Playtech is splashing out £23m to buy online games developer Ash Gaming, seriously enriching the London-based founder.
Chris Ash founded the business, which operates from Southwark, in 2002.
The money will be paid out over three years, with management and another unnamed investor sharing some of the spoils.
An initial £15.5m will be paid out straight away. Ash's best-known titles are Amazon Wild and Madness House of Fun. In the year to April, it had revenues of £4.2m, with a profit of £2.6m.
