On-Site Doubles

 This site has a very different head. Once  you have made the settings you want from the menu on the right side of  the main screen, you can create a chaos environment by clicking fast on  the faded balls on the opposing balls (they may be emoji, balloons,  plastic balls). Do not be surprised if you find that this site, which does not seem to have a lot of numbers, is suddenly addicted :)
