Toy construction kit comprises at least one first, second, third and fourth building block (1-4). All four building blocks have a base surface (11, 21, 31, 41) provided at least with a first and a second continuous groove (111, 211, 311, 411, 112, 212, 312, 412) that can be connected to the first and second grooves of another building block. The base surfaces of the first, second, third and fourth building blocks have a height ratio of 2:2:2:4, a width ratio of 1:1:1:1, and a depth ratio (length ratio) of 1:2:4:2. Preferred Features: The third building block is a cylinder with an end side forming a base surface whose height and width correspond to the diameter of the cylinder.
