Siftwend

Siftwend is a falling-sand puzzle in a glass jar you can turn upside down. Paint sand, water, oil, wood, fire, ice, plants, lava, steam and stone, and watch them pile, flow, burn, boil and grow. One button flips gravity for the whole jar: sand and water fall to the lid, flames and steam rise towards the floor. Play 20 short goal jars with a small palette and three-star ink budgets, a daily jar that is the same for everyone, and a free sandbox that saves itself. It plays in the browser with a mouse, touch or keyboard, on phones too.
