🌟 🌟 🌟 🌟 🌟 5 star review from Bill: A TrICky Twist!

A very nice introduction into the many varied TIC line. Not the hardest, not the easiest. This one is a five-piece, with the first couple pieces trying to Trick you into thinking this one will be easy. Not so! The challenge is in the remaining three pieces, requiring attention be paid on their disassembly. Most heartily recommended, as is the whole TIC line. Enjoy!

🌟 🌟 🌟 🌟 🌟 5 star review from Hiro F: Unique solution!

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

🌟 🌟 🌟 🌟 🌟 5 star review from Hiro F: Insanely difficult！

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.

🌟 🌟 🌟 🌟 4 star review from Hiro F: Satisfying puzzle

I tried this puzzle after completing Alpaca 1. Personally, I felt that the difficulty level was almost the same as Alpaca 1. It was challenging, but I overcame the obstacles using strategic thinking. To make it easier, I put a marker sticker on the top k**b. I preferred the previous color version, so I gave it four stars. Overall, it's a very satisfying puzzle.

🌟 🌟 🌟 🌟 🌟 5 star review from Hiro F: Great!

It took me about forty minutes to solve this puzzle.

It looks like the "JIGS4W" by Haym Hirsh which is a four-piece packing puzzle but its restrictive frame makes it more challenging.
Solving it required both observation and a bit of dexterity.

This puzzle is full of brilliant ideas!
