Moorfields said that the remaining 75 stores will remain open and operate as per usual "until further notice".
"We have made every effort to secure a buyer for all or part of the company's business", Simon Thomas, the joint administrator for the British arm, said in a news release.
"We are grateful for the hard work of Toys "R" Us staff during this difficult period, and will be providing support where we can to those who have been made redundant".
Another added: "Toys R Us was THE most exciting place as a kid".
Toys "R" Us said on Wednesday that it would close all of its stores in Britain after failing to find a buyer, another ominous sign for a once-dominant toy retailer that has struggled under pressure from Amazon and other online sellers.
Attempts to sell the business have failed, meaning that the retailer will start plans to close down all of its 106 United Kingdom stores.
Moorfields Advisory were appointed at the end of February to begin "an orderly wind-down" of Toys R Us, the BBC reported.
All Toys R Us stores in the United Kingdom are to shut following its collapse into administration last month.
From a retailer's perspective, not only is it sad to see a high street institution face the harsh reality of an online world, but those with outstanding gift cards will also be left empty-handed.
"The closure program for the remaining stores is expected to take approximately six weeks to complete with further announcements to follow", the company said in a statement. Those sales were extended on Tuesday and products are being offered at discounts of as much as 30pc.
'Now is the time to check what redundancy rights you have and dig out any income or mortgage protection policies you hold.
Today (March 14) staff were informed that no buyer had been found and so they would need to start the hunt for new jobs. "Toys 'R" Us are no longer accepting items for exchange or refunds'.
