Reviews From google play store

Bts is my life..BT21 is my love cooky πŸ’πŸ’πŸ’πŸ’

Love this game

This game sucks. It's totaly based on luck. The tile is totally random. Long wait for the "churros". And it felt like the game definitely try to make you spend real money. Gacha is really expensive but the reward really smalls....

ΰΈͺนุก ΰΉ€ΰΈ₯ΰΉˆΰΈ™ΰΉ€ΰΈžΰΈ₯ΰΈ΄ΰΈ™ΰΈ”ΰΈ΅

I love the game has new stages an exciting game The graphic is also good The stage is very interesting.

Its really fun!!!


Fun games

I cant play the game.. After installed that so take so much time to login

If u want to pass the level u just have to be lucky, it doesnt require skill. all the damn bubbles will be random and ur chances will be out before the bubble that u need come out, its just frustrating, feels like my life's shortening everytime i play, it does shorten my life since i play the same level over n over again till luck comes to me. The slime be gathering in a place and the last one be on mars or smth and to add its still blocked by the boxes when i wasted like 10 chances to remove em

I love the game and its addictiveπŸ˜…

This game is LIT! Kinda similar to Candy Crush but it's like a mixture of all good and popular ganes. Plus, there's the adorable BT21 characters to make it too cute to resist! Amazing game.


Its really good but in our country we don't use line app so I can't login can't we simply just do it with the Google I'd or maybe Twitter cause because of this I can't properly enjoy the gameplay please take in my request and tell me what can I do about it

I'd really like to be able to enjoy this game, but it won't let me. I keep getting the "Can't access service in areas with no connection" message. I definitely have a connection - every other app and game I have works. Unfortunate, really.

Would love it if it was offline! πŸ’œ

Nice i like it


I Love it 😁

The gameplay is really simple to understand and fun. The animations of the characters are adorable and the soundtrack is different for the type of levels you play. The soundtrack/background really boosts the game and gives it a vibrant feel. I really like the game overall and im addicted already! <3
