Every cell in the 6x6 grid contains one of four letters, namely, A, B, C or D. No letter can be horizontally or vertically adjacent to itself. The tables above and to the left of the grid indicate how many times each letter appears in that column or row.

Can you complete the grid?

Hi josie

I'm a first timer. really liked your problem. Got it right at first attempt but i'm not sure if it was luck because there seemed to be 3 other options once you eliminate the letters which are not allowed in whichever column/row. Am I right, was I lucky or is there something I'm missing?
