The loyalty scheme has been reactivated by administrators, where points can be spent in-store but only against pre-owned stock.
Points can also once again be earned, from both purchasing new and pre-owned items.
It was added that this is only valid for Reward Cards and not store credit and gift cards, although it is currently "working on it".
GAME and GameStation halted the use of Reward Cards shortly after the retailer went into administration earlier this week.
It has been rumoured that an RBS-backed consortium will buy GAME and pull it out of administration as soon as tomorrow.
The GAME Group has shut the doors of 277 of its 609 shops in the UK and Ireland, laying off around 40% of its workforce, or around 2,104 employees.
GAME CEO Ian Shepherd resigned from his role with immediate effect after administrators PwC (PricewaterhouseCoopers) were appointed to handle any potential sale.
