Chrome does not longer support NPAPI by default (starting with version 42, April 15), which is needed to run java applications. Java is still needed to play our Billiards games, so you need to enable NPAPI in chrome manually, if you still wish to use this browser. In order to enable NPAPI in chromeV42 please copy/paste the following address into the browser's address-bar: chrome://flags#enable-npapi then click on the small "enable" link below "Enable NPAPI Mac, Windows Enables the use of NPAPI plugins. #enable-npapi" and relaunch your browser using the "Relaunch now" button at the bottom. Please note, however, that google is planning to remove NPAPI support completely from its browser in a couple of months, so you might also consider choosing another browser to play our games.
