This puzzle is very difficult because it has many pieces, and the initial placement is not obvious at first glance. It cannot be solved without identifying the key trick. It took me about three hours to solve it. It truly deserves the title of 'extremely difficult'. The solution is unique, and I am impressed by the creator's ingenuity.

As an aside, here are some suggestions for other puzzles using this one without the frame (using only the pieces):

①Create a 3x3x3 (27 voxels) cube using five or six pieces.
Difficulty level: Easy

②Create a 4x4x3 rectangular prism using all the pieces.
(All surfaces are covered with blocks, so there is space inside.)
Difficulty level: Hard

This puzzle was much more difficult than it appeared. It required strategic thinking and experimentation. Although the goal initially seemed unattainable, understanding the possible movements of each piece enable me to steadily reach it. The solution is both elegant and satisfying. I would highly recommend it to anyone looking for a challenging puzzle.

As a side note, I created a new puzzle and named it “BONBON Lion“.
The necessary pieces are as follows:
・L-shape: 1
・i-shaped: 1
Split the I-shaped piece (4 voxels) into 1+3 voxels.
・Square: 1
・N-shaped: 3
Total of 7 pieces (24voxels)

If you have these pieces, you can put them all into the BONBON box.
Difficulty: Extremely difficult

I like the TriadTIC a lot.

I'm writing this review even though I haven't actually finished the puzzle yet.
Honestly, I didn't expect it to be this challenging, considering it only has four identical triominos. I tried simulating it outside and tinkering around it inside and then I've gradually learned what I can and can't do. However, I still can't figure out how to solve it.

What on earth am I missing?

I would recommend this puzzle to anyone looking for an extremely difficult one.
