Welcome to the ReadTheWest.com's
The object of the game is to roundup as many critters as you can. The cowboys are able to headoff the cattle and stop them from advancing by "jumping" (as in a regular game of checkers). This automatically sends the critter into the corral - but don't let 'em turn on you. 'Cuz once one of 'em reaches your end of the Checkerboard Range and are "kinged," they then get mighty full of themselves and have the ability to move forwards or backwards across the range, making a real mess of things.
The good news is once each of the cowboys in your outfit makes it to the opposite end of The Checkerboard, he has proven himself and earns his spurs. He is "kinged" and receives a new lariat to catch those rangey critters and his horse is allowed to lope forwards or backwards across the pasture in order to get the job done.
Good luck!
See ya' back at the bunkhouse.
