Virtual eight-sided die (D8)

The D8 is a standard die in tabletop RPGs like Dungeons & Dragons, used for damage rolls (longsword, greataxe hit dice), random table lookups, and movement distances. This tool replicates it digitally: each value from 1 to 8 has a 12.5% chance on every roll. For animated dice faces across multiple die types, see the dice roller.

Pool mode: eight-value cycle

Pool mode cycles through all eight values in shuffled order before repeating. This is useful for game scenarios requiring each die face to appear once per round, or for assigning turns fairly among eight players with guaranteed no repeats in a single cycle.

Distribution: individual face tracking

After 10 rolls, the distribution chart shows a bar for each value (1 through 8). Over many rolls, all eight bars should approach equal height — confirming the 1-in-8 probability per face. This mirrors the uniform distribution of a fair physical D8.

Frequently asked questions

Is this the same as rolling a D8?
Yes. Each value from 1 to 8 has a 12.5% chance per roll — the same probability as a fair eight-sided die. The generator uses Math.random() seeded from hardware entropy.
Can I use this for tabletop RPGs?
Yes — it is a direct digital equivalent of a D8. For animated dice faces or rolling multiple dice at once, try the dice roller. For a D6, see the 1–6 generator.
What is pool mode for 1–8?
Pool mode cycles all eight values in shuffled order. Each appears exactly once per cycle before any repeat — useful for fair eight-player turn assignment or controlled RPG table generation.
