Koplow GamesCharacter Builder Loaded Dice

Excellent novelty item. Good fun with the kids, or with an unsuspecting DM, but not recommended for even Bar Dice- They are obviously not balanced.

Now that I have received them I still don't know why I bought them. Maybe I can switch them in a casino dice game and win big. Maybe I can cheat my friends. Maybe I can cheat relatives. Maybe I can predict the outcome of a throw. Once. It would be safe to say that it's nearly impossible to throw anything but a six.Do I like them? Yes. I gave them a five. Why do I like them? Don't get me started.I don't know why I purchased these dice. Maybe I can use them in Vegas to win big. Maybe I can cheat my friends and relatives. Maybe I can predict the total of a throw once. Maybe I can ring them in street dice games and get shot.

TL;DR: Rolls a 6 around 75% of the time for an average value of 5.33. You can probably get away with rolling these dice 6 times (once for each ability score) if you get lucky with how the dice land on the surface and your fellow players have a negative wisdom modifier. But otherwise I would say it'll be hard to roll more than 2-3 times without raising suspicion, especially if you get unlucky with how the dice interacts with the surface and if you are playing with people proficient in perception. Naturally, how much your fellow players trust you in the first place is a huge factor in determining if someone notices you're cheating as well.Rolled these dice a bit over 3,400 times into a rectangular, felt-lined dice box and got the follow results:1 - 1.06%2 - 7.57%3 - 5.11%4 - 5.28%5 - 5.63%6 - 75.35%With these numbers, the average value for a single one of these dice is roughly 5.33 as opposed to a 3.5 from a normal six-sided dice. Basically, this dice is 4.5 times as likely to roll a 6 than a normal dice.Naturally, these skewed odds come at a price -- that is, the dice are probably too obvious to use with other people. I think there are 3 main problems with the dice when it comes to being too obvious:1) The dice have a tendency to wobble/dance a lot across the ground due to the uneven weight of the dice before they finally settle on a side. Normal dice occasionally also wobble depending on the roll, but these dice might wobble weirdly every 2 or 3 rolls. It's generally not a huge problem if you only are rolling these a few times, but the more you roll with these, the more wobbling sticks out. I don't think this problem alone gives the dice away, but I think that any half-observant person would combine this issue with the fact that you're rolling a 6 around 75% of the time and guess that something is up with the dice.2) This is kind of an extension of #1, but sometimes it looks like the dice is going to land on a number that isn't 6 and then suddenly flips itself to land on 6. It happens a bit less often than #1, and often when it happens, it's not that obvious. But sometimes when it happens, it looks extremely abnormal, as if there's a magnet pulling a specific side of the dice towards the bottom. I'd say if you run into a particularly bad case of this, someone vaguely observant might determine that these are weighted.3) These dice feel and look odd compared to most dice. These dice are heavy -- which isn't conclusive of weighted dice by itself -- and I think 99% of people would not be able to tell if the dice is unevenly weighted just by holding it. The dice use pips to number each side instead of the actual numbers found on most D&D dice. They're also slightly on the large side. Again, none of these are deal breakers by themselves. The biggest issue with them is if someone else touches these dice. If the dice have any number except 6 facing upwards, then even slight touches can cause the dice to jump to 6. Vice versa, if the dice is already on 6, then you can feel how it resists going to any other number when you touch it (although this is not as much of a big deal as the other way around). Lastly, you can still see the drill marks on the "1" side of the dice where the original part was drilled out and replaced with something heavier -- this is probably a red flag to most people.In conclusion, I won't be using these in any of my campaigns. Although I might be able to get away with it if I'm just using them to roll for stats, I think the risk is not worth the reward. That being said, the dice seem to be of decent quality and it does do its job as advertised -- just perhaps a little too well.Random thoughts after rolling these dice 3,400 times:-I think you can somewhat mitigate the problems with these dice through practice. I'm not sure, but it feels like certain ways of rolling cause less wobbling/dancing and issues where the dice just "flips" to a 6. Things like releasing the dice extremely close to the surface instead of dropping them from higher up seem to help.-Bouncing the dice off of the wall of the dice box seemed to result in a lot more 6's. I guess the bounce gave more chances for the uneven weight to do its magic.-Some other reviewers suggested mixing these dice with regular dice. I agree and would specifically recommend dice that also use pips as opposed to numbers. If you can get dice with similar color, size, and pip markings, that would be ideal.

We play a dice game with friends and this was a great prank we all had a good laugh with these

My son bought these as a prank gift for his DND group, and they were very loved.

I got these as a prop to teach probability. They are way too obvious, so math isn't necessary. I wish they were only slightly more likely to land on six than something else, but the description is fairly accurate. It's hard not to get at least one six, and almost as difficult not to get two. Whether 70% is accurate for the rate of three sixes, I'm not sure--I didn't do the calculations--but I'd guess it's at least that.

Great dice - Very obvious it’s loaded though.These dice always roll a 6. No matter what.I spun it the dice in a circle when it was a 1 and it somehow ended up being a 6.You will not manage to be discreet with these dice.Still freaking awesome

These dice are the well-crafted. They are wooden and larger than the typical d6 you get in a standard polyhedral set so you may want to seek out similar dice if you want to go unnoticed. Picking them up it's very obviously weighted. They are heavier and feel as though the weight is imbalanced. They do roll all 6's more often than not, so if you want to go unnoticed I'd recommend mixing them with other dice to merely nudge things your way, or only using all three sparingly. It will rapidly become obvious that these are loaded if you use them consistently together as any "good" roll lands them 5-6 almost every time and any experienced DM will know something is up.
