It is shown that eigenstates of the quantized simplest closed (elliptic) Nambu -- Goto string, called glueballs, have quantum numbers $I^Gj^{PC}=0^+j^{++}$. Lightest glueballs have spins $j=0,1$ and $2$ and the same mass $(1500\pm20)~MeV$. They correspond to $f_0(1500)$, $f_1(1510)$ and $f_2(1565)$-mesons. Next glueballs have $j=0;1;2;3;4$ and the same mass $(2610\pm20)~MeV$. The slope of glueball Regge trajectories is twice as small as for $q\bar q$-mesons. The intersept of the leading glueball trajectory~--- the pomeron trajectory~--- is $1.07\pm0.03$.
