Logic Grid Practice

Free · no sign-up · unlimited new questions

A logic grid is a 4×4 grid of figures. Each property — such as the shape or the direction of the pointer — appears exactly once in every row and every column, just like in Sudoku. One cell is missing, and you work out which figure belongs there.

How it works

• Easy: two properties (shape and pointer), four answers.
• Medium: fill is added as well, six answers.
• Hard: four properties including an inner element, eight answers — and one or two further cells are hidden.

Tips

• Check each property separately: which shape is missing in the row? Which in the column?
• With hidden cells, think crosswise — the missing values follow from the other rows and columns.

Relevance for IQ and Mensa tests

Sudoku-style questions train systematic elimination, a skill many logic tests assess.

Frequently asked questions

Is it like Sudoku?

The principle is similar: every value appears exactly once per row and column. Instead of numbers, there are figures with several properties.

How many cells are missing?

You are always looking for one cell. On the hard level, one or two other cells are hidden as well.
