Translation: 
In that match Lord Balarāma first accepted a wager of one hundred coins, then one thousand, then ten thousand. Rukmī won this first round, and the King of Kaliṅga laughed loudly at Lord Balarāma, showing all his teeth. Lord Balarāma could not tolerate this.
Purport: 

Śrīla Viśvanātha Cakravartī explains that the wagers consisted of gold coins. Lord Balarāma inwardly became quite angry when He saw the gross offense of the King of Kaliṅga.
