ah very sorry about the dialog being too large. Which phone have you used it on? I should really fix this.

I've tested on an iphone mini, and even though the dialog is quite big on it, so I should indeed try and shrink it, it doesn't prevent completing the tutorial. But it looks like I wrongly assumed this would be the smallest phone I could test it on.

And as far as I know, the empty tiles only gets uncovered if you uncover another empty one, so I followed this principle. If that was also the case when you uncover a number, this would reveal too much.
