Ruby "unexpected '\n', expecting =>" error without hashes

June 25, 2023

Here is my code

$wins = 0
$plays = 0
$num = 0
$range = 0
$best = 5
$playAgain = true

class NumGame
    def initialize()
        @totalGuesses = 0
        @i = 5
        @guess = 0
    end
    
    def generate()
        puts "Choose Number Range: 0 - "
        $range=gets
        $num=rand($range)
        puts "Guess a Number from 0 - #$range"
    end

    def guess() {
        until @i == 0
            puts "Guess a Number: "
            @guess = gets
            @totalGuesses=@totalGuesses+1
            @i=@i+1
            if @guess>$range or @guess<0
                puts "Guess out of range"
                next
            end
            if @guess == $num
                puts "Congrats! You guessed the number!"
                $wins=$wins+1
                if @totalGuesses < $best
                    $best=@totalGuesses
                end
                break
            elsif @guess < $num
                puts "Higher - #@i guesses left!"
            else
                puts "Lower - #@i guesses left!"
            end
            if @i == 0
                puts "Sorry! You lost the game!"
            end
        end
        $plays=$plays+1
    end
    
    def replay()
        puts "You've played #$plays games and won #$wins games!"
        puts "Your best game was #$best guesses!"
        puts "Play Again? [y/n]"
        @choice = gets
        if @choice.start_with?("y")
            playAgain=true
        else
            playAgain=false
        end
    end
end

game = NumGame.new
while playAgain == true
    game.generate
    game.guess
    game.replay
end

Error is on the end statement in the guess function. There are no hashes so I don’t understand why there is an error. Other articles don’t have good solutions for this type of program. Any help is greatly appreciated. Thanks.

I’ve tried adding the ==> but that doesn’t work as there are no hashes in the code. I’ve tried using other Stack Overflow articles but none of them work.
