People...do not use dice dares which roll 2 d6 (six-sided dice) and take the sum, as you are favoring one dare over the other.

P(2) = 1/36 (2.8%)
P(3) = 1/18 (5.6%)
P(4) = 1/12 (8.3%)
P(5) = 1/9 (11.1%)
P(6) = 5/36 (13.9%)
P(7) = 1/6 (16.7%)
P(8) = 5/36 (13.9%)
P(9) = 1/9 (11.1%)
P(10) = 1/12 (8.3%)
P(11) = 1/18 (5.6%)
P(12) = 1/36 (2.8%)

Instead, make a 6x6 table.

I'm sorry I have to go off like this...but I feel this needs posting. I can't come up with a table off-hand, but think before posting a die dare which uses multiple dice.

Yes, Luigi is correct in showing the probabilty of each numner is different and seven is the most likely number to come up. It is far less than 50% though. Thats why casino slot machines win on 7-7-7 .

However, it doesn't mean you shouldn't play a two dice dare. You could set-up the game to be more interesting if you keep the probabilities in mind.

It could also be interesting if one player knows this and the other person does not know this.

I didn't suggest not doing a two-die dare. All I said was make 36 dares instead of 11 or 12 to make it work.

I believe that this is already pointed out in the tips and tricks topic at the top of the dice dare board

Yeah, thanks...:wall:

If you can only come up with 12 ideas, here's how you get an even split.

Flip a coin:

Tails: d6
Heads: d6+6

Samples:

Coin == tails, d6 == 3, score == 3
Coin == heads, d6 == 4, score == 10
