Rocket Game

RocketGame sits on the TRON blockchain and allows players to either play against each other, or the house directly and win TRON tokens:

They've got 4 games that you can play against other players and 8 solo games. The Monopoly version actually looks pretty good, although I'm not sure how long those games must take. The whole time I was looking at this site the Bets section was constantly moving and it looks like about 1500 users are on the site every day.

You can see who is on the tables, and who are on the table waitlists... it honestly looks pretty well set up.

Looks like the devs are pretty active, so should help retain all those users and transactions. Obviously only gamble what you can absolutely afford to lose. They say it's provably fair, but I wouldn't 100% trust that.
