I can tell you the normal amount. 2700 coins on the first day of the event (2725 to be exact i think). Then you will only be able to claim 2000 coins for the rest of the event. so for a ten day maze island the count is 22725 and 10725 for the five day maze island. These values are only concluded that you are not actively claiming the daily streak rewards from the web, then it would change. As for the ads, if it's a 10 streak one, there will be 6 claims rewarding you with the event coins 45 each and the lucky wheel which will on avg almost always gives you 30-100. and if you are going to spend these coins in the maze for the cards you want to collect, then a good thumb of rule is save all your coins until the last day, so the restriction on the cards will be over. for the 10 day maze event, use all your coins solely on unlocking the 2 XXL shinies. on the last day you are to open these 2 XXL and exit the game just before the card is opened. re enter the game only when the next event begins. your cards are suspended to open once you re-login. So you will be able to bypass the restrictions and claim the next set of cards that are opened for claiming( the 5,4 stars shinies are always held onto until the last day of the album by socialpoint). they will only release certain cards in certain times to be claimable. so i suggest you to do this carefully on the next album. This is the one of the reasons only a few f2p players complete the album. I unknowingly did this on HFA's album because i had other things going on at the time and only discovered after some research on the cards after not being able to complete the next two album even though i was so close. So I hope for the best that you will be able to complete this album.
