Idle Fortress
Defend a snowy fortress from endless monster waves. Build and upgrade five towers, tap to strike, cast meteors, then ascend for crystals that make every new run stronger.
Idle Fortress is an incremental tower defense game set on a snowy mountain pass. Monsters march toward your wall in waves, and your towers fire on their own, so even a few minutes of play makes steady progress. You earn gold from every monster and spend it on five towers: a fast archer tower, a splash-damage snow cannon, a frost spire that slows enemies, a storm coil that chains lightning and a great ballista that pierces the whole lane. Tap monsters yourself for extra strikes and critical hits, and buy stone walls, mending, strike power, bounty and sharp eyes in the fortress tab.
The curve keeps rising. Bosses arrive every ten waves, flying bats ignore your cannons and shamans heal the pack. Reach wave five to unlock the meteor ability and wave twelve for the rally cry that doubles tower speed. If the wall falls, your defenders regroup a few waves back and keep their gold and upgrades. At wave twenty you can ascend: spend everything to gain crystals that boost damage and gold permanently and buy perks such as a head start or an auto striker. Your fortress also earns gold while you are away.
On top of that you collect rank experience and coins for extra perks and banner colours, three goals every day, a daily two-minute siege with its own twist such as swarms or a boss rush, and a streak bonus. Tip: build all five towers before piling levels onto one.
How to play
Tap or click monsters to strike them while your towers fire automatically. Spend gold in the shop to build and upgrade towers and strengthen the wall. Use the meteor and rally abilities when they unlock. If your wall falls you retreat a few waves and can push again. Reach wave 20 and ascend to turn your progress into crystals. Your score is the highest wave you reach.
