The game is based upon the classic dice game YATZY. Everything that exists in yatzy also exists in Megajatsy. The difference is that Megajatsy has one more dice and you can save throws that are not used. When six dices are used, it is possible to have new combinations like 3 pairs, cottage, tower, etc.
The goal in this game is to get as much poinnts as possible. To get points you must throw the dices until you get a combination. You can hold the value of any dice(s) between the throws. You should also try to get as high value as possible of the dices in the combination, this because the sum of the dice is what you get in points for it.
When the game starts all players have three throws. If you dont use all three then the unused throws are saved until next turn. You can save a lot of throws until the last turns.
