UNO is a mobile card game featuring classical card game mechanics. Though you might already know how to play UNO, we still want to provide you with some tips so that you could play the game more strategically and have a higher chance to win. First of all, at the beginning of the game, you should count the number of your cards. In this way, you could be able to be aware of the used cards. To do so, you should pay attention to the cards you have. Secondly, cards with matched numbers are no good. You should use them up as early as possible during the gameplay process. Thirdly, though we recommend you to get rid of the matched cards as quickly as possible, when it comes to the case of the wild card, you should keep it till the end of the game. Fourthly, be cautious when using the card with reverse numbers because using it at the wrong timing might lead to your final loss. Fifthly, if you have several cards in similar colors, you should play them first so that you could have lesser cards quickly. In addition, you should make sure that there is always a +2 card. If you use it up too quickly, it will set limitations on the way how you can play the game. Furthermore, throughout the game, you should use the cards with higher numbers in first place. It not only saves you time to decide which card to use first but also decreases the opponents’ chance of winning. Last but not the least, you should observe the actions taken by your opponents closely because what they do might suggest what kinds of cards they currently have. We hope our tips could be helpful to you. Good luck!
