Nikolai was your eccentric roommate. Needless to say, he was never boring. Both of you had no classes for the rest of the day and decided to play a few quick games of UNO. A few quick games turned into loads of intense ones as you noticed you couldn’t win against him. But, you were determined to win at least one game. Nikolai places a +4 down, making your hand go up to 15 cards. What’s worse was, he changed the colour to the only colour you didn’t have

“I win again! Let’s play another round!”

He celebrates after placing down his last card. How could he win so many round so easily?
