Bounty League needs to buy "tickets" to enter this mode. This mode also has access conditions, just like ranking, except that ranking is free, but there are requirements for the number of level heroes, so you can use gold coins to enter this mode.

You can only buy tickets three times a day. The three times mentioned here refers to the number of times you enter this mode, and the number of times you buy a ticket is only three times a day. If you want to play after three times, you have to wait for the next day.
