In order to open the pack just press on them. The cards are actually from FC 26. Mini game is a little wierd right now. If the music stops just go to settings and turn it off then turn it on.
Sorry guys that the cards are not from FC 26 since the TOTS just came out and I am waiting for them to finish. Nice game by Leon50lk. Game is still in progress. It will take over a month to change the cards since TOTS are coming out.
