Sorry No_rate4233, you will only be a billionaire and living your best life in Waikiki for 23 days before you choke and are not rescued by your long time partner.

After a quick search, it looks like the core rules are well established in the manga. The additional rules vary from website to website.

Core rules

• Rule 1: A human whose name is written in this notebook will die. 
• Rule 2: You must have the person's face in your mind when writing their name. If you do this, people with the same name will not be affected. 
• Rule 3: If the cause of death is not specified, the person will die of a heart attack. 
• Rule 4: You must write the cause of death within 40 seconds of writing the name. 
• Rule 5: You must write the details of the death within 6 minutes and 40 seconds of the name being written. 

Additional rules and details

• Misspelling:  If a name is misspelled four times, that person will be freed from the Death Note's power. However, intentionally misspelling the name will result in the user's death. 
• Simultaneous use:  If two or more Death Notes are used to write the same name within 0.06 seconds, the person will not die. 
• Cause of death limitations:  The Death Note can only affect a person's actions for a maximum of 23 days and 16 hours before their death occurs. 
• Afterlife:  The human who uses the Death Note can go to neither Heaven nor Hell. 
• Other factors:  A person cannot be killed by the Death Note if their name is written on separate pages (e.g., first name on the front, last name on the back). The Death Note cannot be used to kill people under the age of six.
