The Automatic Dice Roller (ADR) is a handheld device that simulates dice rolls for tabletop RPGs. You can quickly calculate the total damage of a fireball (8d6) in under a second.

• Automatically add up dice rolls
• Switch between damage types
• Tactile gaming keyboard switches
• Check your average d20 roll to see how you’re rolling

The ADR can be used to roll d2, d4, d6, d8, d10, d12, d20 and d100s. The ADR can roll with advantage and disadvantage (rolling 2 dice and taking the highest or lowest result). Modifiers can also be used to add or subtract from the dice rolls.

The device can be powered over USB C using the included cable. It can be connected to various devices such as laptops, computers, USB mains adapters and power banks sold separately.
