Spin Bowling is a rather simple idea compared to say swing bowling. Two basic physics concepts allow spin bowling to happen: inertia and friction.
The basic plan is that the bowler releases the ball such that it spins laterally in a certain direction (toward either the leg or off side: bowler's choice). When the ball actually hits the ground, the inertia of the ball combined with the friction of the pitch turns the spin into a momentary roll. The ball thus converts some of its spin into kinetic energy to move the ball in the direction of the spin. So when it comes back up off the ground upon completion of the bounce, it's actually moving in a different direction.
You can demonstrate this phenomenon for yourself with any simple ball capable of bouncing. Instead of simply dropping it onto a level floor, try dropping it while imparting a spin. When it hits the ground, you'll see the spin influence the direction the ball bounces. Spin bowling is simply a much-more-refined version of this technique.
One rule is that once you start the bowl, you can't stop in the middle of it. Another one is that you have to bowl behind the crease or it will be a no ball.

Pure physics is the realm of the imagination: it is the mathematics of the universe, the theories behind how and why things are the way they are. Applied physics is the science of the real world: generating and distributing energy to our homes and businesses, calculating the effect of friction on machines, analyzing what makes a baseball curve. Often what starts as pure physics finds its way into daily application. For example, the fact that light has a fixed maximum speed is pure physics. Using that knowledge to measure the timing of radio echoes from specific satellites, to determine exactly where on Earth we are (the principle behind GPS), brings that squarely into the realm of applied physics.
