Logical reasoning test
Combine clues to reach a certain conclusion, and work out a hidden rule from a few examples. No words, no trivia: just logic.

What a logical reasoning test measures
Logical reasoning covers two related skills. Deduction is combining facts to reach a conclusion that must be true. Induction is spotting a general rule from a handful of examples and applying it to a new case. Both are core parts of fluid intelligence and of everyday problem solving, from debugging code to planning a budget.
Balance-scale puzzles
Each balanced scale tells you that both sides weigh the same. Combine the scales to find how much each shape weighs, then answer how many of one shape balance the question scale. Easy questions need a single step; hard ones need several scales combined, just like solving a small system of equations, but with pictures instead of letters.
Heavier or lighter
Each tilted scale shows which of two shapes is heavier. No single scale gives the answer: link them into one chain from heaviest to lightest, then pick the shape at the position the question asks for. Longer chains, shown in a scrambled order, need more links held in mind at once.
Hidden transformation rules
You see grids before and after the same hidden rule, such as a quarter turn, a mirror, swapping filled and empty squares, shifting everything one step or letting filled squares fall to the bottom. Harder questions chain two or three steps. Work out the rule from the examples, then apply it to the new grid.
Tips
- For scales, start with the scale with the fewest shapes and write the weights down as you find them.
- Check that the answer is counted in the right shape: the question asks how many of one specific shape balance it.
- For tilted scales, find the shape that is never on the lighter side: that is the heaviest, and the chain starts there.
- For transformation rules, track one distinctive filled square through every example.
- A rule must work for every example pair, not just the first one.
Frequently asked questions
Do I need math for the logical reasoning section?
Only simple addition. The balance scales need careful reasoning, not formulas, and the rule puzzles need no numbers at all.
