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.
