Your personal map of the world. Pin everywhere you’ve been, everywhere you want to go, the places you’ve lived, and the ones you’d never bother with — across 197 countries and 7,300 cities, zoomable from the whole globe down to a single city. Watch your atlas fill with colour, then share it with a friend: when they open your link, you both instantly see every place you both want to go. A warm, paper-map travel diary and shared bucket-list in one.
by geodude

A world-capitals speed quiz. You’re prompted one country at a time — type its capital and the country fills in with a pin dropped on the real city; hit Reveal if you’re stuck (it won’t count). A spotlight panel zooms to show you where the asked country is while the full map stays put for context. Eight maps (world + every continent), three paces, leaderboards, percentile standings, and a per-answer rarity stat that shows how many other players knew each capital.

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.
by Archvile

A drowned manor, a lamp-spirit, and a window of surface light. You can't move on your own — but you can slip into the sunken furniture and borrow how each piece moves: slide like the chair, step like the clock, vault like the stool, drift like the trunk. Swap from piece to piece to reach the one bright window in each flooded room. A calm, hand-built logic puzzle with a new daily Tide Room.
