Word Crack 2 has a 15x15 grid on which you'll have to place the suggested letter tiles to form different words. These words have to be connected to each other by at least one letter.
If you were the player that started the game, the first word will have to be placed so that one of the letters is formed over the center star cell. From this first word, the following words must be formed.
If this is your first game, you will be able to view a brief tutorial, in which you'll be explained how the game works.
On the lower part of the screen, from right to left, you will see different options:
Swap your tiles: you can swap the tiles you want. You can swap them and keep your turn by watching a promotional video, or simply swap your tiles and let the turn go to your opponent.
Pass your turn: you will have to confirm by taping on 'Cancel' or 'Accept'.
Shuffle: you can change the order if your tiles.
Both players will share the same bag of letters. The player who generates the highest score once the bag is empty will be the winner and get 300 coins.
