A minute of arithmetic in your head. Every four correct answers in a row make it harder.
A minute of arithmetic in your head. Every four correct answers in a row make it harder.
The IQ test adds number series, logic, words and shapes. In 10 to 20 minutes you will see which area you are strongest in.
Start the IQ testMental math tests how many simple problems you can solve in one minute. It starts with addition and subtraction up to twenty, and every four correct answers in a row add a level: addition and subtraction up to a hundred, times tables, division without a remainder, a mix of these, and finally a two-digit number times a one-digit number. A mistake does not lower the level, it only resets your streak of correct answers to zero.
You type the answer on the on-screen keypad, or on a computer with the number keys as well. As soon as the answer you typed is right, it is submitted automatically and the next problem comes straight away. If it is wrong, you confirm it with OK or Enter: it counts as a mistake and the game goes on. The result is the number of problems solved correctly in 60 seconds.
It is a short arithmetic game, not a psychological test or an intelligence test. The comparison with other players is a rough guide.
The main number is the count of problems solved correctly in a minute, so higher is better. Mistakes are not subtracted from it, but each one costs time and breaks your streak of correct answers, the streak that moves you up a level. A problem that has not been submitted when the minute ends does not count.
Below the main number you will find your accuracy, that is how many of all your answers were correct, your highest level out of six and the average time per problem for addition, subtraction, multiplication and division. It is calculated from all answered problems of that operation, correct and wrong. Every game gets different problems, so the result can differ by a few problems between two games. The bands in the table are provisional for now, treat them as a rough split, not as a norm.
| problems | ||
|---|---|---|
| Excellent | ≥ 35 | Fast and confident arithmetic. Less than two seconds per problem is enough for you, even when multiplication and division come up. |
| Fast | 25-34 | A brisk pace. About two seconds per problem is enough for you. |
| Average | 15-24 | The middle band. You need around three seconds per problem, or mistakes slow you down. |
| Beginner | < 15 | A slower pace. Mistakes, typing on a phone or playing for the first time may be behind it. |
Typing the answers counts towards the result too. On a computer the number keys are faster than clicking with a mouse, on a phone it depends on how comfortably your thumb reaches the buttons. Tiredness, noise around you and whether it is your first game also play a part: the first time, it takes a moment to get used to a correct answer being submitted automatically.
Every game gets different problems, so the result can differ by a few problems even if you calculate just as fast. A mistake does not lower the level, but it breaks the streak of four correct answers that moves you up a level. Compare mostly your own games on the same device.
There is no published norm for this game. The bands next to the result are a provisional rough split, and the percentile shows a rough comparison with other players on this site once there are enough of them.
The game has six levels: addition and subtraction up to 20, addition and subtraction up to 100, times tables, division without a remainder, a mix of the previous three, and a two-digit number times a one-digit number. Every four correct answers in a row move you up a level. A mistake does not lower the level, it only restarts the streak of correct answers.
You can fix a typo with the Delete button or the Backspace key. A wrong answer is not submitted automatically: you confirm it with OK or Enter, it counts as a mistake and the next problem appears. A mistake is not subtracted from the result, but it costs time and breaks your streak of correct answers.
No. A problem that has not been submitted when the minute ends does not count towards the result, neither as correct nor as a mistake.

Read moreA 130 and a 148 can mean the exact same thing. How IQ bands, percentiles and different scales work, and why your score is a range, not a point.
Read moreThe bands next to your result come from fixed thresholds that are the same for every player. The percentile is calculated from the scores of other players on this site, not from published norms, and it only appears once enough runs have been stored. The typing test has its own comparison for each language version, because the word pools differ. For the other games we pool all languages together.
Measuring conditions differ from person to person: a different mouse, a different screen, a different level of focus. So treat the comparison with others as a rough guide. The most useful number is your own history of recent attempts, which sits right next to the result.
These games are for practice and rough comparison. They are not psychological or medical diagnostics, and the result says nothing about your intelligence or your health.
