The Oliver Twins are two British brothers, Philip and Andrew Oliver known for their work as video game developers. They began to professionally develop computer games while they were still at school, contributing their first type-in game to a magazine in 1983. They worked with publishers Codemasters for a number of years following their first collaboration Super Robin Hood, most notably creating the Dizzy series of games. At one point during the 1980s it was reported that 7% of all UK games sales were attributable to the Oliver Twins. In 1990 they founded Interactive Studios which later became Blitz Games Studios.
