While not actually a flop game, it is similar in that it has 5 community cards in which to make your hand. Unlike other flop games, however there are x main differences:
The deck is shortened to 32 cards.
The community cards are dealt one at a time including the first one, dealt immediately after the initial deal and before the first round of betting.
You must use exactly two hole cards and three of five community cards to make the best hand.
The betting structure is based on the size of the blind. The first 4 rounds are at 2 x the blind, and the last round is at 4 x the blind.
Blinds:
Only one blind is used and this is placed by the person to the left of the dealer.
The blind can have a choice of blinds to bet, and the structure of the game will adjust accordingly.
In the first round, the first raise will be 2x the blind on top of the last bet. ie, if the blind is 2, the first raise is to 6.
Variants:
3 Card Manilla - Played exactly the same except players get three hole cards and must use two of them and 3 on the board.
