**BINARY DIGITS**** - To commit to memory as many digits - randomly consisting of 2 different digits of 0 and 1 - as possible from 200 lines of 30-digit numbers in required memorization time.**

(There can be more than one attempt at this category with different sets of random numbers each time if time permits.)

There are different versions of “Binary Digits” as follows;

Event |
Memorization Time |
Recall Time |
---|---|---|

Binary Digits (1 minute) | 1 minutes | 3 minutes |

Binary Digits (5 minutes) | 5 minutes | 15 minutes |

Binary Digits (15 minutes) | 15 minutes | 30 minutes |

Binary Digits (30 minutes) | 30 minutes | 60 minutes |

**Software:** MEMORIAD™ Competition Software

**Memorizing**

- In this category, Memoriad™ Software generates 200 lines of 30-digit numbers that consist of different combinations of digits 0 and 1 (e.g. 1100101001010...) and show them in sequence on the screen of each competitor’s computer.
- The computer generated numbers are presented in five pages on the screen and each page covers 25 lines of 30 digits.
- Each 30-digit number is written next to each line number (as in; Line
**21**:**1011101101000...**). - All the competitors are supposed to memorize the same set of digits.
- The competitors try to commit as many lines of numbers as possible to memory from the list of 200 lines of 30-digit numbers in the given memorizing time.
- Competitor doesn’t have to use the full memorization time given. When a competitor has reaches his/her memorizing limit or another reason, he/she can stop his/her memorizing stage and stay quietly until the recalling stage starts.
- As soon as the memorizing time is over, software closes the memorization stage screen.

**Recalling**

- As soon as closing the memorization screen, MEMORIAD™ Software opens up the recall screen to each competitor so that they can enter their answers.
- The competitors have to enter their answers on that screen in the given recalling time.
- The competitors must enter their recalled 30-digit numbers next to their corresponding line numbers.
- Those lines whose corresponding 30-digit numbers are not recalled should be left blank.
- The competitors do not have to use the full recall time. Whenever they stop their recalling stage, they can see their score on their own result screen.
- When the recalling time ends, MEMORIAD™ Software closes the recall screen automatically and shows the result screen of the competitor.
- In the result screen the software shows the errors of the competitor for his own evaluation. If the competitor does not close the result screen, it is closed by the software automatically at the end of given 5 minutes evaluation time.

**Scoring**

- "30" points are given for each complete row of 30-digit number recalled correctly.
- "15" points are given for each row of 30-digit number recalled with only one digit mistake.
- For every complete row of 30-digit number that has two or more mistakes (including missing digits) 0 point is given.
- For the last row recalled only, if the last row is incomplete (e.g. only first 23 numbers written down) and all the digits written down are correct, then a partial point is given (23 in this example).
- If the last row is not complete and there is only one digit mistake in this row, then the points are given as the half of the digit numbers recalled (e.g. 23/2=12 points).
- If the last row is not complete and there is more then one digit mistake in this row, then “0” point is given for the last row.
- In this category there can be more than one attempt. If more than one attempt are made, primarily the best score obtained from all attempts will count.
- In case of a tie, the second best scores of the competitors that are not equal are considered. If the tie persists, the rates of correctness in the answers for which the competitors get "0" points are compared. The percentage of non-point correct answers should be more than 70% of the total non-point answers.The competitor who has fewer mistakes is the winner.
- The competitor who gets the top score wins the event.
