Everything you need to know about using Call to Roll

Getting Started

Creating a Room

  1. Enter your name in the text field
  2. Click "Create Room"
  3. Configure your dice sets:
    • Choose the number of dice (1-10 per set)
    • Select colors for each set
    • Add up to 4 different sets
  4. Click "Start Room"

  3. Click each die to set the value (cycles 1-6) and click the colored dot below to set the color
  4. Click "Enter Room" when the code matches

Rolling Dice

Once in a room, you'll see the dice sets configured by the room creator. To roll:

  1. Click on a dice set to "grab" it (your name appears above)
  2. Click the dice set again to roll
  3. Everyone in the room sees your roll in real-time
  4. Click another set or area to "drop" the dice

Only one player can hold a dice set at a time. If someone else has grabbed the dice, wait for them to roll or drop them.

Room Codes

Room codes are made up of 4 colored dice, each with a value (1-6) and a color (white, red, blue, green, purple, or yellow). This gives over 1.6 million possible combinations. Room codes are displayed as interactive colored dice — tap a die to change its color and swipe up/down to change its value.

Frequently Asked Questions

Call to Roll uses peer-to-peer connections, so the practical limit depends on your network. Typically, 6-10 players work well. For larger groups, some players may experience connection issues.

Connection issues are usually caused by:
- Firewall or network restrictions blocking WebRTC
- VPN software interfering with connections
- The room code being incorrect
Try disabling VPN, checking your firewall settings, or verifying the room code.
