Awesome Maverick1912 Thats work fine now for horizontal, vertical and square at the same time.
Thank you very much you are just amazing and very helpful to this Forum.
I am noticing one other feature of the original BlockuDoku game:
When i move a tile over the playing grid, it casts a "shadow" over the fields where it can be placed.
There is also a visual hint of the line, square, or combination that will be removed if you drop the tile at a particular location, even before the tile is dropped.
I would really like to have this implemented. Would it be possible?
Thanks once again
