> An believe me this is not a puzzle , not a game
Nothing wrong with games... so can you explain what is is you're trying to solve?
My problem is that this also seems to be a solution:
1111772222
1111772222
1111882222
1111882222
553333
553333
663333
663333
Is that allowed? If not, what's the rule that prevents it?

hmm... that fails on the row where you meet the 5s and 7s - your WHERE would need to find all 8 members for that row. Need to shift up those 3s...
