Move your mouse or touch horizontally to position the top dropper. Click, tap, or press Space to drop the sand stream straight down into the container.

When matching sand tiers touch, they flash with a bright gleam and fuse into the next higher tier, evaporating volume to create extra room!

If the sand pile rises above the dotted red Danger Line at the top, an emergency 10-second timer starts. If you don't trigger a merge to lower the sand level before the timer reaches zero, it's Game Over!

Yes! Add '?bare=1' or '?stream=true' to the URL to run in clean transparent streamer mode.
