Create or modify current spot the ball competition for square space site

We need to be able to take a high res image and allow people to select pixels…to create a game of skill. ‘Spot the ball” The method should be by using mouse/cursor to roll over the image then click and select a pixel That position is then stored as the pixels coordinates as part of the ticket purchase or even as the Unique purchase number… You must have high level of experience and be able to test the game to remove faults bugs ect. The game must be able to have durability able to be used thousands of times a day and be compatible with square space These coordinates(ticket numbers) will be stored securely with the purchaser's name and details until the draw is made. The draw will allow someone, the judge to place their first choice as if a player. Then the program should be able to list the next 100 picks closest to the winner in order of closeness. This gives us our winners in order… if that is required. We need it to be able to hold ten choices at one time. So people who buy multiple tickets can do it quickly, and easily by clicking 1 Then another then another etc… They should also be able to easily deselect a choice, and select another before they make thier final selection. I.E. If someone buys ten tickets they will get ten chances to spot the ball. But they want to move 2 of the choices before finally selecting. So they would click for a second time to re-select a previously selected point, maybe it would turn red, then a small banner would come up “click again to remove selection” if they do click again that 1 selection is deleted. They then could make another. So, in essence, it is an image pixel picking and data storage program/game. high durability bug-free
