English Simple (Ordinal)
English Simple Gematria (also called English Ordinal) assigns each letter its position in the alphabet: A=1 through Z=26. It is the most widely used English cipher because it is the easiest to calculate by hand and the most intuitive starting point for comparing word values.
English Reverse Ordinal
Reverse Ordinal mirrors Simple Gematria by counting the alphabet backwards: A=26, B=25, down to Z=1. It is used alongside Simple Gematria to check whether a word produces a notable value from either direction.
English Full Reduction
Full Reduction (the same logic used in Pythagorean numerology) reduces every letter to a single digit from 1 to 9 and then repeats the cycle: A=1, B=2 ... I=9, J=1, K=2 ... R=9, S=1 ... Z=8. It compresses the alphabet into a repeating 1-9 pattern rather than a straight 1-26 count.
English Reverse Full Reduction
Reverse Full Reduction applies the same 1-9 repeating reduction as Full Reduction, but starting from the reversed alphabet (Z=1 ... A=26 first, then reduced). It is a less common but frequently cross-checked variant among researchers who track both directions of every cipher.
English Sumerian
English Sumerian Gematria (sometimes just called "Sumerian") multiplies each letter's Simple Gematria value by 6: A=6, B=12, C=18, up to Z=156. The base-6 multiplier is drawn from the sexagesimal (base-60) number system used in ancient Sumer, which is where the cipher takes its name.
Jewish Gematria (English)
Jewish Gematria applies the same ones-tens-hundreds structure used by the Hebrew alphabet (where the first nine letters count by ones, the next nine by tens, and the rest by hundreds) to the 26 English letters: A=10 ... I=90, J=100 ... R=900, S=1000 ... Z=1700. It is not a traditional Hebrew system — it is a modern English-language cipher designed to echo that structure.
