Basic Instructions:

• Define a die with dX, where X is the maximum value of your die. For example: d6, d20, etc.
• Define a set of dice using +. For example, d12+d6 defines a d12 and a d6 that will be rolled together.
• Use NdX as a shortcut to roll the same die multiple times, where N is the number of dice. For example, 3d6+2d12 is equivalent to d6+d6+d6+d12+d12.
• Add a modifier (constant) by using +X. For example, d6+3 adds 3 to any result of the d6.

When ready: If your input is valid, just hit "roll" and you'll get a result! 😊

Advanced Usages:

• Spaces are ignored, so d6 + d12 is equivalent to d6+d12.
• An exploding die (a die that is rerolled when it reaches its maximum value) is defined by dX!E, where E is the maximum number of rolls. For example, d6!2 represents a d6 that can be rerolled once (for a maximum value of 12). If E is omitted, it defaults to 3. For instance, d12! is a d12 that can be rerolled twice when reaching its maximum value.
• To select the Q best dice rolls, use bQo(dice). For example, b2o(3d6) selects the two best rolls from 3d6. If Q is omitted, it defaults to 1. For instance, bo(2d12) selects the best roll from 2d12. Note: Q must be smaller than the total number of dice.
• You can also select the worst Q dice rolls using wQo(dice).
• Any text following a ; is ignored. This can be useful for adding notes or explanations in the roll history.
