During the ESL One Cologne 2014 CS:GO Championship, players have the ability to participate in The Cologne 2014 Pick'Em Challenge. Prior to the tournament matches, players could use team stickers from the ESL One Cologne 2014 sticker capsules to pick winners of upcoming matches. Stickers from the ESL One Cologne 2014 Challengers and ESL One Cologne 2014 Legends were available to use for the 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.
