Pick your dice count and sides, then roll — individual results, total, highest and lowest shown instantly.
The standard notation is XdY: X dice with Y sides each. 2d6 means two six-sided dice — the classic Monopoly-style roll; 1d20 is the heart of Dungeons & Dragons. This roller supports 1–10 dice of d4 through d20.
Fun fact: two six-sided dice are far more likely to total 7 (6 ways out of 36) than 2 or 12 (1 way each) — that asymmetry powers games from Ludo to backgammon.
Board games on the go: dice get lost under sofas — your phone doesn't.
Dungeons & Dragons and tabletop RPGs: quick d20 rolls without hauling a dice bag.
Classrooms and decisions: fair, transparent random picks everyone can see on one screen.
Board gamers and role-players write dice as dN: d6 is a standard die, 2d6 means roll two six-sided dice and add, and 2d6+3 adds a modifier. The notation scales to any shape — d4, d8, d10, d12, d20 — and a d100 (two ten-sided dice read as tens and units) is the engine of percentile systems. This page simulates the classic d6.
Dice predate almost every game you own. Dice over 4,000 years old were excavated at Shahr-e Sukhteh in Iran, paired with a backgammon-style board, and knucklebone dice are older still. Six-sided cubes became the standard because they roll fairly and are easy to carve — geometry doing the work of fairness.
With one die, every face 1 to 6 has an equal 1/6 chance. With two dice, outcomes combine: there are 36 equally likely pairs, and seven is the most likely total with 6 of those 36 combinations (about 16.7%), while 2 and 12 each have just 1 in 36 (2.8%). The distribution is a symmetric hill around seven.
That single fact powers casino games like craps and dozens of board-game strategies — Monopoly's orange properties pay because they sit 6, 8 and 9 from jail, the most likely rolls. When a game feels tuned, it is usually tuned to this hill. Our roller reproduces these exact probabilities with fair, uniform randomness.
