It is very likely forbidden, even more so for Sedaradim but even according to many Ashkenazi decisors.
For background (adapted from R Moishe Dovid Lebovits here)
The Mishnah in Maseches Sanhedrin 24b lists people who are disqualified
from being a witness. One of them is a “mesacheik b’kubiya”, a dice
player. The Gemara discusses as to why a dice player is disqualified
from being a witness and brings two opinions.
One says that a winner is considered stealing from the losing party.
This is called asmachta, which means doing an action under the
assumption that he will never have to pay (each gambler agrees to pay
but never really thinks he will lose, so when he hands over the money
to the winner it is done unwillingly. This action is considered
stealing on a rabbinic level.
The second says dice playing is not allowed because one does not
contribute to society that way. Therefore, he is only disqualified if
gambling is his only profession. If he has another profession, then he
is only gambling to pass time, and does not care if he loses.
The Shulchan Aruch holds that gambling of any sort is considered stealing. This is how the Sephardim conduct themselves. The Rema permits it but with many limitations: there should be no skill involved, the gambler must not feel secure that he will win and the result must be based on luck.
Since chess, board and card games are skill-based, they would be forbidden.
In addition, R Moishe Dovid Lebovits brings many poskim who raise societal reasons to stay far away from gambling
- The Rivash says that gambling kills people. It is
disgusting, abominable, repulsive, and it is addictive.
- The Biur Halachah says that someone who is concerned
for his soul should distance himself from gambling.
- The Aruch Hashulchan says that whoever can stop from
gambling will have great reward.
- R Moshe Feinstein said that it is a disgusting act
and is like joining a gathering of scornful people
