Hold the castle gate against side assaults, siege engines, and sudden repair shortages.
Castle Siege Defense uses the tower defense loop as a siege story. The enemy can pressure more than one approach, and the gate health represents the castle's last line. During the first minute, the attackers are slow enough that basic towers hold comfortably. Later events add siege engines, side gates, and resource shortages that make a simple front-door layout collapse.
Build on wall pads by tapping or using the selector. Upgrade with U when a tower needs to break armor. Towers splash, which helps against ladder rushes, but siege engines force you to keep damage concentrated near the longest approach.
You score for destroyed attackers, preserved gate health, and time survived. Each run rolls a different pressure order except in debug mode. Hardcore can arrive before or after the exact ten-minute mark, but once it does, side assaults and armored pushes become the baseline rather than a surprise.
The best opening covers the front lane and one side angle. Do not overbuild the entrance before seeing the first event. If the side gate opens, add coverage near the merge. If stone shortage appears, stop buying new towers and upgrade the one already doing the most work.
Mobile players should watch the event text more than the enemy count. The castle looks stable early by design, then the siege starts behaving like an actual siege with multiple simultaneous problems. In this version, the events to respect most are siege engine, ladder rush, side gate. If one of them is less than half a minute away, delay cosmetic expansion and keep enough resource for one decisive build or upgrade.
