About

Sand Up

Features
Read full description

Sand Up is a relaxing 3D sand sorting puzzle where colorful objects melt away piece by piece. Rotate the object, tap matching color pieces, and turn them into flowing sand. Fill bottles, complete sets of three, and clear each target as the sculpture slowly disappears. Plan your moves carefully. If a color has no matching target, its bottle moves into temporary storage. Keep enough space open, manage your colors, and finish the whole object before your slots fill up. Simple to play, satisfying to watch, and full of colorful sand-clearing fun.
