Wallyball is all about the right amount of randomness plus a lot of teamwork and a lot of mental calculations (that feel great when they work out, and feel silly when they don’t!). The basic premise is that it is volleyball, with a volleyball-sized raquetball, in a raquetball court, with a volleyball net. Yeah, crazy, I know. The walls are legal, even on serves, as long as you don’t hit the ceiling or back wall (or two walls) on the over.
I’ve been playing it off and on with a great, fluid crew from Wizards Saturdays for almost two years. It’s a fun group activity, even though the activity level is much lower than volleyball. Usually this is because the ball is hitting a lot of walls / you can use the walls to propel your shot into position – as opposed to normal volleyball, where it’s all about position and shot strength / type. We’ve had more than a fair share of injuries, because like raquetball, the ball can move in unexpected and dangerous ways.
Overall, it’s great fun, and I recommend it to everyone. Nothing quite compares (in my team physical activity experience) to the coordination of a volleyball bump-set-serve with the walls to add power… and then continuing the volley with an amazing dig and off-the-wall return. It’s not really volleyball, but I think I love it more for that, having been crushed in volleyball too many times. 😉
