Cero is a remake of the most well known game Uno, with a few different twists and adjustments that can be made. These twists include preventing someone from ending with a Wild or Wild+4, making sure everyone can see how many cards you have left without peeking at what you actually have, and adjust the amount of cards you start off with. There's some variations to the cards, but they aren't as noteworthy from your standard Uno game. Just be sure to give it your all when you play.
