COLUMNS for HP Prime (WIP)

[Han]

Does anyone happen to know the scoring rules for the game Columns originally created for the Sega Game Gear (or was there an older version)? I've been working on a version for the HP Prime (partly inspired by the HP48 version by Spartacus and Fatri). All that's left for a playable version is the scoring system and the removal of blocks. If anyone has played this game (or perhaps more importantly is old enough to have even heard of this game that was released back in the day), please share what you know about the scoring system.

Edit: well, I went ahead and made my own scoring system. Beta version available from the HP Prime Software Library
