BugTris (버그트리스) is an unlicensed variant of Tetris published by Game Line. The developer is currently unknown.


The main objective of BugTris is to capture bugs that are hiding inside blocks. The player finds these bugs by clearing lines with blinking blocks, then catching the bugs with a net. Once all the bugs are captured, the game continues to the next level. The game ends after level 30 is completed.

  • The game is frequently found on Game Line multicarts, often as one of the first games on the list.
  • Block Puzzle removes the whole concept of catching bugs, so it just ends up being a Tetris clone.
  • Block Puzzle is found solely on the Littlecom 160 multicart.
  • Unlike BugTris which has numerous original songs, Block Puzzle has only one: a slowed-down Metal Force level tune.
  • The Master System version doesn't appear to have had a single release.
  • BugTris was first seen on a Master System multicart called Dodgeball King 7-in-1. This multicart released in December 1995.
