The game board is a 4×4 grid. This can be a simple printed sheet of paper.

The game pieces are elements of a logic set. The characteristic of logic sets is that each piece is unique (no two pieces are identical), and each piece is defined by the same set of properties. For Same Four, a set of 16 pieces is needed. These 16 pieces should be characterized by 4 properties, each having two possible values. An example of four properties could be: shape (circle or square), colour (red or blue), size (small or large), and fill (solid or hollow).

Based on this, the 16 pieces needed are:

Children can also create their own sets for the game. They may choose any theme, but the 16 pieces must meet the criteria described above.

For example:

Flowers – colour (yellow or blue), stem (tilted left or right), petals (4-petaled or 3-petaled), leaves (has leaves or no leaves)

Bottles (real ones) – material (glass or plastic), shape (stout or elongated), cap (with or without), label (with or without)
