Free 3D Online Dice Roller & Coin Flipper for Math & Classroom Games
Real dice roll off desks, get lost under bookshelves and are hard to see from the back row. These virtual 3D dice and coins never go missing, and everyone can read the result on the board. In elementary math, roll two or three dice and have students add the faces before the total appears, roll again to build multiplication facts, or flip coins and roll dice dozens of times to discover probability for themselves — the live heads-and-tails tally and the roll history make it easy to compare predictions with real results. The same tools run classroom board games, review games and partner activities: choose classic white dice or bright pastel ones, roll up to six at a time, and let the automatic sum keep score. It works in any browser on Chromebooks, iPads and interactive whiteboards, with satisfying sound effects and nothing to install.
Roll dice or flip coins in 3 steps
Pick dice or coins. Choose Dice Roller or Coin Flipper, then how many to roll at once — from 1 to 6. For dice, pick Classic D6 (white with black pips) or Pastel Colors.
Roll! Press Roll the Dice, tap the dice themselves or hit the Spacebar. The dice tumble in 3D with a clatter (coins flip with a clink) and land on the result, with the total added up for you.
Track the results. The last 5 rolls stay in the history list, and Coin Flipper keeps a running Heads vs Tails count with percentages — the same count the Coin Flipper tool shows, so flips in either one add up. Classroom Presentation Mode shows giant dice on the board with ads hidden.
Ways to use it in your classroom
Subitizing warm-ups for K–1
Choose Classic D6, set 1 to 3 dice and roll. Students call out how many dots they see without counting one by one, then check with the total shown under the dice. A quick five-roll routine builds number sense at the start of math time.
Build the biggest number
For place value in grades 2–4, pick Pastel Colors and roll three dice. Each die has its own color, so you can assign purple to hundreds, green to tens and yellow to ones, or let students arrange the digits to make the largest number possible.
Explore the sum of two dice
In upper elementary or middle school, roll two dice again and again while students tally each total on a class chart. Ask why 7 keeps showing up more often than 2 or 12. Roll history shows the last five rolls, so nobody loses track between tallies.
Roll for choice boards
Number six writing prompts, review questions or brain-break moves from 1 to 6, then roll one die to pick. Rolling in front of the class makes the choice feel fair, and when you roll two dice, doubles set off confetti that can earn a bonus round.
Frequently Asked Questions
Is this virtual dice roller truly random?
Yes. Every die and coin is decided by your browser’s cryptographically secure random number generator, so each face of a die has exactly a 1 in 6 chance and each coin a 1 in 2 chance. The spinning animation happens after the result is chosen and never changes it.
Can I roll multiple dice at once?
Yes. Roll 1 to 6 dice together — the tool adds up the total for you and cheers when they all match (Doubles!, Triples! and more). You can also flip up to 6 coins at once.
Is it free for classroom presentation?
Yes, it’s 100% free with no sign-up. Classroom Presentation Mode fills the screen with extra-large dice or coins for a projector or smartboard, hides all ads, and lets you roll with the Spacebar or a presentation clicker.
Can I roll a 10-sided or 20-sided die?
Not at the moment. The dice roller uses standard six-sided dice (D6), with opposite faces adding up to 7 like real dice. You can roll from 1 to 6 of them at a time, and the tool adds up the total for you, which covers most elementary math games and board-game style activities.
How do I see earlier rolls?
Below the dice, Roll history lists your last 5 rolls, showing each die’s number and the total (or the heads and tails count for coins). Press Clear to empty it. The history is kept only while the page is open, so copy results onto paper or a class chart if you want a longer record.
Can I turn off the sound or the spinning animation?
Yes. The speaker button mutes the dice clatter and coin clink, and that choice is saved for next time. If your device is set to reduce motion, the dice and coins skip the tumbling animation and show the result right away — the result is chosen fairly either way.
