Thanks for playing and comments! Yes, some rooms were specifically designed to be very "unfair". A room like “1 out of 10” may not appear at all. The chance of getting such a room is very small. (For example, the chance of getting into a room "50% chance" is 4 in 1, compared to a room "1 in 10"). The game also has a "Potion of Luck" that allows you to win in a room that depends on chance. 10 rooms is very little, maybe you are just unlucky. Sometimes I also lost in the first 5 rooms. But it was so nice when I won the first 2-3)
