D-ROLLER
D-Roller is a free online dice roller built around a real rigid-body physics engine rather than a random number generator. Every throw is simulated — sequential impulses at a fixed 360Hz, full collision between dice, friction and restitution — and the result is read off the geometry of whichever face ends up pointing at the ceiling. Nothing is drawn in advance and nothing can produce a number without the dice actually being thrown.
It carries the full polyhedral set — D4, D6, D8, D10, D12 and D20 — and up to twenty dice on the table at once in any mix, so an attack and its damage are one throw rather than two.
It also reads a roll the way a table does. Two D20 are shown side by side and never added, because two twenties are advantage or disadvantage and no such total exists; a D20 thrown beside damage dice keeps the attack as the headline and the damage underneath; and a D10 that lands on 0 counts as ten, the way the printing on a real one means. Five die finishes, seven table surfaces, impact sound, and a stage the player can relight.
No account, no download, no advertising in the roller. It runs in the browser, on a phone as well as a desktop.
