Uno

UNO is a highly entertaining multiplayer board game for all ages. Which game was created by an American teacher?
Number of players: from 2 to 10 players.
Rule:
One person shuffles the cards carefully and deals seven cards to each person. After dividing, the remaining portion is placed in the middle. You turn over one card in that pile and place it face-up next to it to create a discard pile. We choose the first person to start and then go clockwise.
During your turn, you can play a card with the same number, color, or symbols as the top face-up card in the discard pile. For example, if the face-up card at the top of the pile is a yellow 7, you can play a 7 of any color or a yellow card.
If there are no cards that can go, the player will have to draw one card from the face-up pile.
When you have one card left in your hand, you will have to shout, "UNO". If you do this and other players discover it, you will have to immediately draw two cards.
Expanded version: Besides the pure version, Board Game UNO also has many other variations, such as: UNO expansion #1 (UNO Battle), original UNO Mattel,...
There are also some interesting board games for two players, such as connect 4, Cross-Attack, etc.
