Conquer your enemies, and the territory they hold, by typing until the tips of your fingers are raw and bleeding.
Just type the words of the hexagon closest to you to conquer that spot, and if you conquer an enemy they die. You can also easily retreat back to hexagons you've already conquered.
Don't accidentally hit backspace while trying to type. That will tell your browser to go back.
Also, accuracy is better than speed. Who cares how fast you can type if you can't type accurately enough to finish a word without errors.
