Довольная сложная игра, долго приходится изучать правила, что бы понять как делать правильные ствки и какие тут вероятности. Я вот разобраться так и не смогла, играла просто так на удачу. Нормально в принципе получается.

Интересный видео-слот см необычным раскладом карт, который не сразу можно понять и разобраться. А в остальном можно смело назвать его близким родственником классического блек джека.

Не знаю как остальные, а я привык к классическим играм и все эти нововведения меня не привлекают. Тем более, что приходится запоминать новые правила. А новичкам это вообще трудно будет, что только отпугнет новых игроков.
