Sandcastle

About

Sandcastle is a real-time strategy game centered around a single cannon defending a beachside town. Players aim and fire to sink waves of enemy ships before they reach the sandcastle. Each round ramps up the threat with faster or more heavily armored vessels. Upgrades between battles let you tweak projectile power and reload speed. The interface is stripped-down to basics, no base building or resource gathering. Just you, the cannon, and the relentless advance of enemy fleets. The game’s simplicity is its hook. With no frills or distractions, it boils RTS gameplay down to a tense bullet-dodging loop. Armor Games polished the controls to feel responsive and satisfying. Browser-based play keeps it accessible for quick sessions. Though released over a decade ago, its core loop still holds up for players looking for straightforward strategic shooting.
