However, even expert of playing UNO is not always the winner of the game. Unlike chess, technique is not the most important factor of winning, but luck. UNO always not only play between two players but 4,5 or more. It is nearly impossible to guess exactly what cards are holding by your opponents. It is also hardly to guess what card the player before you will play. As technique is not most important, it is the interesting point of UNO. Nobody will be the winner of the game all the time. Because of this, no one would like to put effort on become expert of UNO, as I mentioned before, without luck, even expert cannot win the game.
