Zuma Deluxe is a popular color matching game for the PC. In it, you control a frog that spits colored marbles into a long train that proceeds endlessly toward a hole in the middle of the screen. If you match enough colors in a row, a group of marbles disappears. If the marbles go into the hole, you lose the game. Zuma Deluxe is a commercial product, but you can download and install a time-limited trial version of the game for free.
