Cidle OnlineCidle Online

Cidle Online is a free idle strategy game where your castle keeps working while you're away. Queue up upgrades, send soldiers across a shared world map, and come back to full storehouses, finished jobs and, now and then, a raid report from a neighbor.

Play in two-minute bursts between other things, or settle in for an evening of boss hunts. Either way, your castle is a little bigger every time you come back.

• Idle at heart: every job runs in real time, whether you are online or not
  
• One shared world: every player's castle sits on the same map
  
• Bosses and rivals: dragons, krakens, a server-wide Titan and real neighbors to raid
  
• Long-term progression: 10 castle stages, prestige, up to 5 bases, relics and themes
  

Start with a small keep and grow it through ten visible stages into a towering citadel. Gather wood, stone, food, coal, sand and iron ore, refine them into planks, iron and glass, and spend it all on upgrades that train more soldiers, store more loot and make every job faster.

When one castle is not enough, found up to five bases on the map. Max one out and you can prestige it for another, stronger climb.


Every player lives on the same persistent map, and it is full of places worth a detour: mines to explore, villages to raid, ruins, lost cities, shipwrecks and fishing spots. Tap a forest or a stone field for a quick handful of materials, or claim a Lost City for gold and the odd chest. A Wandering Shop and a Gambler roam the land, and loot pouches turn up where you least expect them.


Snakes and spiders, trolls and minotaurs guard their hoards on land, while krakens and giant crabs lurk offshore. Dragon lairs are the long haul: a 16-hour expedition, and the dragon may strike back at your castle while your army is away.

Every so often a Titan rises, and players across the server send soldiers to bring it down together.


Your neighbors are real players. Raid their bases for resources, and build up your defenses so they think twice about raiding yours. The leaderboard shows who rules the realm.


Towers pay out gold for as long as you hold them, up to five at a time. Claim a dormant one with a relic fragment, and the relic you spend decides how it looks. Taking a tower from another player is a four-hour raid, and a freshly taken tower is safe for two hours before anyone can raid it back. Towers reset every week, so there is always a fresh fight.


Work through a 65-quest campaign and a fresh set of daily quests, and earn titles along the way. Wear the one you are proudest of: it shows above your name on the map for everyone to see. There are 100 Steam achievements to unlock too.


Bosses drop relic fragments. Piece ten together and you have a relic, the key to a new castle theme. A theme changes more than the look: Clockwork Tower speeds up every job, Dragon's Lair shortens dragon hunts, Treasure Hold improves your loot, Dark Sanctum sends your raids out faster, and Iron Bastion hardens your defenses.

Idle, or hands-on

Every job runs on a real-time timer. Let it tick while you do something else, use a speedup, or pick Manual mode when you send soldiers out and cut the timer down yourself with one of six quick reflex minigames. The better you play, the more time you save.

Free to play

Cidle Online costs nothing to play. An optional shop sells small packs of gold, gems, speedups and relic fragment chests, each with a weekly limit, plus a Supporter pack that turns your name green. The shop does not sell relics on their own; you earn those in play. Everything in the shop except the Supporter badge can also be earned in play, and Manual mode lets you cut expedition timers without spending a thing.
