Stickers are a communication feature introduced in Playtest 2. It is used by players to express themselves towards other players in various ways. Holding down the G key pulls out a wheel that displays up to 8 stickers the player owns. To use a sticker, the player must move their mouse to their selected sticker and release the G key. When used, the sticker appears above the player's head for a few moments.

Most Stickers can only be earned by obtaining Badges. Good Job is the only sticker that is unlocked when the player initially begins playing.

Stickers are created by the boggio development team, or contributed from members of the community.
