Mr Howe, 24, beat odds of more than 93 billion to one when his 15-number full house came in after just 23 calls.
His win came just 40 minutes after he opened an account on the William Hill Bingo website.
Experts have now contacted the Guinness Book of World Records to see if it is the fastest full house ever.
Mr Howe, of Moreton-in-Marsh, Glos, said: ''I guessed it was just beginners luck when I won.
''But I was totally gobsmacked when William Hill told me how extraordinary the game was and the odds of that happening. I might get my name in the record books.''
Jennie Prest, a William Hill Bingo spokeswoman, said: ''None of our staff or customers with vast bingo playing experience have ever seen a game unfold as quickly as this one.
''We believe it is a record and are exploring the possibility of getting in the Guinness Book of World Records.
''We can't find examples of a quicker 90 ball game, but are interested in hearing from anyone who knows more – at those odds, it must be very rare.''
The odds of getting a full house with 15 numbers in 23 calls in a 90 ball bingo game are 93,400,706,414 to one.
