3. The Full Frozen Arena
Okay, now we’re talking. The arena is the big one: a huge blue ice floor, high boards made of spruce and quartz, and stands on all four sides so your friends can watch. I built mine with packed ice around the edges and blue ice in the middle, so the centre is the fast lane and the edges are where the beginners wobble. A scoreboard of item frames, banners in two colours, and floodlights on tall posts finish it. It took a week. It was worth every block.
