Dice Drop

Dice Drop is a 3D physics dice roller for the browser, iPhone and Android. The dice tumble, collide and settle in a virtual tray, and the result is read from the face that lands up, with randomness seeded from a cryptographically secure source. It needs no account and works offline.

It covers every common die from D1 to D120, including percentile dice, with built-in advantage, disadvantage and modifiers, a running total, roll history and lifetime statistics kept on the device. You can also set up custom two-sided dice for quick calls such as heads or tails, hit or miss, or yes or no.

The app includes offline guides for tabletop games such as D&D, Pathfinder, Call of Cthulhu and Yahtzee, explaining how each game uses its dice and the odds involved. For group play, players can share a four-letter room code to see each other's rolls live or pass one device around the table, and rolls can be sent to Discord.

Dice Drop is free for up to four dice per roll and shows a single banner ad. An optional one-time Premium purchase adds mixed pools of up to 20 dice, saved macros, extra finishes and tray surfaces, physics tuning and multiplayer features. There is a 7-day free trial and no subscription.
