you a couple of ways, you can do that. The first and easiest way, is just to buy a pair

of trick dice from a local craft store. The best place is probably a magic store, because

they usually carry trick dice, where you can actually roll the dice, and end up rolling

sevens more often than not. A couple of other ways you can do that, is you can actually

drill in to the pips on the dice, using a drill. Don't hold the dice in your hand, put

it in a vise. Drill down, and you could actually add some lead weights into the dice, so it

would be more likely to land on that side. Another thing you could do, is you could actually

take the dice, put it in an oven, find the optimum temperature to do so, and the dice

will actually melt, and some of the material will actually pool up on the bottom, thus,

making that side of the die, heavier. Again, giving it more of a probability to land on

that side. Another thing you can do, is you can learn, and this is actually, technically

not illegal at the casinos, is you can learn how to hold the dice in a certain way, so

that when you roll, and you flick it in a certain fashion, it will come up the number

you want more often than not. This takes hours and hours of practice. Although not technically

illegal, if a casino catches you doing it, they will ask you to step away from the table,

hopefully with lots of money. My name is Dean Hale, and I just taught you, how to cheat

at dice. Good luck.
