Spot The Ball Software

Hello,

I am looking for a game to be designed which is spot the ball.

- An image will have a picture of a ball in.
- The ball will be removed
- People will then try to pin point the middle of the ball
- It will need to record the position that person has clicked
- It will need to record this in a backend system so we can judge who is the winner of the competition
- Photo will need to be updated/changed for each competition period

Thanks
