Yosumin!

Yosumin is a puzzle video game for the Nintendo DS console. Developed and published in Japan by Square Enix on November 8, 2007, it is an enhanced port of the original Yosumin browser game released by Square Enix on the @nifty network.

This game is all about making rectangles of the same type of yosumin.
First, let's find a rectangle which has the same type of yosumin at each corner. Once you've found one, select the corners to make it disappear.
To clear the stage, all you have to do is meet the conditions listed under "Target" on the left-hand side! But if the time bar on the right - hand side reaches zero, it's game over, so be careful!
Every five stages in Yosumin! Adventure mode, fragment pieces will appear. If you make all the pieces disappear, you'll get a stained glass fragment. Who knows what might happen when you've collected all the pieces...
