Dice Roll Simulator

Roll as many dice as you like, with whatever number of sides each one carries, and get instant results alongside a full probability distribution. Tabletop players use it to sanity-check house rules, teachers lean on it to make probability tangible, and developers reach for it when balancing game mechanics, all without scrounging for physical dice. As board games and educational software have grown more intricate through 2026, a clear grasp of dice probabilities has become central to both strategy and learning.

Behind the scenes, the engine walks through every possible outcome for the configuration you choose. It computes the sum of each roll, tallies how many times each total occurs, and divides by the full count of possibilities, which is sides raised to the power of quantity. That gives an exact picture of the discrete distribution and the likelihood attached to every reachable sum.

Adding dice or sides balloons the sample space fast, and the distribution of sums stretches out into the familiar bell shape rather than staying flat. It is tempting to treat every total as equally likely, but with several dice the sums near the average dominate by a wide margin. The figures shown here are the theoretical probabilities; any run of real physical rolls will scatter around them with genuine short-term variance.
