Surrendering my Jurassic Park rental today, and I took a few shots with the glass off while I was cleaning and tightening before I did. High score is glass-off btw,. The rules are complex, and even good players become obsessed with having to hit a shot that differs from those they're most comfortable with constantly for some ridiculous multiplier. It gets challenging, but it stays very fast paced and fun as a result. Buying a brilliant game that costs about as much as a new floor for most of the house or a decent used car just will never happen.
