Sandcastle Siege

Your kingdom is made of sand. The sea has other plans. Build a sandcastle defense, release the tide and watch the water find every gap. Sandcastle Siege combines touch-friendly construction, grid-based water flow and crab-fighting towers in a colorful offline strategy game. BUILD YOUR WAY Drag rows of sand walls, brace them, dig moats, raise shell barriers and place palisades. Use sandball turrets and shell cannons against crabs; artificial reefs slow the flow. Repair between waves, upgrade defenses and reclaim part of your materials when demolishing. THE BEACH CHANGES Protect your castle through 25 campaign missions on Sunny Beach, Rocky Coast and Storm Island. Read the tide forecast, plan for cross currents and storms, and face red, fast, armored and giant crabs. Erosion opens real passages through damaged walls. KEEP YOUR KINGDOM GROWING Earn treasury shells on first-time mission victories. Improve six permanent abilities and collect four castle styles using in-game rewards. Unlock Endless after mission 3 and experiment with unlimited resources in Sandbox after mission 5.
