Abstract: A method and device for generating hot sheets for lottery numbers based upon previously drawn numbers and astronomical data. A player selects at least one number for input. The input number is then searched for in a database containing historical data of at least one comparison lottery including the number and date of previous draws. It is then determined when the number selected by the user was previously drawn in the comparison lottery by accessing the comparison lottery database. A second database, which is also accessible by the device, which may be a part of the first database, contains data regarding the timing of certain astronomical events, such as planet aspects, planet ingress, moon ingress, and the phases and eclipses of the moon. Time gaps between the time of the previous drawings of the number selected by the player is determined, such as by using the dates immediately before and after the dates the number previously fell.
