We first find the game in the season 5 episode 'Business As Usual' where Dax and Quark are playing while Gaila tells Quark of the benefits of selling weapons.
Later, we find it in the season 5 episode 'Ferengi Love Songs' where Quark discovers his mother has been seeing Grand Nagus Zek, and they are in love. Seeing this, Brunt hatches a plan to become Nagus with the help of an unknowing Quark
Again, this table gets more action in season 6 with Dax and Quark playing in 'Who Mourns For Morn?' where Morn fakes his own death to smoke out his former partners in crime, with the intent to have them removed by Quark.
The final time we see this Tongo Wheel is in season 6 where we see O'brien and Bashir learning the game in 'Change Of Heart'
