Josh did a good job summarizing the tent features, but of course they have lots of fun subtleties that he didn't mention... just to tease a few...
Quoted from rosh:
Ring Toss is about hitting the targets on the Oktober and fest target banks, alternating one side from the other
Hitting X-in-a-row lit targets gives progressively higher scores. If you're skilled (or lucky) enough to sweep the entire lit OKTOBER bank in one shot (7-in-a-row), the points will be raining down. Completing either the OKTOBER or FEST bank gives a bonus, and completing both banks gives mongo bonus.
Preferably in sequential combos, which become more and more valuable. It's very satisfying (and valuable) to hit a 5 or 6 or 7 way combo on the Roller Coaster ramp.
Yes, it's a switch frenzy... but you increase the frenzy value for every *distinct* switch you hit on the playfield. Think you'll just rip the spinner like in many frenzies? That's OK, but you'd be much better off shooting a bunch of OKTOBER, FEST, or PROST targets, *then* rip the spinner. And as long as you're at it, if you shoot the spinner via the right orbit shot, try using the top lanes MagNab to catch the ball up there, and further increase the frenzy value on that TAP lane and then the pop bumpers.
That's just a few of the hidden features... I'm not spilling the beans on all of 'em, don't want to take away all the joy of discovery.
And of course, each tent's scoring is multiplied if you have the stein associated with that tent.... and you can stack several of those steins if you really want to try blowing out the scoring for a tent.
