A toppling toy unit and construction set enables a plurality of toy units to be assembled into a variety of structures of different configurations. Each toppling toy unit includes end-connectable track-like base sections of different shapes and configurations each with a plurality of dominoes that are pivoted to move from an up position to a down position with each held by a stop that projects up from the base section. When connected end to end when a rear-most domino is toppled the rows of dominoes topple. The base sections are straight, angled, Y-shaped, curved and stair-steps. The base section and stop are a molded plastic unitary construction. A keeper is adapted to be positioned forwardly of the front domino to stop the toppling progression at the forward domino. A pair of posts extended up from the base section are provided for each domino. Each post has an aligned opening for receiving the aligned pivot pins projecting from opposite sides of each domino. The pivot pin slide fits into the slot for assembly and disassembly of the domino to the base section.
