    Welcome to Dog Might’s short series of articles on Wooden Dice. We are extremely pumped to bring these to the gaming world! So, our the first topic: How do these dice feel in your hand compared to plastic polys. How to Measure the Weight of a Die At Dog Might we play a lot of games, which means we roll a lot of dice. We understand that there’s something special about having a favorite pair of dice in hand. When you shake them in your hand, you’re experiencing a sensation that has been shared across time and cultures from all over the globe. All that history and potential energy becomes keyed up as you prepare to roll, and just like the millions of humans that rolled before you, these dice become something incredibly special to you. Because of this, how dice feel in your hand is very important. It’s the same reason my War Hammer is a little heavier than most. During the testing for Wooden Dice, our Underdogs (a group of 15 of the most incredible people we have ever been associated with), told us that hand feel was one of the most important factors in choosing the right set of dice. They, like a lot of people, assumed that wooden dice would be substantially lighter than plastic dice. After tons of research and testing we found they were half right. Some of the more common, domestic woods are a bit lighter than plastic polymers, but a lot of the exotic hard woods we use often are very close to the weight of plastics and many are heavier. Since we began creating dice, we have tried to focus on woods that weigh the same or heavier than their plastic counterparts. To demonstrate how our dice feel compared to plastic dice, we have created a “Weight Meter” which delineates how our wooden dice compare, by species, to plastics. A set of 7 standard polys weighs in at 1.0 to 1.1 ounces. We have used that measure as the baseline for our “Weight Meter”. The lightest dice that we have made, Maple, come in at 0.7 oz and the heaviest, the Ebonies, come in around 1.4 oz. For instance, African Blackwood is the 3rd heaviest wood in the world after Itin and Black Ironwood. Keep in mind, though, that woods vary from tree to tree and board to board. So, one set of dice made from Blackwood could be heavier than another of the same species. Because of this fact, we weigh every set of dice then post the appropriate Weight Meter. If weight is an important factor in your dice selection choose a set that comes in at Medium, Heavy, or Very Heavy. These will feel just like your set of plastics or heavier. Little known fact: Heavy D took his name due to his love of heavy dice. I hope this new Weight Meter helps when choosing your perfect set of dice.

    We are Viking Lumberjacks, not scientists. But, our Head of Ops, Zoe once was. We asked her to test our Wooden Dice using that strange, wonderful, unknowable thing they call science. So, onto her results. To test the balance of our dice, we took a Chacate Preto D20 (similar weight to your typical plastic D20) and rolled it 1000 times. We also rolled a D20 made by one of the most popular plastic dice brands on the market 1000 times. You can see the roll results below in bar graph format. You may be tempted to draw some conclusions from this graph, but let's get into the nitty gritty. First, some basic statistics: our Chacate Preto D20 had an average roll of 10.427 with a standard deviation of 5.6684, the plastic die had an average roll of 10.205 with a standard deviation of 5.5559. Already, these numbers appear like they won't have any statistically significant difference between them. But let's test that to be sure. So, second, a quick, simple test: a two-tailed t-test gives us a t value of 0.37645. This is higher than your standard alpha cutoff, 0.05, so this tells us that there is no statistically significant difference between their averages, as we expected. But let's go deeper... What about the rolls within each die? Does the wood or plastic die roll certain numbers more or less than any others? Performing an ANOVA, we get a p value of 0.3721. Again, this is higher than 0.05, so there is no significant difference across the roll results. There is variance, but no number appears more or less than another in a significant manner. Finally, what about between one another? Is the roll distribution in the wooden die different from the plastic? Nope – and this is the most definitive result. With a p value greater than 0.9999 (from another facet of the ANOVA), there is no statistically significant difference between the two die's results. From the ANOVA, we do also get coefficients of variation. The wooden die's was 17.99% and the plastic die's was 21.97%. As we already stated, there's no statistically significant difference between these two variations. It could be argued that the wooden die has less variation – the numbers are more evenly distributed in their chances – but it's insignificant. DISCLAIMER: These are just two die. It is entirely possible that we could grab another plastic die and another wooden die and the results would be different (although it's pretty likely that the differences would still be insignificant). Unbalanced die can be produced, but to thoroughly test the likelihood of those existing, you would need to roll multiple, different die of the same manufacturer 1000 times (preferably on different surfaces, by different people). At the end of the day, though, our dice are virtually the same as your most popular plastic brands out there (balance-wise) and you shouldn't need to worry about your rolls!
