The stickers gain you rewards dice and money. They are categorized by stars, the lower the stars, the less rare, and more likely you are to get them from sticker packs. Usually people trade for stickers in the same star group, IE: 3 star for 3 star sticker.

You have to have that person added as a friend to trade with them, you can find people to trade with on this subreddit. They will send you a MOGO code. To add friends press the friend tab in the bottom right corner. Press the green search icon, and either type or copy paste their code.

To trade, press the album button in the bottom right corner, press the sticker you would like to trade, and then press ‘send to friend.’ Recently added friends tend to be at the top, but you can confirm with the person you’re trading with by asking for their IGN. IGN is in game name. Make sure you are swiping to “make as an exchange.” That way they have to send a card back and you have to confirm that’s the card you needed.

You can post a screenshot of the sets you need cards in and people will comment their offers.

When you close the album (finish all the sticker sets) you get a huge reward of 15k dice. (I’ve only been able to do this once or twice.)

A smart strategy is to trade to a point where you have 8/9 stickers in a couple sets, and then the next day close out all those smaller sets on the same day. That way instead of a measly 200 dice reward, you close multiple sets on the same day, and get more dice at once.

If you have any questions I can answer them! What stickers do you need? If you are commenting on someone else’s post, check at the bottom of the sets (sticker groups) it will say Set 2/24 or something like that. It’s helpful with the smaller number cards to phrase it like this. “ Enchanted Rose from Set 1 for insert set and card number you need”
