Wow, that was amazing! You found the right combination. This is what is inside: Basket of Yarn Ball Bombs Set of Safe Keys and 30,390 sP
Winning this game isn't happening too often. Yet, for years I have no longer received the book, which used to be a staple and has now become fairly pricy due to be missing from the item pool. (While the keys have become worthless.)
Altogether the prizes are ridiculously measly - the safe owner must have suffered bankruptcy. I wouldn't bet my life on ist, because it is aaaages that I last got a worthwhile content, but I strongly believe the pecuniary prize used to be 6 and 7 digits....
