Grapevine (245)

Instruction:
Draw vines to connect all grape, i.e. grey hexagons to stems, i.e. black circles, with the same symbol. The vine can branch only at triangular cells and can only start in a single direction from a stem. Every white cell must contain part of a vine. Vines must end on a grape, i.e. no dead ends.
