The Combination Game was a style of association football based around teamwork and cooperation. It would gradually favour the passing of the ball between players over individual dribbling skills which had been a notable feature of early Association games. It developed from "scientific" football and is considered to be the predecessor of the modern passing game of football. It originated in Britain and its origins are associated with early clubs: Sheffield FC, The Royal Engineers AFC, Queen's Park FC and Cambridge University AFC. Each of these claimants is supported by retrospective accounts from men who were notable in the early history of football. They are considered below in the order of earliest contemporary evidence of "scientific" football playing styles.

The Royal Engineers Association Football Club is an association football team representing the Corps of Royal Engineers, the 'Sappers', of the British Army and based in Chatham, Kent. In the 1870s, it was one of the strongest sides in English football, winning the FA Cup in 1875 and being Cup finalists in three of the first four seasons. The Engineers were pioneers of the combination game, where teammates passed the ball to each other rather than kicking ahead and charging after the ball. With the rise of professional teams, in 1888 the Engineers joined a newly formed Army Football Association.
