Each game has a board where you can place tiles and form new words.
The first word of the game should be placed so that one of its letters is found on the center square (marked with a star). The second word must be connected to the first one and all subsequent words must have at least one letter in common with at least one of the words that were played before.
If you can’t form a word with the letters you have on your rack, you can pass or swap your tiles by tapping on the corresponding button at the bottom of the screen. Both actions will end your turn.
