Castle Siege
Arc stones, fire pots and bolts through ten destructible block castles; kill the defenders or smash the gold banner block while enemy archers pick off your five engineers.
The game's own interface may still be in English.
Overview
Castle Siege is an artillery physics game about reducing ten different castles to rubble with a three-piece siege train. Every castle is built from individual blocks with their own hit points, so each stone you land visibly chews the structure apart. You control angle and power, with a dotted trajectory guide showing where the current shot will arc. Three ammunition types force real choices: the stone hits blocks hardest, the fire pot carries a wide anti-crew splash that clears archers off walls, and the bolt flies flat and fast for sniping a single stubborn block or the gold banner block — destroying that banner wins the level outright. The castle shoots back: defender archers loose arrows at your siege line, and every hit can cost one of your five engineers. Lose the whole crew and the siege is over. Later castles add wider fronts, taller walls, roofs that block lobs, inner pillars, and red oil jars that chain-explode for bonus demolition when you crack them.
How to Play
Press Start Game. Arrow Up and Down adjust the launch angle between 15 and 85 degrees, Arrow Left and Right set power, and Space fires. Keys 1, 2, 3 or the buttons switch between stone, fire pot, and bolt. On touch or mouse, simply tap a point on the castle — the game converts your tap into an angle and power and fires immediately, so you can walk shots onto a target. Clear a castle by killing every defender or smashing the gold banner block to advance to the next of ten. P pauses, R restarts the campaign.
Tips & Strategy
Open every castle with fire pots aimed at the wall tops. The pot's splash radius is tuned for crew kills, and every archer you remove is one less arrow per cycle wearing down your engineers while you work. Once the walls are quiet, switch to stone for demolition — it does double the structural damage per shot and its wider blast cracks adjacent blocks. Watch for the red oil jars from castle four onward; a single hit detonates a chain that can gut half a tower, so they are always worth a detour shot. Save bolts for the banner: on roofed castles where lobs cannot enter, a flat bolt through a wall gap is the only reliable banner kill. Do not chase perfect shots — arrows arrive on a timer, so a good-enough shot now beats a perfect shot after two more engineer losses.
What Makes It Distinct
The dual win condition changes the geometry of every puzzle: you are never just throwing rocks, you are choosing between exterminating the crew or engineering one precise structural kill. Combined with return fire that punishes slow play, each castle becomes a timing problem as much as a physics one.

Frequently asked questions
How do I beat a castle with a roof in Castle Siege?
Roofed castles block lobbed shots, so switch to the fast flat bolt and punch through a side wall first, or drop fire pots just short so the wider splash rolls over the wall crest onto the defenders.
What does the gold banner block do?
The gold banner block is the castle's command post. Breaking it wins the level instantly even if defenders survive, which is often faster than clearing every archer on the walls.
Why did my engineers die so fast on later castles?
Later castles field more archers with shorter reload times. Kill wall-top defenders first with fire pots, because every living archer keeps shooting while you line up demolition shots.
