PRACTICE / NO SCORE OR SAVED RECORD

Try an idea.
See how it works.

Two original Ownfacet examples to explore combining and removing visual elements. Try a construction, ask for a hint, or reveal the explanation at any time.

This learning space uses no scored OMIB items, reads no saved responses, and changes no assessment records. Familiarity with the format can still affect a later attempt.

Example

Construct the missing cell.

Practice matrix with the bottom-right cell missing. — Check the relationship across each row, then test it against the last row.

Your construction

No elements selected.

Select the corner triangles

These examples use only the four corner triangles. Select every triangle that belongs in the missing cell.

Reveal the worked construction

Try the same rule on every row. A plausible pattern must account for the visible cells, not just the missing one. These are explanations of two examples, rather than a universal solution method.

Keep practice in perspective.

There is no score, timer, certificate, or ability estimate here. The assessment uses a separate, fixed set of 22 tasks and does not reveal its keys. Repeating those tasks is not evidence of a change in intelligence.
