Ono Classic Cards is a simple and fun card game with rules similar to the classic card game "UNO". Players need to hold a set of cards with different colors and numbers in their hands, and then win the game by playing the cards. The gameplay is simple and easy to understand, but requires clever strategies.

Game players need to play cards in their own turn and match the cards played by the previous player. This means that the cards played are either the same color as the previous card or have the same number as the previous card. If the player does not have any cards to play, they must draw one card from the deck. If the card touched can be played, it must be played in this turn.

There are also some special cards in the game, such as skipping turns, changing the game order, strengthening or weakening the cards of other players, etc. These special cards can help players win, increasing the challenge and fun of the game.
