Roof Drop

Tap to drop the next roof tile onto a tiny house silhouette; align angle and material to keep stacking until the dream cottage becomes a mansion.

Core mechanic

A roof tile falls and you tap to release it; the closer it lands to the silhouette outline, the higher the score and the fancier the upgrade.

Controls

Tap to drop the falling tile; swipe sideways to nudge.

Theme

Tiny-house roof stacker borrowing the home-builder clicker mood.

Why now

Poki's trending list shows a flood of 'Builder' titles (Stack City, Survival Builder, Roller Coaster Builder 2), confirming room for fresh one-thumb building loops.

Signals · overall 5/10
Hook
5/10

Tap-to-drop tile stacking is a familiar core (Drop Stack, Stack Ball, Perfect Slices); the silhouette-accuracy + cottage-to-mansion upgrade arc adds light novelty but not a new verb.

Virality
4/10

Slow-build stacking games stream/clip less well than high-contrast fail or transformation loops; misses are mildly funny but not inherently shareable.Drop Stack — canonical tile-drop reference showing the mechanic is widely cloned.

Simplicity
8/10

One-thumb tap + optional swipe is among the cheapest control schemes to prototype; no assets beyond tiles + silhouette.
