Kokontouzai Eto Monogatari (Japan, prototype?) — About this game
Kokontouzai Eto Monogatari (Japan, prototype?) is an exact registered version in this game family. Kokontouzai Eto Monogatari uses three-piece matching rather than a complete line across the field. Three identical items can be arranged horizontally, vertically or around a right-angle corner, and the corner can face any of four directions. Separate left and right rotation actions help place the falling arrangement. Look for a corner already waiting for its third item before committing another piece to a straight column. The accepted shape matters when a field that looks almost full still has a useful match available. Version-specific changes to characters, stages, timing, difficulty, balance, graphics or hidden content are not inferred where the registration does not document them.
