Yatzius Rex is a fun “Yahtzee” simulator that actually takes the classic dice game a step further. To start with you can play in the classic Yahtzee mode which allows each player to take one turn which is up to three rolls of the dice. There are five dice in all and you're looking to get a wide range of different results in order to fill out your entire score card. You can build up points by getting the maximum possible score for each section.
