About

Spaghetti

Features
Read full description

Spaghetti Marshmallow is a physics tower-building puzzle where dry spaghetti are your struts and marshmallows are the glue. Drag to draw a strand of spaghetti. Tap to drop a marshmallow that grips every strut it touches. Stack, brace, and triangulate your way up to the goal rings — but watch out: the wind never stops blowing, and a top-heavy or poorly-braced tower will sway, buckle, and collapse in a very satisfying heap. It's secretly a structural-engineering sandbox. Real truss rules apply: • Triangulate to resist racking — a plain square folds flat, one diagonal makes it rigid. • Every joint needs a load path down to a solid foundation. • Cantilevers snap at the root, right where the torque piles up. Hold a marshmallow on every target ring at the same time for 3 seconds and the level is yours. FEATURES • Intuitive draw-and-tap building — easy to pick up, tricky to master • Real physics: elastic spaghetti, plastic marshmallow grips, honest collapses • A full campaign that ramps from gentle breezes to howling gales • Hazards to build around: hungry frogs, fire pits, falling rocks, spinning windmills, moving obstacles, aliens and more • Resource limits that force clever, efficient designs • A built-in level creator — design your own levels and share them with friends by a simple code • A fresh Weekly Challenge for everyone • Thirteen hand-drawn scenes: day, night, beach, kitchen, space, volcano, castle, circus and more • Free to play, no ads Build tall. Brace smart. Beat the wind.
