Frequently Asked Questions

How random are the dice results?

The dice results use JavaScript's Math.random() function, which is a pseudo-random number generator. For most tabletop gaming and casual use this is perfectly sufficient. For truly unpredictable randomness (e.g. cryptographic use), a hardware-based random source would be required.

What types of dice can I roll?

You can roll standard polyhedral dice used in tabletop RPGs: D4, D6, D8, D10, D12, D20, and D100 (percentile). There is also a custom option where you can enter any number of sides — for example a D3, D7, or even a D30.

What does 'Drop Lowest Die' mean?

Dropping the lowest die means the single lowest result in a given roll is removed before the total is calculated. This is commonly used in Dungeons & Dragons when rolling 4d6 to generate character ability scores — you roll 4 dice and discard the lowest to improve your average outcome.

Can I roll multiple dice at once?

Yes — set the 'Number of Dice' field to any value between 1 and 20. All dice will be rolled simultaneously and their results summed together. You can also roll the entire set multiple times using the 'Number of Rolls' field.

What is a modifier in dice rolling?

A modifier is a fixed number added to (or subtracted from) the total after rolling. In games like DnD, modifiers come from ability scores, proficiency bonuses, or spell effects. For example, rolling 1d20 with a +5 modifier means adding 5 to whatever you roll.

How do I simulate a standard board game roll (like Monopoly)?

Set 'Number of Dice' to 2 and 'Sides Per Die' to D6. This replicates the standard two six-sided dice roll used in Monopoly, Backgammon, and many other board games.

What is a D20 and why is it important in DnD?

A D20 is a 20-sided die and is the most iconic die in Dungeons & Dragons. Nearly every important action — attacking, skill checks, saving throws — is resolved by rolling a D20 and adding relevant modifiers. Rolling a 20 is called a 'natural 20' or critical hit, while rolling a 1 is a critical failure.

Can I use this dice roller for Yahtzee or other dice games?

Yes. For Yahtzee, set 'Number of Dice' to 5 and 'Sides Per Die' to D6. The roller will show all five individual results along with the total. While the tool does not track Yahtzee scoring categories, it fully handles the dice-rolling portion of the game.
