Three drawings, one structure
Top, front and left: three drawings must agree at once. Add blocks, carve away material and watch the silhouettes change in a compact 3D workshop. Matching the drawings is only part of the job. Every block must connect back to the ground through neighboring blocks.
Build it right. Then use less.
The same outlines can hide different structures. Finish within the material budget, then look for blocks whose projections are already covered. Carve through layers and pursue three-star and crown targets with fewer blocks. Undo, redo and progressive hints give you room to experiment.
From gatehouses to vertical cities
Explore 100 campaign levels across 20 chapters, from simple platforms and arches to bridges, towers, courtyards, transport structures and city forms. Rotate the miniature scene or switch to its top, front and left views to uncover the space behind the drawings.
Keep exploring
Seeded random challenges can be reproduced with a challenge code, so you can return to a puzzle or share the same one with someone else. Import, export and play local level packages, too. Campaign progress and drafts are saved locally, ready for your next building session.
