Swing of a cricket ball has been a fascinating subject for generations of cricket fans. Principles of boundary layer

separation theory which describes this phenomenon is discussed. Different kinds of swing bowling and the factors

affecting them are analyzed. Hence, optimal conditions for swing bowling are evaluated. It is concluded that a speed of 33 m/s at about 150

seam angle generates maximum swing with a new ball. The seam angle increases as the ball gets older. Equations describing the trajectory of

a cricket ball are also mentioned. Some of the myths surrounding the game like the effect of humidity on swing, control of late swing and ball

tampering are investigated. Finally, some conclusions and further avenues for research are suggested.
