This would be a timed game. The winner would be the robot with the lowest average
time-per-move.
Actually, I was just thinking about it. Even that may not be a good comparison. I
think robots should play each other twice, with each going first one time. The
winner is the robot that wins the most games, or has the fastest total move time,
over two games.

There are lots of other games we could play, with much more complex strategies. I
think 3T... (the name for this game?!) ...is a game that everyone can understand
the logic, and it should be playable with standard firmware.
The challenge is not playing the game, it's building a robot to play it, and play it
quickly.

I like the idea of having cube-shaped cubes. I was thinking it would be cool to
have a contest that sort of required everyone to build big robots. Those are more
fun to look at. So, 6x6x6 would fit that. But, I'm starting to think 4x4x4 would
be OK.
Anyone else?...

I do like the idea of using a 32x32 board. It's easy to transport.

Let's not talk about that. I need to get back to work.

| (...) What about Othello? That requires the robot to be able to place AND reverse the pieces. Not sure if 8x8 would produce very interesting matches, maybe a smaller board? Even 4x4 may produce interesting strategies... ROSCO (19 years ago, 29-Sep-05, to lugnet.org.us.laflrc)
