Toy blocks including a hexahedral block, comprising:
- convex projections formed on at least one side;
- and concave grooves configured to be inserted into convex projections on all of the remaining sides through an interference-fit method.
Toy blocks including a cylindrical block comprising a plane-shaped upper side, a bottom side, and sides, comprising:
- convex projections formed on the upper side;
- concave grooves configured to be inserted into convex projections on the bottom side through an interference-fit method;
- and vertical piercing grooves piercing through the middle of the upper side and the bottom side, first horizontal piercing grooves piercing through central parts of the sides, and second horizontal piercing grooves piercing through the central parts of the sides as being vertical to the first horizontal piercing grooves.
