Uno Online is for 4-color deck enthusiasts. Especially, this game can be played with up to 4 players on the same device or played online with other players.
You have two main rules for playing cards. First, your card must be the same color as the previous card. Second, your card has the same number as the previous card. Just meet one of these two requirements, and you can play your card. If you do not have any cards that meet the criteria, you are allowed to draw a new card. If this continues, you lose your turn.
However, there are a few exceptions. It can be played in any situation regardless of colors and numbers. Two prominent examples are the +4 card and the color-changing card.
Uno Online is divided into two main types of cards: normal cards and function cards.
The normal cards have 4 colors: blue, green, red, and yellow. Each color will have 9 cards from number 1 to number 9. These cards require you to meet one of the two rules above to be moved.
All Uno Online's function cards are +2 card, +4 card, reversed card, ban card, and change-color card.
