Yatzy Online is a free dice game, where players compete to score the most points by rolling dice and using the dice’s number to score. Each player has their own turn, and when a player rolls a 6, they score a point. The goal is to score the most points in each of your turns.
The game can be played online or offline. You can play against your Facebook friends (requires Facebook login), or against opponents that are sitting next to you (pass & play).
An upgrade would allow you to enjoy personal statistics, a training mode, an assortment of colorful themes, zero ads, and full screen support.
