▶ Play nowA cozy creature-collector with real depth underneath.
Mythlings: the Hollow is a base-building creature collector set in a keep ringed by living fog. You start with nothing but a guide and a single egg. Crack it open, and out comes your first Mythling — one of hundreds of possible combinations of five archetypes and six rarities, each with its own look, stats, and temperament.
From there the Hollow grows. You clear the fog to claim land, raise buildings that work while you're away, put your Mythlings to jobs, breed your best pairs in the hope of something rarer, and take your champions into the Trials of the Mist or the arena against other real keepers. It's the kind of game you can dip into for two minutes or lose an afternoon in.
Every system feeds the next — collect, grow, and prove your keep.
Find eggs in the fog, hatch them in the Cracking, and fill a living dex of Mythlings across five archetypes and six rarities.
Pair your best Mythlings to pass down stats, archetypes, and rare traits — and chase the jump to the next rarity tier.
Push back the fog, place farms, mines, and nests, and upgrade every building through eight levels as your keep climbs.
Combat is a fast, skill-based lane duel — read the telegraph, block, and time your attacks. Gear matters, but so do you.
Climb a hundred hand-tuned Trials of the Mist toward the Sovereign, then push into the endless depths for bragging rights.
Battle real keepers' teams in the arena, climb the leaderboards, and chase a fresh monthly pass of rewards.
You'll be raising your first Mythling within a minute.
Yes. The whole game is free to play. There are optional gem packs and a Mythlings+ pass for players who want to support the game and skip a few timers, but nothing is locked behind a paywall and there is no bought power.
No. Just open the game and play — your progress saves to your device automatically. When you're ready, grab your recovery code from the Profile screen to carry your Hollow to another phone or bring it back if you clear your browser.
Any modern browser on a phone, tablet, or computer. It also installs to your home screen like an app, and an Android version is on the way.
Your Hollow saves locally and, online, backs itself up to the cloud. Add it to your home screen and write down your recovery code and you're covered — those two steps keep a save safe across weeks away and new devices.
Battles are real-time lane duels, not auto-battlers. A telegraph warns you before every enemy hit — block it, then strike back. Your Mythling's stats and totems matter, but timing and reads decide the close fights.

The Hollow updates constantly. Recent highlights — the full history lives on the devlog:
Prefer to read before you play? The site carries the whole Handbook.
The Keeper's Guide covers every system, with deep dives on battles, breeding, buildings, jobs, the economy, and the Trials, Arena, and Endless Mist. The Mythlings introduces the creatures themselves, one page per archetype — Brawler, Ranger, Mystic, Support, and Scavenger. And the devlog keeps the honest record of what shipped and when.
Crack your first egg and see what the fog has been hiding.
