Everfort: Idle Castle Defense

Your castle fights automatically. Your job is to make it stronger. In Everfort, enemies march toward your castle while its defenses attack on their own. Collect the Gold they drop, choose upgrades, unlock new systems, and build a stronger defense with every run. When your castle falls, the run ends — but your long-term progress continues. DEFEND, UPGRADE, REPEAT • Battle different enemy types, including ranged, tank, support, and Elite units. • Collect Gold and improve damage, health, attack speed, and more during each run. • Stack upgrades and watch your castle become stronger as the waves get tougher. • Earn Skill Points and invest in permanent upgrades for future runs. UNLOCK MORE WAYS TO GROW Progress through the campaign to unlock new systems that change how each run develops. • Choose Prestige bonuses that strengthen future runs. • Unlock defense towers to help protect your castle. • Let sheep collect Gold while you focus on upgrading. • Send miners to gather resources. • Unlock automation to handle more of your economy and upgrades. • Complete missions for additional rewards and long-term progression. BUILD YOUR WAY FORWARD Each run gives you new choices about where to spend your Gold and how to strengthen your castle. Push farther, unlock more systems, and combine permanent progress with powerful upgrades earned during each run. The stronger you become, the tougher the enemy waves get. A CAMPAIGN WITH A GOAL Fight through a 100-stage campaign filled with stronger enemies, new threats, unlocks, and progression milestones. Reach the final stages, clear Stage 100, and keep improving your build through Prestige and permanent upgrades. MADE FOR SHORT SESSIONS Automatic combat keeps the battle moving while your upgrade choices shape each run. Jump in, strengthen your castle, push through a few more waves, and come back later to continue progressing. Offline rewards help you keep moving forward between sessions, while battles themselves happen when you play.
