Problem to generate a sudoku

Hi,

I'm a little lost, and blocked with Construct2 problem.

I am developing a Sudoku, and generating a series of numbers the browser with 25% of CPU crashes.

Attached as genre at random series numbers. Also I begin to think that the event to check if a value is in an array, not very optimized.

What do think? Any help? Thanks.

Since you're using a while loop I'd guess you have an infinite loop somehow.

One thing I notice is if 9 is ever needed it won't work since

floor(random(1,9)) will only give values from 1 to 8

Why?

random(n) will only give values from 0 up to but not including n.

Instead you should do floor(random(1,10)) if you want 9 included.
