This week, I have another fantastic burr puzzle created by Eric Fuller and designed by Alfons Eyckmans. This one is called Two Face 3 and is one special puzzle – I’m still reeling from having just completed it.
To begin with, this puzzle is a beautiful work of art. Its visual appearance is stunning – the construction is superb and the choice of woods really elevates the whole design. It’s a 6 piece burr, but unique in that there are two outer cages that can move independently of each other. The inner cage has a few strategically placed cubes and cutouts that combine to make this not only a difficult puzzle, but also a very clever one. The construction of the cages is incredibly sturdy and they fit together very tightly making for a very solid feeling puzzle.
The overall design is very clever. The use of two cages is not just for looks either, it factors into the solution.
This was another intimidating puzzle for me. It sat on the shelf for a couple of weeks before I started to tinker with it, and then it was another week until I really decided to put some effort into it. Whether it’s intimidation or a desire to relish the puzzle as long as possible, I find that sometimes, I’m just content to let it sit. Maybe I don’t want the experience to be over, so I procrastinate a bit, I let the puzzle breath like a fine wine, until that perfect moment arrives and then I sit down with a job to do.
And so, I finally sat down with this one last week and began to seriously work on it. I began exploring different moves and discovered some typical burr-type moves, but didn’t make any real progress. I kept going in circles, with no real progress made.
I spent a number of sessions doing this. Moving pieces, feeling like progress was made only to find myself back at the beginning. Early sessions like this are enjoyable to me – I don’t really want to solve it quickly, I just want to enjoy the experience for a while and Two Face 3 really delivered the goods. But, that said, after a certain number of sessions, i start to feel like I need to make some more progress – so, I increase my focus and start trying abnormal moves.
This yielded some success for me as I discovered an interesting placement for one of the pieces. Surely I was on to something here! But, even with this new discovery, I couldn’t make any progress. I was able to revert back to the beginning position and then repeat the move, but it still didn’t yield any solution.
After a few more sessions, I discovered a similar move at another location and then knew I was making progress. But, to my dismay, the solution still wasn’t there. Man, this puzzle really takes some work! I spent another day working various moves but couldn’t make progress. I had to be on the right track didn’t I?
Well, one morning, I took the half-solved puzzle to work with me and sat there fiddling with the pieces when suddenly, one fell out! Holy crap! I didn’t expect that, but apparently I had done the right thing and was rewarded. I spent the next 15 minutes carefully removing the remaining pieces and then bathed in glory as I examined all the pieces and marveled at the craftsmanship.
Then, fear set in. I went from joyful elation to fear. I was so happy to have solved the puzzle that I forgot to pay attention to the orientation and position of the 2 cages and the burr pieces. I didn’t really think about the fact that the 2 cages could be put together in 8 different ways… and if they weren’t put together correctly, then there’s no way the burr pieces would fit… How on earth was I going to get this thing back together…?
Well, the good news was I had taken various photos while tinkering with the puzzle. So, I went back and took a look at those photos and was able to deduce the orientation and placement of the 2 cages – phew – crisis averted. Although, that would have made one heck of a challenge – to start with this puzzle completely disassembled and go from there. Maybe one day..
Anyway, even though I had the orientation of the cages documented, I still didn’t know how to reassemble this thing. I did keep track of the order in which I removed the burr pieces, and that would prove helpful, but it wouldn’t move the puzzle for me.
In the end it took me at least another 3 hours to put it back together. It’s a tricky puzzle and requires a very specific sequence to solve it. Interestingly, I employed a rotation to put it back together – I’m not convinced that it was entirely necessary, but at a certain point, rotating the burr piece allowed another piece to move where I wanted it and then I rotated the original piece back. Again, not sure if it was necessary, but I remember playing with a rotation when disassembling too, so perhaps it is required.
This may be the most difficult burr puzzle I’ve ever solved and I thoroughly enjoyed it. I’m not eager to solve it again anytime soon, but I do think I will revisit it one day and see if I can get a better handle on how it works. Highly recommended if you enjoy this type of puzzle – and there are even some left at cubicdissection.com
This one is waiting for me, too. I’m in that early “not quite ready to tackle it” stage. It’s pretty daunting.
A very nice write-up .
Funny how that works:) I still have a quite a few on the shelf that are waiting for the right moment… Thanks for reading!
I really really enjoyed this puzzle! This was the perfect difficulty for me. Took me about 3 weeks off and on with a combined time of maybe 8 hours to complete it. This review did help me though and had I not taken pictures/video and been aware of certain orientations it’s quite possible this one would have never made it back together. I had a very similar experience in the beginning of just random guessing and getting further (and sometimes unknowingly back tracking) through the puzzle but I now realize that there is a very specific logical (and visible) sequence that must be done and it is possible to master. I was able to take it apart and put it back together for a second time in about 10-15 minutes. I encourage anyone who owns this puzzle to go back and see if you can master it.
If anyone would like some orientation hints for reassembly feel free to shoot me an email. [email protected].
Happy Puzzling!

Great input Eric. I’ll definitely have to pull this one back out in the near future and see if I can find the same visible logical sequence you are describing. I certainly don’t feel like I ever mastered this one.
