Redd Arremer's video: PS1 KuruKuru Twinkle: Onegai Ohoshisama - stacking matching puzzle

A pretty good puzzle game that never left Japanese shores. You flip colored gems in groups of two by pressing 'Circle' and 'Cross'. Aligning three gems of the same color erases them. To remove concrete blocks you need to connect six of them in a straight horizontal column which will roll down the screen crushing all other gems in its way. 'Triangle' button activates 'Magic'(of which there are several types) - an emergency special move that clears the screen of garbage blocks. Pressing left and right on the d-pad while holding down 'L1' button shakes the screen - a useful move to make piled up gems collapse. 'R1' and 'R2' make more gems fall down from the top of the screen.
