Monopoly GO spices things up by introducing a new Sticker Album every few months, giving players a fresh set of collectibles to chase and new rewards to earn. As you play, you'll randomly receive stickers. Each sticker belongs to a particular set within the album. Once you've collected all the stickers for a set, you can complete it. Completing a set rewards you with exciting prizes like dice rolls, cash, and exclusive tokens, shields, or emojis.
