How to play Sandcastle
- Drag a piece from the tray onto the beach (or tap a piece, then tap a column). Sand stacks where you drop it, but loose sand slumps off a column more than 4 above its neighbours.
- When the tide meter fills, a wave rolls in from the sea and erodes sand from the bottom up. Your tallest tower must reach the goal line or you lose a heart.
- Packed walls soak up wave power, moats (shovel) swallow water and stop crabs, wet buckets harden a whole column. Shells and flags that survive pay bonus points.
- Tap seagulls before they steal decorations and flip crabs before they pinch your walls. Every 5th tide is a rogue wave. Coins buy stronger sand, bigger buckets and bonus coins.
