Playdock is Extra's own brand which have replaced many Game Grid stores at ExtraMSA. 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 specialize in Arcade Gaming, they have arcade games and give special cash prizes (£500-£1000 if more) to the lucky winners. Playdock was removed in 2012 in favour of Quicksilver.
