Financial terms of the deal were not disclosed, but Superbet said the purchase marks the second step in its strategy, having made an initial investment in the platform during its start-up phase in early 2019.
Founded by Olof Orn, Karl Ahlberg and Magnus Petersson, Lucky 7 operates a number of online casino brands across multiple markets in Europe and the Americas.
The business has also applied for licences in other regions, and expects to launch in three new markets within the next 12 months.
“Lucky 7 is an acquisition that complements our current expertise well and further diversifies the SB Group across multiple geographies,” Superbet chief executive Johnny Hartnett said. “Additionally, it significantly boosts our online gaming revenue and brings product and marketing expertise the group will benefit from for years to come.
“I have long been an admirer of Olof and the team from the other businesses they were involved with in the sector. Being able to partner with them to grow together is a great opportunity.”
