Undake30 Same Game

A strange, rather obscure Mario game for the SNES, Undake30 Same Game was a puzzle game (released only in Japan) that was probably released around the time of Super Mario World, judging by the Fire Flowers and Yoshi Eggs. The game was controlled with the Famicom Mouse. The game centers around a large playing field composed of a random arrangement of Mario Heads, Coins, Eggs, Fire Flowers, and Super Mushrooms. If two or more icons are connected, you can move the cursor and click to make all the connected icons disappear. Now the icons above fall down and you can clear even more icons. Also, there is an undo move that allows you to take back your last move, and move back as far as you want. Once the entire grid is clear, the game ends. The game was developed by Hudson Soft.

This idea was later re-used in the minigame Pair-a-Gone.
