Adding more games is a good way to attract more players because dice is the most boring game. Where there are some other games then it is usefull for players to kill the boredom. They can switch to other games when they feel boring for dice. Nowadays it is very common for a dice site to add more games, e.g bitsler, bitdice, crypto-games.
Without a doubt, more games = more players = more wager.

But i believe that on bitsler, people are more concern about their dice rather than other games, because mostly people will play and earn everything from their dice not from other games like multicolor or anything like that. And actually it depends on the site itself but most of the sites will want to get more players on their sites so by adding more games it will be more players. And they really need to make the attractive one to make people want to try their new games.
