Bookmaker William Hill said it had seen "little evidence" that its business was being affected by the squeeze in consumer conditions.
The group said its total gross win - the amount left by losing punters - rose 9% in the 15 weeks to October 14, with over-the-counter high street business ahead 7% because of favourable sporting results. Hill described the figures as a "good performance", albeit against weak comparatives a year ago.
The company also said it had struck a deal with software firm Playtech to bolster its online gaming and sports betting operation.
Playtech will supply William Hill Online with casino, poker and other gaming software products, in return for a 29% stake in the new operation.
The deal comes a year after William Hill was forced to abandon a long-running upgrade of its internet betting operation - a move which led to a £20.9 million write-down in last year's results.
William Hill chief executive Ralph Topping described the Playtech agreement as a "transformational step" for the company.
He added: "William Hill Online will be the leading European online gaming and sports betting business and the clear online leader amongst UK land based gaming and betting operators."
Mr Topping also expressed his satisfaction with trading in the third quarter of the financial year and said the company remained comfortable with market expectations for the group.
"To date we see little evidence that our business has been impacted by the economic downturn," he said.
Shares responded to the reassuring trading update by opening more than 9% higher.
