玩法系统
Uno Free Fall is a tile matching puzzle game. In its Classic mode, cards will fall from the top of the screen and can be dropped into one of eight columns. Like normal Uno, the cards have to be matched by color, number or symbol in groups of three in order to make them disappear to score points. Wild cards can assume any color. Sometimes, a face down card can appear. These cards cannot be matched, but reveal their value once its surrounding cards disappear or if a Draw 2 or Wild Draw 4 card is played, which can lead to combos. There is a ticking "row" meter on the side of the screen, that gradually drains as time passes, but the use of Skip and Reverse cards can either briefly stop or extend the meter. When the meter runs out, a row of face down cards will be added to the play field. Completing the goal will cause the player to level up, allowing for more points to be scored and causing the meter to drain faster. The game ends when a card reaches the top of the screen.
