I wanted to disable a repeat selection of an ImageSprite after the ImageSprite.Picture is selected (set) on a canvas. But this did not work. What could be the reason?
Maybe you needed instead a separate Sprite Touched event for each Sprite?
Use those instead of the Canvas Touched event.
I added a separate Sprite Touched event and set the ImageSprite Enable to false for each ImageSprite. Didn't work. 
This looks like a three by three grid.
Are you coding tic tac toe?
Buttons in nested horizontal and vertical arrangements would be easier.

Screen scraped blocks lose resolution and become unreadable.
AI2 generated block images are SVG, which are readable under magnification.
Please download and post each of those event block(s)/procedures here ...
P.S. These blocks can be dragged directly into your Blocks Editor workspace.
See
for how to download individual draggable block images.
p.s. maybe you forgot to increase the turn number?
I think your issue is the nested conditions inside if..else blocks. There are too many nested if..else going on. Perhaps debug carefully. Hard to say from the screenshot alone you posted.
