Dominoes Test

Domino tiles are an ideal way to display numbers due to their symmetry and that most people are familiar with them. They are useful to examine the notion and retention of numbers, as well as the calculation capacity.

The Dominoes test, also called D48, is one of the so-call non-verbal, cross-cultural intelligence test and was created by the English psychologist E. Anstey for exclusive use of the British Navy. It measures the general intelligence ability of subjects according to their logical faculties, and it is based on the deduction of laws or principles of relations.

Although none of the 14 questionnaires presented matches the original test D48, all of them were designed based on this test, increasing the level of complexity in some cases, and all the questions of the original test D48 are randomly within the different questionnaires presented. Each questionnaire consists of 48 questions and should be answered in 36 minutes.

Knowledge of domino game does not give any advantage, just a greater familiarity with the tiles. Despite this test is related to numbers, it does not require mathematical knowledge or special skills. You simply keep in mind that dots are in a cyclic order, so that after the tile with value 6, comes the blank tile.

Questions are generally classified by increasing difficulty and order, and are based on the following principles: symmetry, alternation and simple progression, asymmetry, circular progression, complex progression, combination of previous principles, addition and subtraction, among others.

The principle is to identify one or more laws, keeping in mind that the upper and lower sides of the domino tiles are not always governed by the same laws. As a general rule always use the easiest law or principle.

To answer each problem you must select the orientation in which the tile should appear as well as the dots of each side of the tile, for which you must first identify the principle governing the disposition of the domino tiles.

For example, in the above figure, the upper side of the tiles in each row form a series which increases in 1, while in the lower side of the tiles the same value is repeated, so that the solution is 3|4 (from top to bottom).

If you wish, in the training mode you can see the solution by clicking on the button located on the top right of each question. Sometimes further information about the logic used is provided.

Questionnaires cannot be selected, they will come out continuously and periodically whenever you request a test.
