Kariba is set in Africa where the weather is hot and the water scarce. Animals want to find a waterhole where they can refresh themselves. Of course, every animal wants to be the first to drink and so the elephant chases away the rhino, and the rhino chases away the mouse... But it is well known that elephants are afraid of mice.
Tactical, with an advanced variant that gives players more control over the game, Kariba is both a great filler for gamers and a great family game for non-gamers.
