### "Go Live" Checklist
Ready to go live with your Scratch and Win? We recommend reviewing the following list before launching and double-checking if you have:
* All images uploaded to each screen are the **correct dimensions**. Export image files in 2x to ensure none of the images appear pixelated.
* Hyperlinked your [**T\&Cs**](/getting-started/resources/terms-conditions) to the opt-in-field, which is created in the **data capture** section of the settings tab.
* All your **communications** (Prize/s screen and Failure screen) are fully set up and ready to send.
* If you are using **coupons**, make sure the coupons created are set up correctly. Check the coupon limits are set, the copy for each screen is right and you have linked the appropriate coupons to your communications.
* Ensure you have set the **probability** for each result screen.
* Edit the **Styling** of the game to your branding.
* If you have multiple prize screens, ensure to give each an **internal name** to help you distinguish between the prizes in the analytics.
Then you're ready to go live!

## FAQ
**How many prizes can I have?**
You can have as many prizes as you like. The only exception is that the probability of winning all prizes combined must not be greater than 100.
## Top tips
* Set the scratch percentage between 20%-40%. If it is set too high this means your audience will need to scratch most of the image in order for the game to end, they will see the result but may need to continue scratching for the game to end...
* Set the probability of seeing a result screen accordingly. If you have a couple of prizes to give away, set the probability lower so you don't reach your prize limit too soon and drive more traffic to your Hub. If your game is active for a certain period of time, set the probability a bit higher to reach your prize limit.
* Include a bit of information in your cover image. Mention what prize/s can be won. This will get users to engage more as they know the prize/s. You can add this information on the top of the card instead by using the **Options** button located at the bottom of the card and selecting **Description**.
* Set up communications for prize winners in the Result screen section. After designing the Prize Result screen, on the left, you can set up SMS or Email communications. These communications will be sent out instantly when a user has won.
* The communications tab in the Data capture section is an overview of all communications set up for the game.
* Direct users back to the Hub in the Failure screen to compete in more competitions and games. Drive more traffic and engagement to your Hub.
* Creating a 'three-in-a-row' type of scratch game. You can create a screen where users need to find 3 of X items in a row to win to make it more interesting!
