Gambling has long been outlawed in the islands, but that hasn't stopped people from getting their fix.
Illegal game rooms are also hot spots for violence.
Police arrested a 28-year-old man for a deadly shooting at a game room off Kapiolani Boulevard.
On Saturday night, police say Manu Sorensen and another man were trying to rob the place when Sorensen shot someone inside.
The victim, identified as Jacob Feliciano, 31, of Waipahu, died at the hospital.
Just one week ago, police responded to a shooting at what they called a game room on Palama Street in Kalihi.
We're told the suspect, Kilani Derego, 26, pulled out a gun and demanded money.
As he was getting away, two men went after him and the gun went off three times. No one was hurt.
Derego was arrested at the scene.
