Crossing off items
It would be great to have a type of feature to be able to place an "X" over set places in an image. For example, the user needs to search for different items in their surroundings and then be able to "X" out or cross it off of the board or page made with those items on it. I am attaching an example of what is to be a travel bingo game board that I would like the user to be able to place an "X" over an item after they have found it.
If there is anything that could be used to do this that is already created, I would love to hear how that can be done! I have tried a few things, but have not succeeded!
