Particles are in motion in Brownian Motion. Each particle is assigned it's own value. If you get two particles of the same values to touch each other they will begin to blink for a few seconds. You are able to merge such equal particles while they are blinking - click on a blinking particle to merge them. After beign merged, particle value increases to the sum of the two merged particles. Your end goal will be reaching a score of 2048. As you play the game you'll be treated to live action video clips of XXX action. As you clear levels and move on to higher levels, the games difficulty will ramp up, but at the same time, the content of the XXX video clips will get all that much more naughty and nasty.
