Qubic is a generalization of tic-tac-toe in which players alternately place pieces to get four in a row (rows, columns, pillars, face
diagonals, or space diagonals) on a lattice. There are a total of 76 winning lines.
It was weakly solved by Patashnik (1980), who proved it to be a first player win,
and then strongly solved by Allis *et al. *(1994).
