Game guide
Castle Siege Clash is part construction kit, part physics siege. Each round starts at a blueprint grid where you bolt together a rolling fortress: wooden planks, brick blocks and armed units all draw coins from the same purse. When the layout looks right, hit BATTLE and the game switches into a full physics simulation. Your units fire on their own, projectiles arc across the field, and the enemy castle on the right sheds blocks and collapses piece by piece. Level it to win the stage, pocket the payout and pick a free reward card for the next build.
Actual gameplay


Objective and input
In the build phase, tap a part in the bottom tray, each with its own coin price, then tap a grid cell on your cart to place it; an eraser tool removes parts and refunds them. A short tutorial teaches the golden rule: walls belong beside your units, never on top, or they crush your own crew. Press BATTLE to start the siege. Your fighters aim and shoot automatically while the physics engine chews both structures apart. Destroy the enemy castle to clear the level, claim coins and choose one of three free part cards; if a fight goes badly, retreat or retry with the same layout intact.
Everything runs on single clicks: click a tray part, click a grid cell to place it, click BATTLE to fight. There are no keyboard shortcuts.
Tap a part in the tray, then tap a grid cell on the cart to build it in.
Tap the eraser to remove a placed part and take its cost back.
Tap BATTLE to launch the siege; the combat itself plays out automatically.
What stands out
Snap blocks and units onto a cart grid with per-part coin prices, so every fortress is a budget decision as much as a design.
Battles run on a rigid-body physics engine: blocks weld into structures, break apart under fire and collapse in satisfying chain reactions.
Each cleared level offers a choice of three free part cards, letting you steer the arsenal toward more units or tougher blocks.
Coins from victories feed an upgrade panel where new part types, from stone to cannons and beyond, unlock in sequence.
Useful guidance
The tutorial's advice is real: build walls beside your units, not over them, or the roof will crush your own army.
Cheap wood fills gaps while you save for brick; mixing both stretches an early coin purse.
Losing a fight keeps your layout, so adjust a few cells and send the same fortress straight back in.
Common questions
No aiming is needed. Once you press BATTLE your units fire on their own and the physics decides the rest; your job is the design phase, and you can retreat mid-fight.
You keep the layout you built and can retry the level after tweaking it, so a loss costs nothing but a rematch.
Wins pay coins and offer a pick of three free part cards; coins also fund the upgrade panel, where stronger materials and new unit types unlock over time.
None. The whole game is taps or mouse clicks, from placing parts to starting the battle.
