Stickers are an essential resource in Monopoly Go, but unlike dice and cash, they cannot be purchased directly in the game. You can only get them by participating in frequent in-game events and completing challenges. Collecting as many Monopoly Go Stickers as possible is essential to complete Sticker Albums, especially when rewards are offered. Completing an Album earns you dice and cash, which are Monopoly Go's most valuable in-game resources, as well as snazzy in-game tokens.
A Wild Sticker is a fun card that allows players to pick any Monopoly Go Cards they are missing to complete a Card Set. These Cards include all tradable Stickers, as well as non-tradable Gold Stickers. However, players cannot save their Wild Stickers and choose Cards later. They must make their choice the moment they get the Cards. Wild Sticker Cards add a new dynamic to the game, allowing players to pick up the stickers they must need to complete their Albums and advance in Monopoly GO.
When playing Monopoly Go, you will quickly notice that there are different colored Card Packs. The color changes aren’t just to make the game more visually appealing, though - the colors indicate the rarity of the cards within the pack, as well as how many cards are in the pack. Monopoly Go Cards Packs come in five different colors, each offering a different number of cards and a higher chance of getting rarer cards. Green Card Packs are the most common Card Packs, containing fairly common cards that are often repeated, while Purple Card Packs are the rarest and have the highest chance of unlocking new cards in Monopoly Go.
