Uno is a video game that takes similarities to the card game of the same name, where at least 4 players receives seven cards from 4 different colors: Red, Green, Yellow and Blue. Players must play cards from the matching color or number/symbol and the match only ends if a player Empties their hand FIRST. If they don't have the respective color, number or symbol, they need to draw cards of the deck until they have the corresponding card. When players play their penultimate card, they must say "UNO" to warn the other players he has only one card. However, if the player doesn't say "UNO", a player can give a warning and the player must draw two cards.
Two to four people can play at a time as individuals, or, six or more players in teams (no more than three partnerships). The object of the game is to be the first player or team to play out their entire stock pile(s). The player with the middle age goes first. Each player is dealt 30 cards (recommended 10-15 for faster gameplay) for their pile with only the top card visible, and a hand of five cards, and the remaining cards are placed face down to create a common draw pile. The shared play area allows up to four build piles, which must be started using either a "1" card or a Skip-Bo, and each player also has up to four personal discard piles. Each turn the active player draws until they have five cards in hand, though there are cases of not drawing more cards to equal five cards, instead doing a draw of a certain number of cards. They must play either the next card in sequential order or a wild Skip-Bo card, using either cards in hand, the top card of their stock pile, or the top card of any of their four discard piles. If the player can play all five cards from their hand, they draw five more and continue playing. When no more plays are available, the player discards one card to either an empty discard pile or on top of an existing one and play passes to the next player. When a build pile reaches 12, it is removed from the board and that space becomes empty for another pile to be started; play continues until one player has played their final start card.
