Max Score Bugtris (버그트리스/Beogeuteuliseu) Ending
3Bugtris is a rather unique unlicensed Tetris clone where the player clears lines to free bugs (really alien sprites ripped from the NES version of Galaga) to catch for points and finishing levels. It was made in South Korea in 1987, back when that country still had an illicit reputation for making unlicensed and pirated games for the arcade and other consoles without their respective manufacturers' permission, similar to present China and Taiwan (South Korea did slowly develop a legitimate video game programming reputation that still holds today, though). As shown by Fergzilla23, Bugtris is not endless since the game freezes when you beat Level 30 after the short jingle. Here's the ending if you max the scoreboard. This is the best possible ending and accomplishment in Tetris history.
