Amazing! The coloring came so easy I thought it would fall quickly. But I was anchored on an incorrect set of digits for the solution. Once I let go it finished quite nicely - very rewarding, thanks!

Very elegant puzzle, I didn't expect to be such logic remaining once coloring was finished, but was quite surprised with the beauty and quantity of it!

What a ride! Used both colours and letters to fill in the grid. The endgame logic was clever. Thanks, @ Scruffamudda :)

It's not too difficult for me to get used to the coloring method, but this is the most pleasant puzzle I've ever seen. Whether it's the coloring of y and z or the coloring of v and x, it's perfect from the beginning to the end, and it's even a pity to solve it.

This was incredibly hard for me, but good fun nevertheless.

This has quickly become one of my favourite colouring puzzles. Not knowing how many possible Y or Z dominoes there are at the start had me saying things aloud like "if blue exists then..." which is one of the funnier things to say. Thanks Scruffamudda :)
