I am new to Unity.
I am converting my Sudoku game written in WPF to Unity2D. I converted everything. However I cant achieve 9*9 grid with Buttons as I did in WPF.
In WPF I created 81 buttons with same event. So when it is called I jsut got their position displayed keyboard with only numbers that cell allowed.
Here is what I needed
1: I inserted canvas then tried vertical layout(for adding 3 rows) without success
2: Then I tried grid layout with canvas with fixable count column no success
3: grid layout with flexible option still no result.
I also tried via coding using GUI.BOX, and all still the result is not good.
How can I do it?
