At last count there are currently 6 major variations of the theory. See table below:

A Brief Table of String Theories

 

Type Dimensions Details
Bosonic
26
Only bosons, no fermions means only forces, no matter, Major flaw: a particle with imaginary mass, called the tachyon
I
10
Supersymmetry between forces and matter, with both open and closed strings, no tachyon
IIA 10 Supersymmetry between forces and matter,
IIB 10 Supersymmetry between forces and matter, with closed strings only
HO 10 Supersymmetry between forces and matter, with closed strings only
HE 10 Supersymmetry between forces and matter, with closed strings only.
