Overview
Tetris (D.R. Korea) is a rare, bootleg arcade version of Tetris developed by a South Korean company called Uttum Soft (으뜸소프트) and released in 1989. Despite the "D.R. Korea" branding on the boot screen—which stands for the Democratic People's Republic of Korea (North Korea)—the game actually originated in South Korea.
The game borrows heavily from Atari's famous arcade version of Tetris but alters several core scoring and progression features:
• Line-Based Progression: Points do not dictate your score. Instead, the game tracks the total number of lines cleared.
• Speed Cycles: Every time you clear 40 lines, the board completely wipes itself clean, and the falling speed increases for the next round.
• Cooperative Play: It includes a simultaneous two-player mode, but it is non-competitive; both players focus on clearing lines on their respective sides without directly sabotaging each other.
