A turn-based tower tycoon where the building has to actually stand up, stack tenants too far over the edge and the overhang shears clean off.
Build your tower upward by dropping tenant blocks floor by floor. But the structure obeys real support rules: overhanging too far makes a section shear away, and piling too much load on a column makes it buckle. Three structural failures and the tower collapses, so you're balancing height and score against the physics holding it all up.
Stacking blocks upward until the structure fails is an old arcade shape; what is original here is that the failure modes are the real ones.
Overhang too far and a section shears away — a cantilever has a limit — and pile too much load on a column and it buckles, which is a sudden failure rather than a gradual one.
Buckling is the interesting half, because it is not about weight so much as slenderness: a column can be strong enough and still fail. That makes height and score genuinely opposed, since the fastest way up is also the way that loads a single line of supports.
Tenant Stack is an original free browser game that blends tower-building tycoon management with a structural-support simulation, where the constant threat of shear and buckle makes every floor a real decision.
