Gender Reveal Balloons & Darts! My wife and I made a balloon board using black opaque balloons, and filled one with blue confetti. Then we let friends and family throw darts until they popped the balloon with the confetti. Everyone loved it! *To make sure they game wasn't over too quickly, I actually filled the board with empty balloons. I waited until all were popped to bring out the one with the confetti in it (and we let our moms throw the final darts). It helped build some fun tension.
