Rule 1: The human whose name is written in this note shall die.[1] Rule 2: This note will not take effect unless the writer has the person's face in their mind when writing his or her name.[2][3] Rule 3: The Death Note will not [ever affect a victim] whose name has been [misspelled four times].[3] Rule 7: The Death Note will not take effect if a victim's name is written on several different pages. However, the front and back of a page is considered to be one page. For example, the Death Note will still take effect if the victim's last name is written on the front page and first name on the back. Rule 8: If the cause of death is written within 40 seconds of the victim's name, it will happen. Rule 9: If the cause of death is not specified, the person will die of a heart attack. Rule 10: After writing the cause of death, the details of death should be entered within the next 6 minutes and 40 seconds. Rule 11: If the time of death is specified within 40 seconds of writing the cause of death as a heart attack, the time of death can be manipulated and can go into effect within 40 seconds after writing the name. Rule 12: The conditions of death will not be realized unless they are physically possible for that human or could be reasonably assumed to be carried out by that human. Rule 13: Since the limitations applying to the conditions of a death are unknown to the Shinigami, Death Note owner's must find out on their own.[4][5] Rule 14: You may write the cause and/or details of death prior to filling in the name of the individual. Be sure to insert the name in front of the cause of death. You have about 19 days according to the human calendar to fill in a name.[3][4][5] Rule 15: Suicide is a universally valid cause of death as all humans are thought to possess the potential to commit suicide. It is, therefore, something that may be reasonably assumed of an individual.[4][5] Rule 16: Whether the cause of the individual's death is either suicide or an accident, if it would lead to the death of more than the intended victim, the person will simply die of a heart attack. This is to ensure that other lives are not impacted.[5] Rule 19: … default to a heart attack.[6] Rule 20: A subject can be influenced for no more than two days leading up to his death.[6] Rule 21: If you write "dies from disease" and specify which [disease but not a time of death, if the progression] of the disease takes more [than X days, the X-]Day rule will not take effect and the [human will] die at an appropriate time depending on [the disease.] However, rewriting the cause and/or [details of] death must be done within 6 minutes and 40 seconds; you cannot change the victim's time of death, however soon it may be.[6][3][5] Rule 24: (This is a duplicate of Rule 21.)[5] Rule 25: In order for the Death Note to take effect the victim's name must be written on one page; however, the cause and conditions of death may be entered on other pages. This will work as long as the person who writes in the Death Note keeps the specific victim's name in mind when writing the cause and conditions of death.[5] Rule 26: If the cause and conditions of death are written in before the victim's name is, multiple names can be written as long as they are entered within 40 seconds and the cause and conditions of death are not impossible. In the [event that the cause of death is possible but the conditions are not, only the cause of death will take effect for that victim. If both the cause and the conditions are impossible, that victim will die of a heart attack.][5] Rule 27: … conditions are not possible will simply die of a heart attack.[7] Rule 28: Each death must be physically possible.[7][8] Rule 29: A human death caused by the Death Note …[7] Rule 31: If the victim's name has been entered and the Death Note is destroyed while the cause of death is being written, the victim will be killed by a heart attack 40 seconds after writing the name. If the victim's name and cause of death have already been written, then the victim will be killed within 6 minutes and 40 seconds via the stated cause of death if it is possible within that period of time. Otherwise, the victim will die by heart attack.[9][10] Rule 32: If you wish to change anything written in the Death Note within 6 minutes and 40 seconds after you wrote it, you must first rule out the characters you want to erase with two straight lines. The time and conditions of death can be changed, but once the victim's name has been written, the individual's death can never be averted.[10] Rule 33: It is useless to try to erase names written in the Death Note with erasers or to white them out.[10]
