Lattice spectroscopy with focus on exotics

Recent lattice QCD results on the hadron spectroscopy with beauty and charm quarks is reviewed. The focus of the review are exotic hadrons, while non-lattice approaches and conventional hadrons are reported as well. We discuss the recently discovered $Ω_c^*$, a charmonium state with spin three, $P_c$ pentaquarks, $B_c(2S)$ and $Λ_b^*$, 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.
