How the Coin Flip & Dice Roller Works

Click to flip the coin or roll up to 6 dice. Results use crypto.getRandomValues() — the same cryptographic RNG browsers use for HTTPS — so outcomes are statistically indistinguishable from true randomness.

The coin section logs your last 10 flips with a running heads/tails count. The dice section shows the last 5 rolls with individual die faces and totals.

Tips for Fair Decision Making

  • Assign outcomes before flipping. Decide which side means which outcome before you flip, not after — post-hoc assignment defeats the purpose.
  • Notice your reaction. The moment the result appears, pay attention to how you feel. Disappointment reveals your true preference more honestly than extended deliberation.
  • Two dice = 7 is most likely. With two d6, 7 can be made 6 ways out of 36 combinations. 2 and 12 each have only one way — six times rarer. Useful to know for board games.

Frequently Asked Questions

Is the coin flip truly random?
Yes. Results use crypto.getRandomValues() — the same cryptographic RNG browsers use for HTTPS. It is statistically indistinguishable from true randomness and cannot be predicted.
Does a past result affect future flips?
No. Each flip is completely independent. Believing otherwise is the gambler's fallacy — after 10 heads in a row, the next flip is still exactly 50/50.
Can I flip multiple coins at once?
The coin section flips one at a time. For multiple simultaneous results, use the dice roller — roll one die per "coin" and treat odd as Heads, even as Tails.
