“Puzzle Star BT21” is a charming cross between “Candy Crush” and “Tetris.” With its cutesy concept and must-achieve goals, it’s easy to play for hours.

The adorable BT21 Line characters: Koya, RJ, Shooky, Mang, Chimmy, TaTa, Cooky and Van guide you as you make your way through puzzles that get progressively harder.

The point of the game is to use blocks and shapes given to you to clear rows or lines as they’re called in the game.

Every move matters and you have to achieve your goal to clear the level. Running out of room leads to a failed level.

The game was released on April 2 and has captivated millions around the world.

The characters are representations of the members of BTS, the Kpop group under BigHit Entertainment, with Van representing their fanbase known as ARMY.

The game was a little frustrating to figure out at first, especially if you rush. I had to take a break that lasted a few days because I rushed through the tutorial and couldn’t figure anything out.

The game is free to download on Google Play or the App Store and includes in-app purchases. It requires a bit of patience but it’s completely worth it in the end.

“Puzzle Star BT21” has a cutesy vibe and is easily as addicting as Candy Crush. It’s just the right amount of mindless fun and strategic placing worth all the time in the world.
