While you could'nt or would'nt want to use these for gambling or cheating anyone at a game of craps. I none the less ordered two sets for gambling cheating demos at the game of craps. By betting on hard 4 or 10 & any 7, it's a sure win if any of these are rolled using both magnetic dice. Switching the normal dice for the gaffs of course. Again you would need a pad with 2 magnets hidden underneath to accomplish this trick. Since hard 4 & 10 pay 7 to 1 & any 7 pays 4 to 1, the cheater will always win when placing an even amount of bets on each of the three. Ha - Ha Chump! Have Fun & Happy Holidays to Everyone.

Very well made and undetectable set. If you have the Penguin Hecklau Live, you'll have an excellent routine to work on using the gimmick die.

The cubes are well done, the box is beautiful. Now I am developing a dice tray / something like a dice game /. The performance looks something like this: first, the viewer shuffles the cube in the glass and releases the cube onto the tray. Different numbers are shown on the cube. Then, after replacing the cubes, only the number 2 appears (I get it consistently correctly). But I need it to work with the viewer. So I am experimenting with different magnets. When everything works out, I will completely assemble the entire structure of the tray. Creative process! I am satisfied with the purchase.

The magnets embedded within the one die are strong enough to be used as a forcing die (on of two numbers, depending on the polarity of the external magnet). I'm not sure they're strong enough for most other uses. For the price, this is a good product. But I'll continue looking for a die with a stronger magnet.
