Yup. By the way, the system is, when you buy 1 and hear nothing, you didn't win. When you buy 1 and hear the refill sound, you've won. Only if you've heard the sound instantly after you've bought it. It's possible that for example, the capsule is on 3, next "refill" on 200 and again on 200. When you buy 10, when it's on 4 for example, you win 3 Desmodusses. For individual capsules for example, never buy 10 at the time. Always go 1 at the time, because you can hear the refill sound.
It's merely a system and the "trick" makes no sense either, because when you buy 10 under 80, you don't always hear a refill. The jackpot (gun) is placed in a random capsule (not confirmed though) thus can be in every capsule. It can be on 200, 150 and even 1. When you buy 10 when the capsule is at 1, you hear a refill and the capsule count is set to 191.
