Be the grumpy old dragon. Word's got out about your hoard, and now they come — knights, scouts, clerics, cloaked sneaks, gold-thieving pack-mules, enraging zealots, shield-bearing bulwarks, banner-waving heralds, leaping vaulters, burrowing tunnellers, the occasional Hero of Legend — delving toward your gold. You can't be bothered to actually fight anyone (so messy), so you arrange the lair against them instead: a slick step here, a fog-venting geode there, a lullaby chime to nap the stubborn knight, a cinderjet that keeps them burning after they pass, a spike-shelf to snap up under a sprinter, a rockfall to pen the whole party. Hold seven winding tunnels — some folding back on themselves so a single trap bites twice — each with its own path, its own delvers, and a new tool to earn. Waves now arrive in surges with a lull between, so drop a fresh trap mid-fight before the heavy push lands. Then dive into the endless Deep Delve. A daily Raid + a leaderboard of the realm's grumpiest dragons.
