3 Square

Released in 1993 for the MSX2, *3 Square* is a challenging puzzle title developed by Emphasys that tests the player's capacity for logical deduction. The core objective is to clear the board of all crystals by aligning them in sets of three, either horizontally or vertically. Adding a layer of complexity, clicking a crystal triggers a unique transformation where the target piece shifts two positions in the shape sequence, while adjacent pieces shift only once. This innovative mechanic demands careful planning and foresight, standing as a compelling example of the thoughtful puzzle design prevalent in the European MSX home computing scene of the early 1990s.

In this puzzle game, the player's objective is to clear all crystals from the board by aligning three identical shapes either horizontally or vertically. A unique challenge arises from the game's mechanics, where clicking a specific crystal causes it to transform through two stages, while adjacent crystals also undergo a single stage of transformation. Success requires deep logical thought and the ability to anticipate how these chained transformations will affect the entire board. Players must carefully unravel these interlinked changes to successfully remove every crystal and clear each level.
