During the Cologne 2015 CS:GO Championship, players had the ability to participate in The Cologne 2015 Pick'Em Challenge. Much like The Dreamhack 2014 Pick'Em Challenge, players were able to buy directly the team stickers they want to pick winners of upcoming matches. In addition to the normal team pick'em challenge like past events, players can also use stickers from the ESL One Cologne Player Autograph Capsules to participate in the player pick'em challenges, in which individual professional players are picked for various individual achievements during the stages of the tournament.
Similar to previous pick'em challenges, the ESL One Cologne 2015 Legends (Foil) and ESL One Cologne 2015 Challengers (Foil) capsules were available to buy, containing Foil versions of the team stickers. 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.
The Pick'Em Challenge Trophy
During the tournament, choosing the winning team granted the player points towards his or her Pick'Em Challenge Trophy. There was a total of 200 points possible, received by correctly choosing every winning team throughout the tournament, correctly choosing MVPs of particular player stats, as well as earning a single point per pick'em challenge per day just by participating. All trophies were awarded after the tournament has completed.
