The 23-year-old Hungarian joined the Foxes from Portsmouth last summer, making 12 appearances in all competitions for the East Midlands club.
He becomes Paul Ince's second signing at Bloomfield Road following the loan capture of MK Dons defender Gary MacKenzie on Saturday.
Futacs could make his debut when Blackpool face Birmingham City on Tuesday evening.
