17 March user submitted puzzle
Thank you, kozibrada, for this new puzzle
, it's very amused and interesting.
The answer to your extra question is no. If I am right, the left puzzle itself, the all-multiplication cages, has 4 different solutions, just by swapping two pairs of numbers, the 5 and the 7, and the 3 and the 4, when the grid is almost full.
The all-addition cages puzzle itself, in the right side, probably has a really big number of solutions, to find them all we would need the Patrick's software cooperation (so, in a few days, I am sure Patrick will tell us).
