These dice use clever mathematics to achieve something remarkable. Imagine the situation... You and 3 friends need to decide who goes first, second, third and fourth in a board game. So you decide to roll some dice. Highest number first...

These 6 sided dice aren't regular cubes. The're oddly wonky. But amazingly they are totally fair. That's because they are isohedral, meaning every face can be mapped onto every other face through a symmetry of the object. These objects have...

These 5 dice are unusual! They are constructed from polyhedra you don't normally see in the dice world. Take for example... The d12. Normally constructed from a regular dodecahedron, but here for your mathematical pleasure we have the rhombic dodecahedron. Unlike the platonic dodecahedron,...

The world's first mass produced 120 sided dice. This 50mm disdyakis triacontahedron has elongated triangle faces and is isohedral. They are perfectly numerically balanced, with the same sums for numbers around vertices of the same type. Available in red, white, blue,...

We only sell 5 dice in this set... becasue that's how many regular convex polyhedron there are. We'd include the Kepler-Poinsot polyhedra but where would be put the numbers? This one's for the purists - get you dice the way Plato...

Loads of games require you to roll two regular dice (or 2d6 is gaming slang) and when you do, not all scores are equally likely. 12s and 2s are rare while 7s are common. See the graph above. But remarkably...

Many games involve rolling two dice and adding the numbers. These dice have the numbers 1, 3, 4, 5, 6, 8 and 1, 2, 2, 3, 3, 4 - but yet give the same results and probabilities as two normal...

Most 20-sided dice have the decency to arrange the numbers so that opposite faces always add to 21. But they do not make sure the numbers are evenly distributed around each vertex. This "numerically balanced" d20 has six vertices which...

Behold the Numerically Balanced D30! The latest dice from The Dice Lab, makers of the Numerically Balanced D20. This is a 30-sided die where not only do opposite faces always add to 31, but also numbers are evenly distributed around...

Have you ever had a lovely pair of D10 dice only to lose one of them? No? Well this product solves a problem you never had by placing one dice inside the other. That way you'll only ever lose them both at the...

Have you ever had a lovely pair of D12 dice only to lose one of them? No? Well this product solves a problem you never had by placing one dice inside the other. That way you'll only ever lose them both at the...

Rock Paper Scissors is the classic non transitive game of chance,or skill if you know a bit of psychology. But if you want to remove the psychological element AND introduce some extra complexity, you need the Rock Paper Scissors Lizard Spock...

This is the set of 5 Non Transitive Grime Dice with a bulk order discount. You get a lesson plan and other resources with your order (you don't get the bag!). You can also download the resources for free from the brilliant Think...

Rolling three separate dice is so much effort. Shake and roll this single medium-sized cube and it'll throw three identical dice for you in one go, saving time and energy. Also, you can use it to set people maths puzzles...

In this set of dice, green tends to beat red, red tends to beat yellow, yellow tends to beat blue, and blue tends to beat purple. So you might think green is the best dice and purple is the worst. But here's the...
