects mid-game, you'll see a message and can return to the menu.
