It is packaged well in Puzzle Master's usual plastic clamshell and has a card with it telling you that the aim is to remove the ring. This one is really nicely made and unlike the other one I tried, it had no white residue on it - in fact it sings nicely to the magpie in me (I love shiny things!). Dimensions of the main part are 8.9 x 5.7 cm. This one jingles less than the others, which should please the present Mrs S! The difficulty is rated as a mere level 8 (Demanding) out of their scale of 5 to 10. I personally found it much easier than this but others I have given it to have all struggled so maybe it is correct. No solution is given and I don't think that you will need one. But if, like me, you want everything to do with your puzzles then you can download a pdf solution here.
Smuggler's revenge from House of Marbles in the UK. Needless to say, I had already solved it and therefore this one didn't take me very long to redo. Given a choice I personally would pick this version over the HoM one because it is much larger and quite beautifully finished. If you are collecting wire puzzles then this one is definitely a classic and should be in your collection.
So which one should you buy? That depends! This is a classic wire puzzle design and everyone should have at least one version. I definitely prefer the wire versions to the brass one. If you are new to wire puzzles then go for the plain Scorpion. If you are an experienced puzzler then get the Scorpion's Sting OR just get both - you know you will eventually anyway!!! I have both and they are perfect for torturing people with sequentially - they are so happy when they manage the first (easier) one and really upset when an almost identical new one ends up so much more difficult! Mean!! Aren't I?
