How do simulate a scrach card

Hi, I would like to build a scrach card, like the paper ones you use a coin to scrach off the silver foil to reveal the symbols underneath.

Im guessing I could have two layers - the "foil" and the symbols. I would then need to have the cursor change to a coin when over the scrach area, and for it to make a swath of foil pixels transparent without clicking (So it can work on mobile with your finger).

In addition, I would need to be able to work out when a certain percentage of all symbols had been scrached, to show the prize.

Any tips on how to approach this with construct 2?

Many thanks!
