Today Intel is offering the final 500 spectator passes on a first-come first-served basis. Once these passes are taken the CPL will permanently close the spectator category of the online registration.

These special spectator passes allow free access for five-days to the following activities and areas of the CPL Summer Championship Event: music concert, exhibitions, side-tournaments, workshops, spectator arena, and more. The purchase value of each pass is $25.

If you plan to be there, you better sign up for your free pass.
