Black Hole Blues
Quark accidently asked the replicator to "generate a black hole" instead of "make a black hole (the drink)" and spaghettified the promenade. Odo accidently married an ambassador and spends the entire episode trying to trick her into legally divorcing him.
Meanwhile, Dax and Bashir have gotten really into this old earth game, Beyblades™. It's starting to affect their work, and in an attempt to prove how silly the game is, Sisko winds up also falling in love with letting it rip.

With Odo preoccupied, it's up to Kira and O'Brien to figure out how to free the other officers from the game they're now spending all their time playing. As it turns out, we later learn Quark actually bought some new gambling machines off shady dealers from the Gamma quadrant, and that they aren't actually Beyblades™ but alien tech designed to immerse you.

While trying to crack open a device to rig the game in the house's favor, he accidently destroyed the warp core inside powering it. Now the energy and desire to gamble has been leaking all over the station. The episode cuts to credits before this is resolved, 6.5/10.
