To send a game request to another user, you must click on the "Play" button that you will see on your home screen; by doing so, you will be able to select the game mode you want and, if you choose "Mountain Track" or "Toad Kingdom", you will be redirected to a new screen from which you can:
- Select a random opponent: you will find the option "Random" to the right of "Invite friends".
- Play with your Facebook friends: keep in mind that by clicking on this option, at the bottom of the screen, your game account will be linked to your Facebook profile. In doing so, you will be able to view the list of friends who currently have the application on their devices. By clicking on their profile photo you will be starting a new game with them.
- Invite friends: you can use this option to invite friends who are not yet in the game. To do this, click on the green icon that you will find on the left side of the screen. Once you do, different social applications will be displayed through which you can invite your friend to the game. When your friend receives and accepts the invitation, they will appear as a friend available to play every time you want to start a new game. If you want to invite another friend, you will have to follow these steps again.
