## About Catapult Siege

Line up your catapult, set the arc, and knock down every block of the enemy fortress before you run out of ammunition. Each level builds a castle out of a grid of stone blocks topped with a flag, and the grid grows taller and wider as you advance, so later levels demand more careful aiming and shot management. Three ammunition types are available from the very first shot, switched with the toolbar or the 1/2/3 keys: Rock does one damage, Fire does two and leaves a burn that ticks off a hit point every half-second for a couple of seconds, and Ice does one damage with a frozen recolor.

From level three onward blocks take two hits instead of one. You get 8 + 2 per level shots; clear every block before they're gone or the run ends with 'SIEGE FAILED.' Scoring rewards both hits and demolitions: 25 points for every projectile that connects and 100 for every block destroyed. A dashed trajectory line previews your shot while you aim, levels keep climbing endlessly, and your best score is saved locally.

## How to Play Catapult Siege

Set your angle by dragging up and down or with the Up/Down arrows, dial in power from 10 to 100 with Left/Right, then fire with Space. Pick your ammo with keys 1, 2, or 3: Rock for one damage, Fire for two damage plus a lingering burn, and Ice for one damage with a freeze recolor. Destroy every block in the fortress before your ammo (8 plus 2 per level) runs out to clear the level. Score 25 for each hit and 100 for each block you bring down, then move on to the next, larger castle.

## Controls

Drag vertically anywhere on screen to set the angle, or use Up/Down arrows; adjust power (10 to 100) with the Left/Right arrows. Press Space or release the drag to fire. Switch ammo with the on-screen toolbar or keys 1, 2, and 3. ESC or P pauses. On mobile, drag up and down to aim and tap to fire.

## Catapult Siege Tips & Strategies

1. Use the dashed trajectory preview to dial in your arc before committing a shot, since ammo is limited to 8 plus 2 per level.
2. Lead with Fire on full-health blocks: the two damage plus the burn that ticks over the next couple of seconds can finish a block without a second direct hit.
3. From level three blocks take two hits each, so plan to land two clean shots per block or soften them with Fire first.
4. Only direct hits count, so aim at the blocks themselves rather than the ground nearby.
5. Adjust power with the arrow keys for fine control on the taller, wider castles in later levels.

## Frequently Asked Questions

### What types of ammunition are available?

Three, all available from the start and switched with keys 1, 2, and 3: Rock (one damage), Fire (two damage plus a burn that ticks off a hit point every half-second for about two seconds), and Ice (one damage with a frozen recolor).

### How do I clear a level?

Destroy every block of the fortress before your ammunition runs out. You get 8 shots plus 2 more for each level number; if blocks are still standing when the ammo is gone, the run ends with 'SIEGE FAILED.' Levels keep getting larger with no upgrade system.

### How is my score calculated?

You earn 25 points for every projectile that hits a block and 100 points for every block destroyed. Levels progress endlessly and your best total is saved as your high score.
