Logic Grid

General Overview

About Logic Grid

Logic-grid style tasks ask a person to coordinate several rules at once, eliminate impossible combinations, and hold constraints in mind until a single arrangement remains. The format feels puzzle-like, but the underlying demand is disciplined deduction rather than intuition alone.

This presentation is more modern than some classic subtests, yet it grows out of a long analytical tradition in reasoning tests: not just spotting one rule, but integrating multiple conditions without losing track of what each condition excludes. That makes it attractive when a battery wants to sample controlled, stepwise reasoning instead of only fast pattern recognition.

These tasks are often read alongside other fluid-reasoning measures, but they also lean on attention control and temporary information management. In practice, they help show whether a person is strongest in rapid pattern detection, symbolic sequencing, or slower multi-constraint deduction.

This public version keeps the background and interpretive context visible while the interactive task remains locked.

  • Use logic to determine which shape belongs in the highlighted cell.
  • Time: 30 minutes total for the entire test.
  • The test stops after 3 consecutive errors.
Time Remaining: 30:00
Rule: Each row, column, and region contains each shape exactly once.
