Flopzilla is a poker calculator that has been designed to let you quickly and easily figure out how a range hits a board.

Just enter a preflop range and a board and Flopzilla will work out for you how often that range hits hands like top pair, middle pair, a flushdraw, a gutshot, etc.

The interface is designed to be quick, easy to use and intuïtive. The calculations themselves are so fast that a "Compute" button is not even necessary. Just make any change and the results will instantly adjust.
