Play Online Sandcastle Showdown
In this game you defend a sandcastle from waves of invaders. You man a cannon and fire at pirate ships and angry soldiers. Enemies move across the shore. They collide with your walls. You keep your fortress intact and fight back.
You can pick from several cannon models. One fires shots in rapid bursts. Another reaches distant targets on the horizon. A heavy gun sends a single blast and clears large groups.
Upgrades pack more punch and cut reload time. Points arrive after each wave. Those points unlock stronger barrels. You swap your cannon and meet each new threat. The fortress stays intact through stronger defenses.
