Is it possible somewhat inexpensively to set up sensors for this game? Answered

I've got the lighting down... now I just need a way to activate it.  It's the classic ladder-toss, golfball horseshoes, what ever you want to call it... You throw a string with a ball on each end at a 3 rung stand and try to wrap your strings around the rungs.  I'm running a strip of LED's through each tier and drilling small holes so you can see the light emitting but am trying to figure a way to have the LED's blink for a few seconds when you score.  Thought about sensors in the balls, but sometimes one ball will be closer to a lower rung than to the rung you've actually scored on so was thinking maybe some kind of pressure sensor on each bar?  This seems too complicated to me, but perhaps one of you knows a way?

I don't have an arduino and am on a bit of a low budget, but any ideas are welcome even if out of my budget I'll have something to think about on down the road.

Idea: very rigid stand, looser mounted rungs. When you score the rungs wobble a bit due to the balls attaching - you might get a switch out of that.

E.g. Have the rungs mounted on springs which are one electrical contact, make your other electrical contact very close to the springs, but not quite touching.
Elastic might be easier, nail in the end of the rung for one contact.

That's actually a wonderful idea... much simpler than the only idea I'd come up with (laser aligned with a photo-sensor on the other side of each rung that the string would block when wrapped around.) Thanks for the insight.
