Green_Hilltop: No, which one? Sounds fun but I prefer to play honestly, but I'm interested how can you do it. :)
Tarnicus: I was almost always the dungeon/game master and never used it in a game. Cheating in games is pointless to me :) It involves spinning the die in a certain way. I'll see if there are any videos of the technique. I've never searched before as the Internet didn't exist when I used to play :)
You know how you can spin a coin so it ends up looking like a sphere? Well it is similar to that. So for a 20-sided die, you would get one of the 5 numbers showing on top. This means that you can narrow the odds significantly. With enough practise, it is possible to learn to almost get the exact number but it is harder on D20s. The same technique can be used for all of them, even a D4!
The only game I remember cheating in was the card game 500, and that was when my father taught me how to cheat shuffle. The only person I cheated against was my mother as it annoyed her to be beaten by a child :P
Oh right! So you basically throw it and make it land on one number where it spins in a sphere. But wouldn't people notice that?
