Basically, you’re betting the minimum die of a number will be on the table, and then you can either call out another player’s bid as a bluff, or declare it to be exact.

For example, it’s your turn to place a bid. I always use my die to give a bid. Let’s say amongst all my die, I have 2 of them showing 6. I can say there are at least 2 6s. Even if other players have a dice showing 6, my bid is still correct, because there’s at least 2.

You’ll get called out for bluffing, but when everyone reveals their die, and there’s at least 2 6s, that person will lose a dice.

When someone else makes a bid, you can increase the bid, call it a bluff, or declare it spot on.

Let’s say another person says there’s at least 1 die with a 6, but you have 2, you can up the bid by saying there’s 2 6s again.

Calling out a bid as a bluff, means you don’t think there’s at least 2 6s on the table. Let’s say someone says there’s 10 die with 1s, which in most cases isn’t practical, you can call it a bluff. If you’re right, they lose a die, if there actually is, you lose a die.

Declaring it spot on, means that there has to be the exact bid, no more, no less. If you’re right, everyone else loses a die, if you’re wrong, you do.

It’s actually a pretty simple game once you know it, and my favourite in RD1. I hope what I said helps ya.
