Five mobile gaming companies have made it into this year's O2/Real Business Top 50 to Watch in Mobile list.
Highest up is I-Play, the only one to appear in the top ten with a placement at No. 7. With revenues of GBP 11.9 million it's Britain's largest mobile games firm, according to Real Business.
At No. 17 it's Player X, while in 23rd place Tag Games is flying the flag for Scotland. Tag is one of two Dundee-based mobile games developers to make it into the chart, with Dynamo Games sneaking in at No. 47.
Telcogames is in 35th place while Babel Media, which offers a range of outsourcing services to the mobile gaming industry, is at No. 46.
All hardware, software and service companies working in the UK's mobile sector are eligible to appear in the Real Business Top 50. Entries are judged by a panel of experts from the industry and media who draw up the list of the companies they believe show the most promise.
Tag Mobile MD Paul Farley said the company was "thrilled" to have made the list, adding, "It's an honour to be on the same list as many of the large, established companies... We'd also like to congratulate Dynamo for being nearly as good as us."
Dynamo boss Brian McNicoll commented, "To be chosen alongside some of the largest and most high profile mobile companies in the country is a great achievement. Dynamo has worked hard to establish a very credible and professional reputation."
