Corrected entry: In the third to last scene we watch young Alan and Sarah carrying a wooden box tied up by rope that contains the Jumanji game. They throw it off a bridge into a river in their hometown. But in the final scene we see that the board game alone is lying in the sand on a beach side in Spain. So the board game managed to break out of the box it was in, and travel all the way to spain. Highly improbable.

Correction: The entire movie is pretty much improbable. The rope could have rotted away. Fishes or wave action could have opened the box. People still throw bottle with messages inside into the oceans to see where they end up. Improbable doesn't always equal impossible.
