🏰 Sandcastle builder

On the beach there is a plot of smooth sand, and the sandcastle builder turns it into a sculpting table. Children shape the sand with their finger or mouse, add castle parts, and when they press Done the castle stays standing on the beach — still there the next time they visit.

Shaping the sand

Pick a tool below the plot, then drag on the sand. Pile heaps sand up, carve digs it away, and smooth rounds off rough slopes. Because the sand behaves like a surface rather than blocks, children can make hills, ditches and ramps of any shape, and fix mistakes by simply piling or smoothing again.

Castle parts

Once the ground is shaped, stamp on castle parts with a single tap: towers, walls, gates, stairs and a moat, and finally a flag on top. Parts sit on whatever sand is under them, so a tower on a hill really does stand taller.

Not sure where to start?

Three templates lay down a ground plan to build on: the Keep (a classic castle), the Fort (a bigger one) and the Mound (a little hill to decorate). Younger children often start from a template and add towers; older ones like to begin from flat sand.
