Is there anything official on when a roll should be rerolled (it left the playing area, it's a leaner, etc) or is it a judge call?

Probably it'd be a good thing to go over this ahead of time with my judge, huh? Any suggestions?

Here are some that've come up:

1. A die hits the opponent's shirt and bounces off but lands flat on the board.
2. A die falls on the table next to the board or an adjacent board flat.
3. A die is flat, but on a base.
4. A die slips prematurely.

And of course if it falls on the floor we've been told to reroll both. But sometimes it gets tricky.

Learn to roll your dice with a bit more control, or use a Backgammon cup.
As long as it's still within reach, I'd say to play it with the result
Reroll both.
Reroll both - I'm not a huge rules lawyer, but the rules do say to roll BOTH dice - not "roll one, then the other"

As far as I go, if there is any question, I'll reroll both dice.

I believe they are judge calls, but I usually offer to reroll if anything squirrelly happens.

Thanks. Is that like a Yahtzee cup?

My judge rules that as long as it's flat it counts, so if it bounces off something and lands flat it's good. If it is a "leaner" you re roll that die and if one goes off the table and hits the floor, you re roll both. I hope this helps.

Both dice have to be rolled at the same time. Convention around here seems to be that as long as it's flat, it's good, as long as it stays off the floor. If it's not flat, it only counts if you can balance a die on top without it falling off.

These are the reasons I'd tell a player to re-roll, either dice falls off the table, both dice are not rolled at the same time, one or both dice are setting up on the edge (like a diamond) or if a player rolled while his opponent wasn't looking, his opponent questions it and there where no witnesses of the dice roll.

1. A die hits the opponent's shirt and bounces off but lands flat on the board.

Good

2. A die falls on the table next to the board or an adjacent board flat.

Still good

3. A die is flat, but on a base.

If it is level, still good

4. A die slips prematurely.

I have seen people 'accidentally drop a die, get a one and say 'whoops'. That is not a dice roll issue, that is cheating

The aforementioned die test (place the other die on the questionable die...if it stays it is flat) is the best way

Watch for sliders. Someone with sufficient dexterity can pre-set the dice in their hand and slide them out level (I cannot, I am fumble-fingered)

If there is any dispute, best to re-roll
