I want to create a simple game on UNITY $2$d that implements the following idea:

The game consists of cards divided on the screen. Each card gives different points, for example from $1$ to $10.$ The game is played by two players. The first player begins by choosing a random card. The card turns over and a number appears containing the card$$s power. This power goes as points to the player. Now comes the second player$$s turn. In the same way, after the first and second player played the first round, now the second round begins in the same way, but suppose that the first player chose a card and its strength or number was $5.$ Then the second player chose and the number $7$ appeared to him. The highest card is counted for the player who chose it and the lowest card is not counted for the player who chose it$.$ Choose it and so on until the cards run out. Of course, I don't want anything professional, just the basics and I will talk about the rest
