Oh No! is a card game similar to Uno. The game is very easy to learn and play. There isn't much strategy and it's mostly luck which although can be enjoyable, gives the app a low score in gameplay. The object of Oh No is to discard all the cards in your hand (rules vary based on the few game types available in the app). You'll face three computer opponents. Along the way they're some special cards that have interesting effects on the game to make it more enjoyable. Unfortunately, you're pretty much just tapping on a card from a selection of cards that are playable that round. Although bleak, it is somewhat enjoyable and is a great time killer.
