Who knows, perhaps there are some people who would find luddo appealing,here it used to be a very popular game during long travels and family meetings to play while having some drinks/snacks. Also, even though the percentage is high, it served as an example on how casinos could earn money with tabletop games in general, this same model could be applied to chess, Monopoly-like games, memory games,etc.
I must admit though, that luddo and similar kind of tabletop games have fallen in popularity in favor to mobile games, handheld consoles and other forms of electronic entertainment.
There's an app on Google Play, Ludo King, I think it's the game you are talking about, right?
From what I see, it's a very popular game in India. It has been downloaded more than 100 million times, and videos about it on YouTube have millions of views. The DAU (Daily Active Users) of this game is between 10 million and 70 million monthly users. And the game isn't popular only in India, it's quite popular in other countries too. Look:

I myself can't figure out how to play it, but it appears that many millions of people know and love this game, so, it looks like a good idea to add Ludo on online crypto casino.
I play this game a lot in my spare time, I can say it is an addictive game but I dont think it will be an attractive game if I have to gamble with this game. Why? Simply because it takes long time to finish a single game especially if we play in 4 players game. It will be not really worth for small gamblers to spend too long time for a single win. The most possible gambling concept for this game is a PVP based game where players against other players to win the collected entry fee in the game.
