Revisional Differences

To do:
Extract the music

Two versions of the game are known to exist.

  • The earlier MSX revision, known as L.3.W, published by Screen Software
  • The later MSX revision, known as Super Columns, published by HiCOM and also released for the Sega Master System:


  • Super Columns uses a nearly completely updated font:
L.3.W Super Columns

  • No year is displayed in the title screen. The date shown during gameplay was also shortened to just the year in order to make up for the game's title.
  • The "3" in L.3.W's title graphic flickers red and blue; no such effect is present in Super Columns.

  • There is an additional Tetris game mode in Super Columns.


  • The music is completely different between both versions of the game. Additionally, while L.3.W uses two BGM tracks, Super Columns uses only one.
