How do you play SOS?
- You can play SOS against the computer, or against your friend.
- When it is your turn, check the bottom of the screen to see whether your desired letter is selected among S and O.
- Then, select a square on the screen that you want to place the letter.
- You earn a point for every S-O-S pattern. They can be formed horizontally, vertically or diagonally.
- The game ends when all squares are filled out.
- The party with the most points at the end of the game wins.

You can play the game in three different difficulty levels (easy, normal and hard mode) in single mode.
