Lattice spectroscopy with focus on exotics

Recent lattice QCD results on the hadron spectroscopy with beauty and charm quarks is reviewed. Focus of the review are exotic hadrons, while non-lattice approaches and conventional hadrons are reported as well. We discuss the recently discovered $\Omega_c^*$, charmonia with spin three, $P_c$ pentaquarks, $B_c(2S)$ and $\Lambda_b^*$, the long-standing challenges for theory $Z_c$, $Z_b$ and $X(3872)$, and we review predictions for yet undiscovered states $bb\bar q\bar q$, $\bar bb\bar bb$, highly excited and hybrid $\bar bb$, baryons with bottom quarks and still-missing $B_{s}$ mesons.
