I think I remember voting Wild 1. When I was younger I always liked exploding lemmings to see if they can get down to the bottom towards the exit. It's very random where the bombers end up without blockers, and that's what made it so addicting.
I voted both Havoc 10 and Havoc 14 in that last round. They're both great concepts for 1-minute challenges, and two very different ones at that.
