What are the different Uno Flip card symbols and how do they affect gameplay?

Uno Flip cards have two different symbols: a light side and a dark side. The symbols include a draw card, skip card, reverse card, and wild card. The dark side symbols can reverse the direction of play, skip the next player's turn, or make them draw cards. The wild card allows the player to choose the color being played. These symbols add a twist to the gameplay and can change the course of the game.
