I love it when a very simple (and free) web-based game can just capture my attention for the better part of an hour. Good thing that I’m not at work right now with this thing. The concept is very simple. Time your release of stones thrown with a trebuchet to knock down walls, decapitate soldiers, and bring down the king. The big trick in the harder levels is to take down the flag. That’s how the Europeans conquered the world and that’s how you get big points in this game.
