Dice is still popular game in the crypto gambling industry. But people don't use bot a lot on dice game as they used to do it before. The taste of the gamblers have changed, now they prefer slots game more.

AFAIK, dice is the only game where we can use bot through the API access or username and password. Maybe it is possible to use bot on some other games too, but I never heard anyone to use bot for other games except dice.
