Topbrick Updates #3 – Illegal Moves

Alright so last week we got through the Maze, and next week we’ve got another review that took me far too long – Lego Ideas’ Wall-E. Don’t worry from now one when I mention a set in the updates it means the review is already done. It also seems that I’ve found and fixed the issue with the Spectrum charts (an issue of reading too far in the CSV file)

This week though we discuss something that I was informed of reading more about JKBrickworks maze, particularly his comparison from his model to the official model. To borrow from the term of Chess, when it comes to official Lego sets – there are rules on what connections you can and cannot make. Some of which are actually quite common in my remixes (which are often very fragile) done simply to make sure all pieces get used.


You should read through the whole presentation, but what makes the connections illegal or ‘out-of-system’ basically comes down to 2 main rules. Does the connection fully ‘click’, and is this connection putting stress that will warp pieces over time. These stress rules are very deliberate, and in fact some even can be broken by the 0.14mm difference caused by having the words Lego printed on the top of a stud.

Know of any other guidelines considered ‘Out-of-System’ not included in this document? Add a comment and maybe over time we can compile an easy to read list/infographic.

Lego Ideas – Maze (21305) Review


Lego Ideas – Maze (21305): Apologies for the delay getting to this review. I’ve learned my lesson though and promise from her out to never promise a review on a schedule until it’s actually ready to go. Anyway as the mini-review a few weeks on JK Brickworks Ballista proves I am in love with the creations they make. Now though one of them has actually gone through the Lego review process and comes to us in this large set.

What Else? So this is part of what took so long for this review, but instead of just doing a section showing the alternatives in the back, and possibly some GIFs of solving the puzzles – I decided I should make my own puzzle. My main approach was to do one where 2 balls were required forcing you to be vary careful in your movements, and also to showcase the 2 default themes to the maze.



Remix: For my remix I actually took a page out of JK Brickworks book (of a Trebuchet) and turned the maze into a catapult.  Thanks to the large base of the artillery I was able to sneak and hide the remainder of the pieces leaving me up to the addition of a single piece which in this case is a machinists v-block to act as a counter weight. (Which I guess fits the +/- 5 piece rules for remixes?)

Now I will admit that despite the little pull trigger I have and the weight – this doesn’t exactly fire in any spectacular way. It does however look the part.

Final Thoughts: I love this set, and it’s not just because it’s another Ideas set, or because it’s from Jason, or even because it’s like those old ball maze games that I also love. I love this set because it’s totally unique to a lot of what Lego sets you would see in a store, but in truth it embodies what Lego can be. Something that isn’t just basic bricks or technic, but a combination. Something that can easily adaptable from other sets and themes that practically forces it to not just be a display model. It’s something a parent would have just as much fun making and playing as their kid would. There’s been a lot of really complex or ‘neat’ sets that have tried and failed to go through the Lego Ideas process – but I really think they understood here. That they knew a set like this had to be Lego.

Final Score: 5 out of 5 Stars
