It seems nonsensical to propose that a bingo-based game could be copied, but in the case of Buffalo Studios' Bingo Blitz and Zynga's Zynga Bingo, the evidence is rather clear. "We wanted to alert you to the striking similarities between Zynga's recently announced game, to our game Bingo Blitz," Buffalo Studios VP of product marketing and operations Salim Mith told Venture Beat. Mith also offered a cheeky visual letter addressed to the Facebook game publishing giant, comparing images of Bingo Blitz to those of Zynga Bingo to highlight the similarities (seen in full after the break).

The letter comes just five days after Tiny Tower dev NimbleBit created a similar visualization to address what it perceived as a copy of its building management sim in Zynga's Dream Heights. Zynga has yet to respond to copycat allegations from either NimbleBit or Buffalo Studios, but it's also possible that the publisher simply can't hear the complaints over the din of its coffers being filled.
