Spend 18 sand per round across the three highlighted approach lanes. Stack walls, pack them for extra strength and dig channels. Read the direction and force forecast before sending the wave. Tides erode walls and fill channels, so adapt your defenses between rounds. Survive all three tides with core integrity remaining to win. Three beaches rotate the incoming directions and increase wave force. Undo placements while planning. Click cells to build, or focus the grid and use arrow keys and Enter. Your best surviving core integrity is recorded for each beach.

Play inside the toolbar popup on Firefox desktop 142 or later. The game pauses on loss of focus or when hidden; reopening restores a paused attempt when local saving is available. Progress and records stay on this device. Restart replaces the current attempt; Reset in the guide clears the attempt and records. Private-window progress is temporary for that popup. No accounts, network requests, analytics, remote assets or sound. Reduced motion suppresses decorative dust and moving wave highlights. Android support is not claimed.
