D70 Test

The domino test was created by English psychologist E. Anstey as a resource to assess general intelligence, or the factor G. It is a non-verbal test focused particularly on abstract reasoning and the ability to understand relationships between different elements. 

Although it employs domino pieces in its questions, it is unrelated to the game. Therefore, being acquainted with it will not represent an advantage for the test-takers other than being familiar with the pieces and with the fact that they are cyclical in the sense that a blank follows a 6.

The original domino test by Anstey had 40 questions in total and is popularly known as the D-48 test. 

The D-70 test was constructed by F. Kowrousky and P. Rennes and follows the same principles as the D-48. It is not intended as a parallel test, but rather a substitute when wanting to confirm the results of the latter or prevent biased results that may arise from the fact that the questions from the D-48 are already widely known.

Despite its name, the D-70 contains 44 questions, which are distributed in series with an increasing level of difficulty. The added complexity throughout the test may stem from symmetry or asymmetry, the type of progression involved (circular, simple, alternating), subtraction, or addition, among others. These rules may appear individually or in combination.

The domino test presented here is adapted from the original D-70, maintaining its structure and principles to ensure a precise correlation of the results.


This D-70 test contains 44 questions in total, divided into series with an increasing level of complexity.

The exercises use domino pieces. Each piece is divided into two and the value on each half can vary from 0 (blank) to 6. In a sequence, the pieces behave cyclically, with the values restarting from zero following a 6: 0-1-2-3-4-5-6-0-1-...

For each question, you will see an empty domino piece within the series. Your goal is to determine the number of dots that should be in each half of the missing piece.


This test is designed as an entertaining and educational tool. The results do not constitute a psychological or psychiatric evaluation of any kind and may not offer an accurate portrait of the mental fitness of the test taker. We do not guarantee the accuracy of the results and these should not be used as an indicator of the capacities of the individual for a specific purpose.

Responses may be recorded and used for research purposes or to be otherwise distributed. All responses are recorded anonymously.
