なぜボーナスが与えられるのですか？

You can just play with no guarantee and no bonus.

I guess the competition is too fierce...

그냥 무보증 무보너스로 게임 하면 되는데~~

경쟁이 너무 치열 한가봐요…

Hello,

to answer the question "Why are bonuses given?"

Allow me to quote from our well-crafted free casino course dedicated to the bonuses 😎

"Casino bonuses usually take the form of bonus funds or free spins, which are given to players for one of many reasons, including:

• As a reward for making a casino account

• As a reward for making a deposit

• As a reward for being an active player

• As an incentive to start playing again after a period of inactivity"

Have you ever heard about Casino Guru Academy? 😉

As Radka said, bonuses are usually given for some action
