I decided to create a "best of 3" scenario (which is often what happens in real life) and before I'd watched the video had finally come up with the following code:
Random random = new Random();
String again = "y";
int computer_rand;
int computer_wins;
int player_wins;
while (again == "y")
{
Console.WriteLine("Welcome to Rock, Paper, Scissors!");
Console.WriteLine("Best of 3 rounds wins!");
Console.ReadLine();
computer_wins = 0;
player_wins = 0;
while (player_wins < 2 && computer_wins < 2)
{
String player = "";
String computer = "";
while (player != "rock" && player != "paper" && player != "scissors")
{
Console.WriteLine("Choose rock, paper or scissors: ");
player = Console.ReadLine();
player = player.ToLower();
}
computer_rand = random.Next(1, 4);
switch (computer_rand)
{
case 1:
computer = "rock";
break;
case 2:
computer = "paper";
break;
default:
computer = "scissors";
break;
}
Console.WriteLine("Computer is " + computer);
if (computer == player)
{
Console.WriteLine("TIE - REMATCH");
Console.ReadLine();
}
else if (computer == "rock")
{
switch (player)
{
case "paper":
Console.WriteLine("You win the round");
player_wins += 1;
Console.WriteLine("You: " + player_wins + " Computer: " + computer_wins);
Console.ReadLine();
break;
case "scissors":
Console.WriteLine("Computer wins the round");
computer_wins += 1;
Console.WriteLine("You: " + player_wins + " Computer: " + computer_wins);
Console.ReadLine();
break;
}
}
else if (computer == "paper")
{
switch (player)
{
case "scissors":
Console.WriteLine("You win the round");
player_wins += 1;
Console.WriteLine("You: " + player_wins + " Computer: " + computer_wins);
Console.ReadLine();
break;
case "rock":
Console.WriteLine("Computer wins the round");
computer_wins += 1;
Console.WriteLine("You: " + player_wins + " Computer: " + computer_wins);
Console.ReadLine();
break;
}
}
else if (computer == "scissors")
{
switch (player)
{
case "rock":
Console.WriteLine("You win the round");
player_wins += 1;
Console.WriteLine("You: " + player_wins + " Computer: " + computer_wins);
Console.ReadLine();
break;
case "paper":
Console.WriteLine("Computer wins the round");
computer_wins += 1;
Console.WriteLine("You: " + player_wins + " Computer: " + computer_wins);
Console.ReadLine();
break;
}
}
}
Console.WriteLine("Your wins: " + player_wins);
Console.WriteLine("Computer wins: " + computer_wins);
if (computer_wins > player_wins)
{
Console.WriteLine("Sorry, you lose. Computer wins the best of three");
}
else
{
Console.WriteLine("Congratulations! You won the best of three!");
}
Console.ReadLine();
Console.WriteLine("Play again? y/n?");
again = Console.ReadLine();
}
Console.WriteLine("Thanks for playing!");
Console.ReadKey();

A shorter version of this code -
namespace ConsoleTesting
{
internal class Program
{
static void Main(string[] args)
{
var random = new Random();
var playAgain = true;
while (playAgain)
{
Console.Write("Enter ROCK, PAPER, or SCISSORS: ");
var player = Console.ReadLine().ToUpper();
while (player != "ROCK" && player != "PAPER" && player != "SCISSORS")
{
Console.Write("Invalid input, enter ROCK, PAPER, or SCISSORS: ");
player = Console.ReadLine().ToUpper();
}
var computer = random.Next(1, 4) switch
{
1 => "ROCK",
2 => "PAPER",
_ => "SCISSORS"
};
Console.WriteLine("Player: " + player);
Console.WriteLine("Computer: " + computer);
var result = player switch
{
"ROCK" when computer == "ROCK" => "It's a draw!",
"ROCK" when computer == "PAPER" => "You lose!",
"ROCK" => "You win!",
"PAPER" when computer == "ROCK" => "You win!",
"PAPER" when computer == "PAPER" => "It's a draw!",
"PAPER" => "You lose!",
"SCISSORS" when computer == "ROCK" => "You lose!",
"SCISSORS" when computer == "PAPER" => "You win!",
_ => "It's a draw!"
};
Console.WriteLine(result);
Console.Write("Would you like to play again (Y/N): ");
playAgain = Console.ReadLine().ToUpper() == "Y";
}
Console.WriteLine("Thanks for playing!");
Console.ReadKey();
}

Thank you! Great logic, and explanation!

[@alexandregb566]

I think your computer was tricking you in this game. I've been following your playlist for weeks, and I've been learning a lot with you. Thanks for making this video.

[@manuelhernandez2017]

Bro, fantastic explanation of logic and clean coding and practice

[@qarnma0h1]

Thank you so much. Very well explained.

[@dijol739]

Dude, Big thanks for explaining it! Now I understand it better.

[@ragnal82]

Amazing explanation BRO. Thx again for your input.

[@Aahegaaooo]

Thank you so much! Finally some good explanation, comparing to my teachers)

[@guillermodanielmazzarigiov1768]

Nice one bro!!! Thanks for sharing, learned a lot with this video!!

That's kinda random

shortcut for random number:

all that code for such a simple little program.
what the hell did i get myself in to...

It's simple to understand so it's balanced I'd say

I took the final result and added a score system of first to 3. Whichever wins (player or computer) it displays they won and the score after each win.
using System;

player = "";
computer = "";
answer = "";

while (player != "ROCK" && player != "PAPER" && player != "SCISSORS")
{
Console.WriteLine("Enter ROCK, PAPER, or SCISSORS: ");
player = Console.ReadLine();
player = player.ToUpper();
}
switch (random.Next(1, 4))
{
case 1:
computer = "ROCK";
break;

Console.WriteLine("Player: " + player);
Console.WriteLine("Computer: " + computer);

if (computer == "ROCK")
{
Console.WriteLine("It's a draw!");
}
else if (computer == "PAPER")

Console.WriteLine("You lose!");

[@manuelhernandez2017]

Accumulation of score/wins throughout several runs? Suggestions?

[@CorneliusCorndogJr]

add some variables that go up for both the computer and player and add them into the if else statements ex:
if(computer == player){
System.Console.WriteLine("DRAW");
playerScore++;
computerScore++;
}

Hi! I'm a beginer, why you use String? I'm use string and the program worcs.

String is basically text

How do I put it to three rounds instead of 1 round, please help ASAP.
