Vidura Invites the Pandavas to a Game of Dice

But Dhritarashtra's attempts to reason with his son were futile. 

"Dissatisfaction is the source of every kind of progress and prosperity, so I prefer to remain dissatisfied," said Duryodhana. "If you wish to see me happy, you will have to fulfil my desire."

Ultimately, Dhritarashtra had to yield to Duryodhana's obstinacy. 

Meanwhile, Yudhishthira saw Vidura's emaciated face and asked, "What's the matter? I hope everything is fine at Hastinapura."

"Yes, son, everything is fine. The king has had an assembly hall built and has invited all of you there to play a game of dice."

Yudhishthira grasped the danger at once.

Vidura added, "Gambling leads only to destruction. I tried to make the king understand, but he didn't listen to me."
