Here is a video of the Open Indoor Cricket Championship which is taking place in Australia. All the state sides from around Australia competed in this form and there was a competition for both men's and women's category.

One can see that the rules of the game for this are quite different. The scoring areas are of course restricted and there are men crowding around the bat even as the batsmen attempts to hit the ball. By the looks of things, it is very difficult to score runs in this format. But, there is one concession for the batsmen. They do not have to run all the way to the bowling crease, but it is merely placed half-way down the wicket.
