They are built based on the previous Square-1 and Square-2. With little modification, we created the Square-3 H-Plus with the core and parts of them.

The quality of this puzzles are good and do turn smooth. You have to retain the sticker color as original stage to solve them.

You won't regret to try and play them on hand. We shall have black and white versions.
 
ENJOY!
