    When faced with a wall of errors and no hope to fix them, remember the following "Programs always do what you tell them to, and seldom what you want them to, but eventually you'll run out of things that can go wrong and it'll just work. and that's the secret to good programming."

Ok i made a rock paper and scissors game i got the game to work but i need to keep track of win,losses and ties and print them im using a hash to do this my big problem is if statement to track the wins,loss.ties
i also used elsif just cant think of what to put to keep track so any help or advice you can give would be appreciated

puts "Would you like to play a game of Rock, Paper, Scissors?"
puts "Y/N"
player_input = gets.chomp.downcase
while true  #loops forever till quit is typed
if player_input == 'y'
  puts "Lets Play Rock, Paper, Scissors!"
  puts "Press r for Rock"
  puts "Press s for Scissors"
  puts "Press p for Paper"
  puts "Press Enter when you select r,s,p"
  puts "Oh if you want to quit at any time just type quit"
  computer = "rsp"[rand(3)].chr
  player = gets.chomp.downcase

case [player, computer]
  when ['p','r'], ['s','p'], ['r','s']
  puts "You Win! Congrats"
  when ['r','r'], ['s','s'], ['p','p']
  puts "You Tied! Bummer, like they say its just like kissing your sister"
  puts "You Lose! Suck It Chump "
puts "The computer chose: #{computer.upcase}"
    tracking = {
		 :wins => 0,
		 :loss => 0,
		 :ties => 0,
	    tracking[:wins] += 1
		  tracking[:loss] += 1
	    tracking[:ties] +=1

else player_input == "n"
  puts "Oh you don't want to lose do you, CHICKEN"
  puts tracking[:wins]
  puts tracking[:loss]
  puts tracking[:ties]
break if player == "quit"

Simplest solution: just declare 3 global variables: wins, losses, and ties, and initialize them all to zero at the start of the program. Increment the appropriate variable by one in your win/loss/tie checking logic.
