Всем привет! Прошу намекнуть на ошибку, а не отправлять готовое решение :)
У меня не проходят два требования: третье и пятое.
1) Не понимаю, почему не проходит третье требование. В методе createGame() я первым делом проверяю, остановлена ли игра, и если да, то присваиваю матрице новую ссылку на пустой массив:
