BTOOOM! That's the sound a bomb makes apparently and that also happens to be what this anime is about. Ryouta Sakamoto is one of the top players in the world at an online game called "Btooom." In this game, players fight against one another using nothing but different types of bombs. One day Ryouta finds himself waking up on a remote island completely uninhabited by other people, or so he thought.
Ryouta soon finds out that he has been placed on an island with several other people and the only way for them to leave is to kill seven other people and take their chips. So think Hunger Games or Mirai Nikki, but with bombs instead of Future Diaries.
Despite Btooom being yet another Battle Royale ripoff, it manages to entertain plenty. It has a darker animation style than most other anime out nowadays and has an overall feel that's slightly reminiscent of Death Note. It also has an opening theme that's catchy as hell. None of the other music is very memorable though.
I don't have too much else to say about this anime. I really liked it, and if you like anime like Mirai Nikki or Death Note chances are you'll probably enjoy it as well. I give Btooom! a 9/10.
