Sandcastle Siege

Strategy · 8 beaches plus Endless · Phone and desktop

A parade of crabs marches up from the sea toward your sandcastle, and every one that reaches it knocks off a flag. Tap the sand pads beside the path to build defences: a water-pistol kid for quick shots, a bucket catapult that splashes groups, a seaweed net that slows them down and a lighthouse beam that reaches far and hits seagulls. Spend shells to upgrade, send waves early for a bonus, and hold out through 8 beaches with tougher critters, two paths and a King Crab, then try Endless mode.

How to play

  • Tap a sand pad and pick a tower to build.
  • Tap a tower to upgrade or sell it.
  • Earn shells by stopping crabs and finishing waves.
  • Keep at least one flag on your castle.
