About
A 3D building puzzle on a city construction site. You hold a building plan and a limited load of columns, beams, floor slabs and wall panels on a trailer; two equal pieces weld into a bigger one. Lay the pieces on the plan, press BUILD, and the cranes, the pump and the telehandler put the building up exactly as you laid it. A layout that does not hold sags or falls, the cause is shown at the spot, and your own layout comes back to repair. No clock: every rule is on the plan, so a player who thinks before BUILD knows the result. 100 levels in ten chapters: the yard, the transfer beam, a building on a bank, a building over water, timber, the diagonal brace, odd lots beside a neighbour's building, three storeys, mixed ground and materials, and a whole city block.
