Grain Drain: Sand Sort Puzzle

Every tray is packed with colorful sand. Can you drain every last grain?

Grain Drain is a satisfying sand puzzle about one hungry hole. Drag it across the tray and the sand crumbles in. Bring it to the gate of the same color and watch it pour out. Empty the tray and find the right order when the sand tries to trip you up.

DRAG, SUCK, POUR
• One finger to play: drag the hole around the tray.
• Sand crumbles and falls into the hole as you drive through it.
• Stop at a gate of the same color and the sand pours in.
• Fill every gate and the level is done.

A REAL SAND PUZZLE
• The hole only holds so much, so think about what to pick up first.
• Take the wrong color too early and you can get stuck.
• Some gates are doors: fill one and the way behind it opens.
• Queue doors make you fill one color, then the next.
• Tall sand holds twice as much. Lifts carry you between two floors.
• Hard levels are marked, so you know when to slow down.

100 LEVELS TO CLEAR
• Easy trays to warm up, tricky routes to finish.
• Sand pictures to eat through: a crown, a key, a rocket, a cat, a watermelon and more.
• Earn up to three stars: the fewer trips, the better.

FOUR BOOSTERS
• Whirl: tap a color and its sand lifts over the walls into the hole.
• Drill: punch a gap through a thin wall.
• Long Pour: everything you hold blasts into its gates, wherever they are.
• Deep Hole: the hole holds more for this try.

COINS AND GIFTS
