Roll 1d9 online – a 9-sided die










MODIFIERS
Add bonuses, penalties or multipliers. They apply from top to bottom.




1d9 · one choice from 9 outcomes

A little world in a 3 × 3 grid 🧩

Nine outcomes make a D9 a useful address picker for a small board. It can also choose one of nine names, prompts, or activities. Number the entries clearly and the unusual die size becomes an ordinary practical tool.

🐈 D9 Roller - Nine Outcomes and One Completely Unlicensed Cat Auditor

Nine is uncommon enough to feel odd, but still small enough that every result fits in one digit. This pleases both humans and cats, for unrelated reasons.

🔎 Audit finding

Use D9 for nine-entry tables, character quirks, classroom picks, scene prompts or any list that stubbornly refused to stop at eight.

🐾 About the nine lives thing

The cat declined to confirm the exact number of lives. It did confirm that a 9 on the die does not grant an extra one.

1/9 each

Each face is about 11.11%. Repeated 9s are coincidence, not feline intervention.

🍜 Kitchen rule

The cat has nine lives and still refuses responsibility for the broth.

Nine entries with a little room for quirks

  • Nine-entry random tables without rerolling a D10.
  • Picking one of nine rooms, NPCs or objectives.
  • Random digits from 1 to 9.
  • Homebrew systems that deliberately avoid standard polyhedral sizes.

If your table really has nine entries, a D9 is cleaner than rolling a D10 and rerolling 10.

The center square is number five

Number a 3 × 3 grid from left to right, top to bottom: 1–3 in the first row, 4–6 in the second, and 7–9 in the third. A 5 selects the center. Each square has a one-in-nine chance, approximately 11.11%.

Numbered squares and coordinates are two useful choices

Use one D9 for a numbered grid square. If you prefer coordinates, read two D3s separately as row and column. The individual pair matters; its sum loses the coordinate information.

Give the grid a shared reading order

Number nine positions, nine character traits, or nine available activities. Agree on the numbering before the roll so the result is easy for everyone to interpret.

Nine squares share the board evenly

11.11%per named result in the uniform-die model

The average face is 5, which is also the center square in the illustrated numbering. The center is still no more likely than any corner: each square has one of nine outcomes.

Two coordinates need two separate D3s

Adding two D3s does not choose nine positions uniformly. The sum ranges only from 2 to 6. Two separately labeled D3 rolls can instead select a row and a column, giving nine equally likely pairs.
