I know I posted something like this somewhere else, but now I just found a way to do it without my help: first login at www.challengeyou.com , then click on search (to the right) and then type New Horizons and press enter. Then under the search bar you should see New Horizons, click on it. Then under the game to the left, you will see, vote/comment/link, click on that. And then do the following: Select how many players you want (10 max). And then click START MULTI-GAME (if no one joins then the game will shutdown after 10 min). Then to join the game, click on join game above the options, and for others to join, do the first 5 steps and click join game. simple enough for you? (sorry its so complicated)
