There are a great many forms of divination or scrying, I will list as many as I can quickly think of below with a brief explanation of what they are.
Apple Divination - usually used in foretelling a future partner (love interest). This is most commonly a one time reading.
Astrology - Western, Chinese and Native American Earth Magic are just a few of the forms. Bases on the placement of the sun, moon and various planets at the time of your birth; personality traits, possible mates, careers, lucky numbers, etc as suggested. This form of divination can be used throughout the lifetime of the subject.
Bibliomancy- using a randomly chosen book, opened wherever you think feels right and reading the first passage your eye id drawn to as an answer to a problem or question. This was at one time commonly done using the family bible as the book.
Candle Divination - The use of a burning candle to answer basic questions. How the flame burns (brighter, smaller, sputtering etc) is interpreted for the answers.
Cartomancy - the use of cards either standard playing cards or specifically designed card (ie: Tarot aka Taramancy, Angel, Fairy etc.) are laid out in various patterns and the cards themselves as well as the placement and proximity to one another are `read`to give a look into the future. This type of reading has a limited time frame, however you can have readings done whenever you would like.
Crystalomancy - the use of a crystal ball as a focus for looking into the future. This form is good for answering specific questions or short range looks into the future.
Dark mirror - a specifically made reflective surface designed for looking into the future.
Dice - These can be regular playing dice or marked with sigals and symbols to give readings depending on how they fall. (Astragalomancy - scrying with two dice; Cleromancy - scrying with three dice).
Dowsing - the use of forked twigs (usually willow) or formed copper wires to find water, lost objects etc.
Graphomancy - using hand writing to divine personality traits etc. of the subject. Automatic writing is using a pen in a trance state to get possible messages from `the other side`.
Hydomancy - the use of a bowl of water (or ice), a pond or other still surface of naturally occurring water as a focus for looking into the future. This form is easier with a bowl, but those who use the trickier naturally occurring still water claim the visions are further reaching and more powerful.
Numerology - using the numbers of a date of birth or name (each letter is assigned a numer) to determine the future or answer specific questions..
Palmistry - using the lines, areas, and naturally occurring creases of the palm, fingers and wrist to read the future (or past) of a subject. This form changes with time so having a reading done more than once (over several years) can give you guidance.
Pendulum - the use of a weight, often a crystal or gem but also can be a ring or other piece of jewelry, on a chain or string, used to answer basic questions.
Phrenology - readings of the bumps (usually) on the head of the subject.
Pyromancy - using the flames of a fire (not a candle) to look into the future.
Runes - tiles, stones or sometimes sticks marked with old Norse symbols used to look into the future.
Wax Divination - pouring hot wax into a bowl or container of water and interpreting the shapes found.
