It can be done, but you need to be able to handle the packages. Different minifigure series may require different approaches, from barcodes to patterns of dots or dimples to feeling for certain characteristic parts in the bags. Those approaches have been documented in a number of places:
Series 6 (feel + dots)
Series 5 (feel)
Series 4 (bumps)
Series 3 (...
LEGO will replace a part for free on their website, providing it was missing from purchase. Sadly replacement parts aren't available for Collectible Minifigures, but you can contact them to let them know.
Ensure the Minifigure packet has been fully emptied, it's quite easy to lose parts when you open the packet.
In short, yes it is possible.
The best place to find replacement parts is Bricklink.com.
You don't mention which minifgure is missing its leg, but for example, here is a link to the 'Hips and Legs with Studded Belt and Safety Pins Pattern' of the Series 4 minifg 'Punk Rocker'.
To find the required part for your minifig, a good starting point would be to ...
You should be able to find this piece by looking up any of the collectible minifigures on Bricklink and looking at the set inventory.
This piece is the Tile, Modified 3 x 4 with 4 Studs in Center (88646).
It is classified on Bricklink under the category 'Tile, Modified'.
I managed to get the five minifigures I wanted, right every time by feeling the bags. It takes patience and a good understanding of how different bricks feel. There are some guides online that show you which individual pieces to look for.
Use the process of elimination. If you're looking for the Witch minifig, look for a bag with slope instead of legs. The ...
That sounds like a very valid question, but I think the answer is slightly more complex.
First, as you note, there's an obvious link in terms of moulds reuse, which means LEGO can offload the cost of these new parts to the minifig series (which aren't exactly on the cheap side), so that regular sets introduced later can be cheaper as a result. They do that ...
I know the question was phrased as a sort of math problem, but most LEGO fans solve it as a sort of LEGO problem. The bags are opaque, so you cannot see what's in the bags, but almost everywhere they are sold you can feel the bags, and you can determine what figure is in the bag. With the exception of the recent Soccer Team figures, collectible ...
I was really stumped on this when I posted the question because there didn't seem to be any place to attach to. But then I realized the neck could be a starting place. I tried some things with hinges and plates, but decided to simplify and I ended up with:
With only 4 pieces I was able to get this to work out pretty nicely. From neck to plate there are:
For any CMF's with skates, I put the figure on the stand with no footwear, and attach the footwear to the holes behind their legs. That way their accessories are there, and stuck to the figure, but the figure is on its stand!
It's known as the "Coupon collector's problem". To get all 12 you would on average need to buy 38. Buying a whole box (or finding someone who did and buying a set from them) seems like a much more attractive solution.
If the distribution is assumed to be completely random (not necessarily true), and of a large enough group to make your purchases not effect the total probability (likely) then this is an alternate of a classic math problem known as the Coupon Collector's Problem:
There are many ...
Another option to help finish off your collections is BrickLink, sort of the eBay of LEGO. There are plenty of sellers in the US with a large amount of reputation
Here is a link to BrickLink with a listing of the Collectible Minifigs:
Be sure to buy the 'complete set' figs otherwise you will probably not ...
My boys and I purchased a precision scale for nine dollars from Harbor Freight and set it to grams. We purchased ten Lego minifigures series nine. We measured the ten empty packages for a weight of 19.8333 grams and divided by 10 to get an average wieght of 1.983 grams, or rounded to 2 grams. We then weighed the ten inserts showing the 16 numbered, named and ...
Some of the minifig parts that are officially made in China (often including the Collectable Minifigures) don't have the copyright/logo stamp on the inside toe - I noted that in a comment to my answer on What does the imprinted information inside bricks mean?
Every box contains the same distribtion of minifigs. For example see this review on www.eurobricks.com of series 13 has the same distribution as my box. (links to his other CMF reviews are on the bottom of the first post)
For most series boxes contains 3 full sets and 12 remaining ones.
Series 9, 10 & 11 contain only 2 complete sets, with 2, 4 or 6 ...
If you are on good terms with your lego store, you could buy an unopened box with 60 bags which will guarantee you to have 5 of each. You shouldn't have much difficulty selling the other series, even if the bags are opened, to get your money back.
Spring-boarding off your nice work-around, I would suggest a further aesthetic tweak with the symmetrical re-positioning of the support shaft, and as a bonus, eliminating the 88646 tile all together, if it's not being used.
I don't have penguin accessories in my parts library, but here are some pics to help visualize my techno babble;)
While looking up ...
On thebrickblogger.com (February 9, 2017) there was a call to report issues with minifigures. Reading the answers I get the impression that issues with clutch-power, cracks and other problems are occurring with all sorts of minifigures, not only with the collectible series. This would mean that it is not a persistent problem with Chinese factories:
I don't think that such a set exist. The most complete database are the ones indicated by Guilherme Branco Stracini, BrickLink and BrickSet, but both of them tell in their footer that the content is copyrighter so I am not sure that, especially if you intend to sell your app, any of them will allow you to use their content.
On the other hand, BrickLink ...
It depends on licensing as well. Note that they have made sets for Ultimate Spiderman. The X-Men designs all follow their comic counterparts. Loki, Thor etc follow their Movie style counterparts.
This suggests that they have the license for the comic and animated styles, but Fox and Sony retain the rights for the movie looks of the characters.
i find it rather easy to feel for the minifigures. All you have to do, is identify a uncommon trait that only that minifigure has, and then feel for that. for example, the conquistador has a breastplate. just feel for something bendy, hollow on 2 sides. its not that hard.
