I think chess is funner. It requires you to think a lot, it doesn't take too long, and it is a head-to-head battle. Unless you have a four player chess game like me.
On the back is a regular board to play with just 2 people
There are about 40-50 million different possible games of checkers. There are about 10 trillion different ways to play out the first 10 moves in a chess game. That right there shows that chess is much better than checkers.
Checkers is good for just a short game (depending on how you think out your moves). Chess is more challenging, and there are more pieces, each with there own unique moves. Also, chess has one very important piece. In checkers, every piece has the same importance. For it's diversity, I choose Chess.
Chess. Requires more strategy. Also, checkers is just annoying. With only one way to move unless you get kinged, it really starts boring and stays that way for quite a while.
The problem with all you people who dislike Checkers is that you are thinking. If you want to think in Checkers, then make your own version and add walls and different kinds of units.
Try something like Stealth Checkers, which is like Battleship but with Checkers and walls.
