The Newly Improved Tonai.net

Trying to get back into coding more regularly (life has been a little hectic), so I'm starting with some Project Euler problems. Since this is just a warm-up, I decided to start with an easy one, and selected #112, the most solved problem published after the first 100.

Bouncy numbers go up and down. The consecutive digits increase and decrease, like 1234321. Or just 121. But not 123 or 222.

Pentago is a two-player game that is described well enough on Wikipedia.

I am working on a Pentago AI, codenamed Mistletoe, as a programming project.
