Lottery and scratch-off game sales increased by 6.5 percent over previous estimates as gambling revenues rose $148.8 million from estimates made in February, a panel of state economists determined Thursday, reports the News Service of Florida. Going forward, panelists said it was a good bet collections would continue to outpace estimates as the Lottery rolls out a series of scratch off games for the upcoming holidays. Scratch-off sales continue to remain stronger than expected, with collections rising $85 million from previous estimates. Powerball collections were also higher than expected, climbing 18.6 percent, or $41.6 million, from February estimates. Powerball figures are expected to change again in January as the multi-state game makes a number of changes including higher ticket prices and better odds and higher payouts.
