We study the recurrence and ergodicity for the billiard in infinite polygons, either $Z$-periodic or $Z^2$-periodic. In the $Z$-periodic case the results are quite complete. In the more difficult $Z^2$-periodic case we obtain partial results and discuss suggestive examples. This is joint work with J.P. Conze.
