If you missed Peggle the first time around, PopCap just released Peggle Nights, which turns out to be more of an expansion of sorts more than a sequel, but retains the same ultra-addictive,"just one more game"quality of the original.In case you've never played or heard of Peggle, here's the rundown: It's a kind of super-powered pachinko. Think Plinko from The Price is Right. The game is broken into different stages, each of which has a different pattern of pegs colored orange, blue, pink, and green. Your job is to fire a ball from the top of the screen and attempt to amass as many points as possible by hitting the pegs. After each ball eventually bounces to the screen's bottom, the tagged pegs disappear. Once all the orange pegs in a stage have been hit and cleared, you move onto the next stage."
