About the Pokernator 3000

The Pokernator 3000 first went online in April 2004 at pokernator.com, a free Texas Hold'em calculator written as a Java servlet. You entered your pocket cards, then the flop, turn, and river, and it told you which hands you were beating and your chances of improving.

2004

• April 1: launch, with a forum for discussing hands and (legal) home games.
• April 3: mouse-over counts of the hands beaten, tied, and lost to by category. That's the “Breakdown by opponent hand” today.
• April 4: a full rewrite after a bug mixed up the hands of two players using it at the same moment.
• May 13: straight odds fixed, and the open-straight stat pulled until a better algorithm existed.
• August 6: the open-straight stat returns, “dead on”. An outs counter and player-count features were next on the list.

2026

This version is a rebuild from scratch: the same tables, computed in your browser by an exact TypeScript engine, with nothing sent to a server. It keeps the 2004 numbers (the test suite checks them against the original help page) and finally adds the planned player count, as showdown equity against up to nine opponents.
