Playdock was Extra's own brand arcade which replaced many Game Grid stores at Extra services. Extra have seemed to realise how effective it was to have the own brand concept, like Welcome Break's Welcome Break Gaming and came up with Playdock. Playdock specialised in arcade gaming and gave cash prizes to the winners. It was removed in 2012 in favour of Quicksilver.
