Pick'Em Challenges allow users to wager stickers on participating teams during select official championship tournaments for trophy points.
During specially selected Valve sponsored championships, players have the ability to participate in Pick'Em Challenges. Players can use team stickers to pick winners of upcoming matches. Prior to the DreamHack 2014 Pick 'Em Challenge, stickers were acquired by purchasing a team sticker pack, giving the user a random sticker upon opening, but was changed to allow users to buy stickers directly from the store based on the team picked. Stickers from previous Team Sticker capsules or collections do not carry through to the next challenge. Picking a team with a team sticker during the tournament locked the sticker and made it unavailable to use, trade, or sell until the event day was complete. Undoing a pick did not unlock the sticker until the event day was complete.
