Nic Gregoriades of Jiu Jitsu Brotherhood has been working for a long time to bring you this handy digital grappling tool. It is especially useful for beginners trying to figure out what to do in specific situations. Your options change with each roll. Your correct actions are rewarded with points and eventually a submission, and your bad decisions yield bad positions to work out of, or you will be submitted! Clear goals are laid out which allow you to advance in belt ranks.
You can try it out with just an email address and for a limited time you can sign up for under $5 dollars for one month! Check out the demo video below. Click here to try it out!
