This time waster has to qualify as one of the strangest ones we've covered. Rose & Camelia is a strangely compelling browser-based combat game. What makes it odd is that it's a slapping game. Basically, you attempt to slap the daylights out of your opponent before they do the same to you.

While the quirkiness of this concept would probably be enough to be worth checking out, as it turns out the gameplay is interesting as well. To perform a slap, you need to wait for the opportunity to click on Attack button, then move your cursor quickly in an arc up and across the face of your opponent. To dodge an opponent's attack works much the same; you press the Evasion button, then make an arcing movement away from the attacker.

Now, drop what you're doing and pick yourself a slap fight. It might be the most fun you'll ever have getting slapped around.
