Abstract
Using combinatorics of Young walls, we give a new realization of arbitrary level irreducible highest weight crystals \(\mathcal{B}(\lambda)\) for quantum affine algebras of type \(A_{\,n}^{(1)}\), \(B_n^{(1)}\), \(C_n^{(1)}\), \(A_{\,2n-1}^{(2)}\), \(A_{\,2n}^{(2)}\), and \(D_{n+1}^{(2)}\). The irreducible highest weight crystals are realized as the affine crystals consisting of reduced proper Young walls. The notion of slices and splitting of blocks plays a crucial role in the construction of crystals.
