The one and only free poker m zone calculator on the market, optimized for fast decision making.

Based on Dan Harrington's M Zone system ratio (http://en.wikipedia.org/wiki/M-ratio), this poker tool allows you to quickly calculate your current M Zone and Effective M Ratio, once you know your M you can adjust your strategy. In tournament poker this number tells you is how many more ‘rounds’ of the table you can survive without being blinded away.

Stack, blinds and player number can be modified without time consuming text input giving you more time to consider your play instead of waiting for calculation.
