About Wall Builder
Wall Builder is a free browser construction arcade game where every stage gives you a new wall blueprint. Choose stone or brace blocks, place them in the correct grid cells and complete the structure before the wave timer runs out. Later stages use denser blueprints, tighter time limits and smaller margins for mistakes.
