Betta Fish: How can I “play” and interact more with my betta fish?

Get a China marker and draw a big tictactoe on the glass, give your fish an x or o for whatever box they swim into. Someone did a video somewhere…there was a post on Reddit also.

Write the alphabet on the tank and play fish hangman. See what your fish spells.

Write a bunch of numbers and write down what he swims up to. Play those in the lotto.

Edit:deranged typos

I cut out teeny pictures and show them to my betta. Once he seems interested in a few, I tape them to his tank so he has his own art to look at (hint, cooler colors and things that wouldnt be mistaken for eyes are perfect, mine actually like geometric designs and two colors stacked i also try to spend time letting him get to know my voice and face, sometimes ill bring home plants or new stones or gems and sit at my tank just talking to him calmly the whole time. I just say out loud little stories or what im actively doing and why, etc etc. Since fish hear you via feeling the vibrations through the water, I try to speak like how I would want a wall of vibrations to have a smooth ripple instead of sudden and choppy. Also, dry erase markers. Sometimes I draw a little house with windows or little “maze” parts or plants or just interesting shapes for him to follow and inspect. Also, before I add a new plant or anything, I will hold it up against the glass for him to check out, then I place it i slowly. He waits so nice and watches then when im out of the water he will go and touch it.
