Грешно си интерпретирала инструкциите. Този метод се използва за да видим какви ирачи имаш, а не за да ги инициализираш. Играчите трябва да се инициализират още при инициализиране на класа. Този метод просто ни ги показва, но и без него трябва да можеш да работиш с класа.

Тук не си имплементирала събирането на карти от играчите. Виждам, че по-долу се дефинирала ново тесте при конкретните игри, което до известна степен се справя с проблема, но идеологически погледнато, ако седнеш да играеш карти, не вадиш ново тесте на всяко раздаване.

Като цяло доста добър стил на решението ти. Добра идея да използваш опашка. Явно обаче си прибързала решението, защото имаше коментари по интерпретацията. Не оставяй нещата за последния момент.
