Pick a random person when having stick notes per participant. Or select the following topic from your board randomly.

Gamers of Board-, Card- or Roleplaying Games

Build a deck of cards and let the Randomizer shuffle it for you. You can define a card as cover card, so the next card is not visible while shuffling.
Let Randomizer pick a card from your deck or your card hand.

Roll different sized dice (D4, D6, D8, D10 or D20) by dragging them to the board. Different colors and dimensions of dice can be configured.


Load the App from the Miro Marketplace.
Open any Miro board and use the "More Apps" icon on the left side.
Search for "Randomizer" in the following dialog.


When open in Miro, start dragging dice to your board (or click dice to add in the center of the screen).
Choose your favorite color and the amount of dice you want to roll.

To handle cards, select elements on the board and pick a random card or use the shuffle functions.
To simulate a card deck, group all card graphics and add a cover card on top. Move this cover card a bit, so the edge of the playing cards is visible.
Now you can shuffle add draw from your card deck: select all elements (cards and cover card) and press "shuffle cards", draw a playing card which is partly visible below your cover card. Pro-tip: lock the cover card to avoid revealing your playing cards unintentionally. Be aware of the cogwheel icon, which opens the configuration panel and allows you to change the amount of dice and the size of the dice when dragged.
