A repeatable method and the eight rules that appear most often, with worked examples.
Work in the same order every time: list what changes, name the rule, test it on a second row, then eliminate the options that break it. Most questions combine a few rules: rotation, movement, count, shading, size, overlay, symmetry or alternation. Use ReasonEra to check your reasoning and to learn patterns you miss.
| Rule | What it looks like |
|---|---|
| Rotation | A shape turns by a fixed angle each step |
| Movement | An element shifts along a line or around the edge |
| Count | The number of shapes rises or falls by a fixed amount |
| Shading | Fills cycle in a fixed order, such as white, grey, black |
| Size | Shapes grow or shrink step by step |
| Overlay | Two cells combine to make a third, sometimes with cancellation |
| Symmetry | A cell mirrors another across an axis |
| Alternation | A rule applies on every other step or cell |
Each row turns its shape 90° clockwise per column, so the last cell is the shape turned 180°.
Count rises across rows and fill darkens down columns. Combine them.
In each row the first two cells are laid on top of each other to make the third.
Size grows across rows and the type changes down columns. Both rules must hold.
Try a question yourself first. Then use ReasonEra: Quick Verify shows only the answer so you can find the rule, and Tutor Explanation names every rule. All diagrams on this page are original practice examples written by ReasonEra.
Most employers expect you to complete an assessment on your own. ReasonEra is meant for studying before that day, so use it to understand questions, not to answer a live one.
Practise one rule type at a time, use the same method every time and review the explanation for every question you miss.
Rotation, movement, count, shading, size, overlay, symmetry and alternation, often combined in the same question.
Timing depends on the test. Practise the method until it is quick, and check the timing for your specific test.
Yes. ReasonEra's Tutor Explanation names the rules in each question so you can recognise them next time.
No. They are original practice examples written by ReasonEra.
