Intouch Games currently has more than 100 workers at its site in Stourbridge but wants to expand to a new base in Halesowen.
Bosses have already taken on 50 staff in recent months as business booms.
Managing director Simon Wilson said: "We're very excited about our move to Halesowen, and it represents a massive step forward in the development of Intouch Games.
"Intouch Games are proud to be leading the way for tech companies in the West Midlands and we're constantly looking to hire diligent, hard-working, talented individuals who can help the company fulfil its true potential."
It is set to move to new offices at Fountain House in Great Cornbow in either October or November.
A floor of 15,000 sq ft has been let to Intouch, currently based in Penn House, Bradley Road.
Six-floor Fountain House has just been sold and the floor let to Intouch is to be refurbished.
Owner and operator of mFortune and Pocketwin mobile casino, Intouch was recently named in the LSE's annual 1,000 Companies to Inspire Britain list.
The company will be recruiting staff with a range of skills including computer programming, marketing, graphic design and call centre operators.
It is looking for 20 'high-end' programmers, 15 graphic designers and 25 call centre agents.
Intouch Games also expects to take an additional floor in the near future, doubling its commitment to Fountain House.
It currently has its team spread between offices in Stourbridge, Bucharest and Budapest.
The relocation to Halesowen has been prompted by the rapid development of the business over the last 12 months.
There are two other existing tenants at Fountain House in Structural UK and Third Financial Software, occupying just over 10,000 sq ft between them.
With Intouch it will now have more than a third of its 68,000 sq ft space let.
KWB, which has been retained to market the office space in Halesowen, will now focus on the forecasted remaining 30,000 sq ft.
The refurbishment of the offices, will include upgrading of windows, air-conditioning and common areas.
Malcolm Jones, of KWB, said: "The vast majority of available office space in the area is not of a condition that makes it attractive enough to potential occupiers to secure a letting.
"The work being carried out at Fountain House will provide Halesowen and the surrounding area with viable office space, and we expect to receive a significant number of enquiries regarding the property."
Nic Burton, of Ruskin Properties, said: "Fountain House is a great addition to our growing portfolio.
"It's a substantial body of offices and a significant property within the local market.
"We are delighted to be able to bring to market high grade offices in Halesowen.
"The quality of most stock currently available in the area is falling short of modern occupier requirements and expectations.
He added: "Fountain House will offer a rare opportunity to potential occupiers – office space in Halesowen that can provide them with a fresh, welcoming, up-to-date place to work that is mechanically and electrically reliable."
