About this game

The night comes for the ember.
You are the keeper who keeps it burning.
Close the app — the watch continues. Open it again, and morning brings a real harvest.

EmberKeeper is an offline-first idle tower defense set in a walled village that lives only as long as its ember stays lit. Place your companions along the road the night creatures march down, spend your skills at the right moment, and hold the line wave after wave.

WHY THIS ONE
- Real offline progress, honestly counted. Your watch keeps earning while the app is closed, and what you collect is an honest settlement of that time at your current strength — no fake timers, no "simulated" numbers. Buy an upgrade tonight and tomorrow morning's harvest is already bigger.
- A proper tower defense underneath. Twenty creatures a wave in rotating species, a magic-touched enemy mid-stage, a boss on every fiftieth wave, and a village boss that stands off the road buffing its own army until you can answer it.
- A fresh build every run. Between waves you draft one of three cards, and your keeper unlocks four skills as you go — Emberfall, Thornbind, Tidecaller and Halving Light. No two nights have to be built the same way.
- A cozy-spooky night you'll actually want to look at. Warm ember-glow over a deep blue-violet night, painterly art, never a dark or scary screen to squint at.

OUR FAIRNESS PROMISE
Ads are 100% optional and rewarded — watch one for a bonus, or never watch one at all. There are no in-app purchases: everything in the shop is bought with gems you earn by playing. No per-unit paywall, no subscription, no loot-box odds — companions are earned through play, never gambled for.

WEBSITE & COUPONS
New free coupon codes for gems land regularly at algolenslab.com/emberkeeper/coupons — no account needed, just check the page and redeem in-game.

THE LOOP
Play an active watch: place, upgrade, draft, cast, push the wave counter higher. Fifty waves make a stage, and every stage ends in a raid that stands between you and the road onward. Then just close the app. Check back in a minute or a day later — either way, the owl is settling your harvest, and there's a workshop, a codex, and a roster waiting for what you bring home.

This is an idle game built for people who have a life outside their phone: a real offline tower defense with an honest overnight harvest, not another app demanding to stay open.

Free to play. Optional rewarded ads. No in-app purchases. No paywalls on power.
Idle tower defense: keep the ember burning offline, wake to a real harvest.
