Online gambling firm 888 said UK first quarter revenues jumped 18% on a like-for-like basis in an "encouraging" start to the year.
The group said UK sales were boosted by recreational customers.
Overall group like-for-like revenues climbed 6% between January and May thanks to more marketing spend and its new Orbit Casino platform, which have helped boost new customer numbers by 26%.
Boss Itai Pazner, said: "888 has enjoyed a solid start to the year with strong momentum in casino and sport across a number of the group's major regulated markets."
in 2017 the company was forced to pay a record penalty of £7.8m after it failed to protect vulnerable customers.
