For this round there are 6 dice. In this example there is a 6(a dice you want to get) and a one (a dice you need to get in order to qualify). Here there are 4 low value dice and two dice I want to keep. So I take the two I want and then re-roll the others.
With the dice rerolled, and there is a 4 (a die you need to qualify). This is the only notable die in the bunch so re-roll the rest.
Here you have a 5 here which is a good die so take that and re-roll the rest.
There is a 6 GREAT! Take that and since a three is in the lower half re-roll that.
Tough Luck. A one, you have no choice but to accept it here and hope for the best.
-Grab the One and Four as fast as you can.
-Always take any 6s you see, except if you are still looking for a 1 or 4.
-You are best off with only 5s and 6s in your final 4 dice. If you can help it don
Good guide, however, since you have to fill the spot in order to continue and they can get low rolls, it is best to roll all the dice over again. Example:
I roll 1 5 5 2 3 6, here you you place the 1 and roll the remaining 5 over again as it gives you a better chance to roll a 4 than if you were to keep the 6 and roll 4 dice alone. Since you can fill the spots with anything it is best to do this so you have a slightly better chance to qualify in more games.
