```ruby
require './core/tetrimino'

class Player
    def initialize(game)
        @score = 0
        @linesCleared = 0
        @combo = 0
        @game = game
        @board = Board.new
    end

    # Increments the score of the player relative to the number of lines he just cleared and his current combo
    def increment_score(lines)
        @combo += 1
        @linesCleared += lines
        @score += 100 * 2 ** (lines - 1) * combo
    end

    def reset_combo
        @combo = 0
    end
end
```

Add check to prevent incrementing score with no line
user
```ruby
require './core/tetrimino'

class Player
    def initialize(game)
        @score = 0
        @linesCleared = 0
        @combo = 0
        @game = game
        @board = Board.new
    end

    # Increments the score of the player relative to the number of lines he just cleared and his current combo
    def increment_score(lines)
        if lines != 0
            @combo += 1
            @linesCleared += lines
            @score += 100 * 2 ** (lines - 1) * combo
        end
    end

    def reset_combo
        @combo = 0
    end
