Neat idea! The computer keeps beating me with its basic strategy.

I also managed to get the die stuck on a side with an edge pointing up, to where the game couldn't choose a face. I thought it was going to brick the game, but it detected this and re-rolled the die. Nice!

Totally changes the game for me. Makes it so that you (almost) never want to play the middle square unless your hand is forced.

Also reminds me of how I was playing Senet last night. I controlled the game until the very end, where by chance, I kept rolling "bad" numbers and my opponent kept rolling "good" numbers.

Middle square is actually pretty good. Solid odds of the opponent giving you a layup with a bad break.

Brilliant! Makes a simple children's game very interesting. One aspect I really enjoy is that it makes clear the knee-jerk response towards action bias[0]. There are times when your opponent has two-in-a-row, but the probability of a frown on the third is > 50%, in which case it's in my interest to have my opponent click on the third square instead of me (but even knowing that cognitively, it's still hard to not action).
