Fyzuntu is an unusual name, and it is a somewhat unusual dice game. You play against a friend or against an automated opponent. Gameplay fundamentally consists of rolling die onto the table. Depending on your luck you may score highly, or you may roll an unlucky two or five.
You begin with five die each round. When you roll, any die that roll a two or five are removed. Your score is added up from the face value of the remaining die. You continue rolling, following this same pattern, until all your die are removed. Control then hands over to the other player, be it a friend or the computer player. This repeats for an agreed number of rounds.
If you've understood the above, then you know all there is to know about Fyzuntu and how to play it. It brings back friendly memories of playing a dice game with my translator in a bar in China some years ago.
Ultimately, it's not a terribly challenging game. Indeed, there is no vast degree of skill involved - except for when to use the Joker - because the game is ultimately a game of chance. However, for friends who want a simple gamble (with or without actual stakes!) without having to worry about real dice, it serves as fun "pick up and play" entertainment.
The Lite version costs $0.99 from the Apple and Google Play Stores and the full game including the Joker, provision of up to four players and up to eight rounds for $2.29.
