Turn the classic SOS paper game into a friendly rivalry. Share one phone with friends, connect nearby phones over Wi-Fi or a hotspot, or challenge computers offline. Place your letters, complete SOS lines and compete for the highest score.

SHARE ONE PHONE
Two to six players can take turns on a single phone. Enter each player's name, choose a grid and start playing. No network connection is needed for gameplay.

PLAY ON NEARBY PHONES
Connect two to six phones to the same Wi-Fi network or one phone's hotspot. One player creates a room, and friends join using the host's local address and six-digit room PIN. The host chooses the grid and starts the match.

Nearby multiplayer does not require internet access, but everyone must be on the same local network. Playing from different locations over the internet is not supported.

CHALLENGE COMPUTERS OFFLINE
Play against one, two or three computer opponents without an internet connection. Each computer waits three seconds before making its move, giving you time to follow the action.

CHOOSE YOUR BOARD
Pick from eight grid sizes: 3x3, 5x5, 8x8, 10x10, 12x12, 14x14, 16x16 and 18x18. Larger boards scroll sideways to keep the squares easy to see and tap.

LEARN THE RULES
• Choose S or O, then tap an empty square.
• Complete SOS horizontally, vertically or diagonally to score.
• Complete multiple SOS lines with one move to earn more points.
• Score and take another turn.
• Finish with the highest score when the board is full. Equal scores share the win.

NO ACCOUNT REQUIRED
Choose a nickname and start playing. There is no account registration or sign-in.

BEFORE YOU PLAY NEARBY
Keep SOS open on the host phone. Leaving as host or closing its app process ends the room. Temporary connection interruptions preserve player seats while the host remains active.

Use a trusted, password-protected network and share your room PIN privately. Some public or guest Wi-Fi networks block connections between phones. A six-phone hotspot game requires the host to support five connected devices.

ADVERTISING
The app includes banner advertising. Ads and consent services require internet access, independently of local gameplay. Advertising availability depends on your age-range selection, consent settings and network connection.
