Editor's Notes

You have 60 seconds on a sunny beach to stack the tallest, most decorated sandcastle you can

What players will love

Spend most of your 60 seconds tapping Build, since each block is worth 10 points and stacking is the fastest way to score
Add decorations toward the end for extra points, but they are worth 5 each, less than a block
The HUD counts down the seconds, so pace your taps to keep stacking until the very end
Block widths are random, so tap rapidly rather than fussing over a perfectly even tower

About Sandcastle Builder

You have 60 seconds on a sunny beach to stack the tallest, most decorated sandcastle you can. Tap to drop sand blocks, which auto-stack one row higher each time, or switch to Decorate mode to scatter beach emojis on top. When the timer runs out, your final score is the block count times 10 plus the decoration count times 5. A quick, breezy creative challenge against the clock.

How to Play Sandcastle Builder

A 60-second timer starts as soon as you begin. Two tools sit at the top: Build and Decorate. In Build mode, each tap drops a sand block of random width that auto-stacks one row higher than the last, so taller stacks come from more taps. Switch to Decorate to place a random beach emoji (flag, seashell, star, banner, or wave) wherever you tap. When the timer hits zero the game ends and your score is locked in as block count times 10 plus decoration count times 5.

Controls

Tap to drop a sand block, which auto-stacks at the tapped x-position. Tap the Build / Decorate buttons at the top to switch tools. On desktop, click to place blocks and decorations.

Frequently Asked Questions

What happens when the timer runs out?

The game jumps to the Game Over screen and your final score is calculated from what you built: block count times 10 plus decoration count times 5.

How is my score worked out?

It is the number of sand blocks you stacked multiplied by 10, plus the number of decorations you placed multiplied by 5. During play the HUD shows your block count as 'Height'.
