Parts 1. You can see the base and cannon that form the centerpiece of the set. There's also a large coin that may have some applications.
There are a bunch of sloped pieces with studs on the slope face. Also some 1x2 Cheese Slope-like pieces with a slightly different angle than Lego ones. Those 1x1 plates w/Bars and 1x1 Round Plates w/Bars plug into the textured hoses in the picture to the left.
You can make somewhat of a frame from the pieces in this set.
Can you build a frame, frames, or terrain right away? Yes. (+5)
Is it below, at, or above the golden ratio? At the regular price, $11.99, it's above -- $0.16 per piece. (-10) (The Golden Ratio is $0.10 per part.)
If you can't build a frame right away, or choose not to, does it have parts you should be able to put into use right away? Yes. (+5)
Does it have more than a handful of immediately useful parts? No. (-5)
Score: -5 (B-). It's a fun set that has possibilities but get it on Clearance.
