...my true love gave to me three Christmas games:
See how far you can get the Yeti to bop the penguin.
A cutie with music: the higher the bunny hops onto the bells, the more points you get.
This one's neat: you draw a slope from left to right, click "play," and a little man slides down the slope you have made. The smoother the line the better; if you draw the curves just right you can get him to loop-the-loop without falling off the sled.
