Zynga game cards make it easy for consumers who don’t have access to credit cards or bank accounts to buy in-game items. The £10 cards can also be purchased as gifts and can be redeemed for in-game currency to get items like tractors, energy packs and furniture. Game cards can be redeemed through the games on Facebook, as well as on FarmVille.com, MafiaWars.com and YoVille.com. All Zynga games are free-to-play online, and players can buy virtual game items from villas to spice racks to decorate their farms or cafes.
