재미는 그저 그런데

재미는 그냥저냥이긴한데 처음 조합하는 재료중에 합금이란 재료가 지금 200번째 돌리는데 절대 안나옴
전설 조합하려면 합금없으면 전설 딱 1개밖에 조합 못하는데 내가 운이없는건지 합금 안나오는 버그인건지

Response from developer

안녕하세요! 플레이해주셔서 감사합니다. 합금 드랍률 말씀드리겠습니다. 슬롯 심볼 1칸 기준으로 약 2.3%, 한 번 스핀(3칸)에서 합금이 1개 이상 나올 확률은 약 6.8% 입니다. 평균적으로 15스핀에 1개 정도 보이는 빈도예요. 200번 동안 한 번도 안 나오는 건 통계적으로 거의 일어나지 않는 케이스(약40만분의 1)라서 버그는 아니지만, 합금이 전설 조합 6개 중 5개에 들어가서 체감상 답답하셨을 것 같아요. 다음 패치에서 로비에 드랍 확률표를 공개해서 어떤 재료가 얼마나 나오는지 미리 보실 수 있게 추가하겠습니다. 합금 빈도 자체도 유저분들 데이터 더 모이면 조정 검토하겠습니다. 좋은 피드백 정말 감사합니다!
