You only use your mouse to click on the open a pack button. Then, select the pack you want to open and tap or click and hold the button to open it. The counter at the top right determines when you get more coins (25 coins every 15 seconds) After you open a pack, click on a card to proceed. You cannot sell your cards. Opening a regular pack costs 25 coins. Opening a gold pack costs 250 coins. Regular packs have normal card pull rates. Gold Packs are guaranteed to have an EX or higher and can contain cards from any of the packs of that set.
I used images of Pokémon from Google and the Pokémon database website. Also see this project by kiptonbescratchen https://scratch.mit.edu/projects/1183184165/
