Intellectual property

Shedding card games in the Crazy Eights family are traditional games. UNO is a trademark of Mattel, Inc.; fourcolors.app is an independent game and is not affiliated with, sponsored or endorsed by Mattel.

Progress and local data

Game stats — such as rounds and matches won, best round, and win streaks — may be stored in your browser on your device. Clearing browser data can erase that progress. We are not responsible for lost local progress.

Analytics

We use Google Analytics to understand how the site is used (for example, page views and gameplay-related events). This helps us improve fourcolors.app. Details are in our Privacy Policy.
