Step-by-step instructions
Set the number of flips
Use one for a single toss or choose a batch for several independent flips. The maximum is 100.
Assign meanings before flipping
If heads and tails represent different options, agree on those meanings before seeing the result.
Flip and record the outcome
Select Flip coin. Use the order shown when interpreting a sequence and save the batch if you need it later.
Worked example
A guessing game asks a participant to predict a side before each single flip. Predictions are recorded separately from the generated values.
One valid result is shown below. Your generated outcome will vary.
Example settings
Number of flips: 1
Example result
1. Heads
The result is an outcome, not a confirmation that the participant’s prediction was reasonable or informed.
Distinguish prediction from the generated result
Keep the prediction fixed before flipping and record whether it matched afterward. A past run of heads does not make tails certain or more likely on the next independent toss. For a complete game, agree on how many rounds count and avoid changing that stopping point merely because someone is ahead or behind.
Settings and limits to check
Every flip independently selects Heads or Tails with equal probability. A batch is not forced to contain an equal number of each, and earlier outcomes do not make the opposite outcome due. Batch sizes range from 1 to 100. New generations replace the current display and do not keep cumulative counts.
Settings used in this example
Number of flips: 1
Keep a usable copy of the result
Use Copy to place the current result in your own notes, or Download to keep a text file. Keep the range, count, or other settings with the result when they are needed to interpret it. A new generation replaces the displayed result rather than adding to a saved history.
The tool runs in your browser and does not upload your input. Save the result before refreshing or leaving the page. If other people need to use the same outcome, share your saved copy rather than asking them to generate another independent result.
Frequently asked questions
Does the previous flip affect the next one?
No. Each Heads-or-Tails selection is independent of the displayed history.
Will ten flips always contain five heads?
No. Five heads is one possible count, but independent flips can produce more or fewer.
Can several heads occur in a row?
Yes. Runs are possible in independent flips and do not force the next result to be tails.
What should I check in the worked example?
The result is an outcome, not a confirmation that the participant’s prediction was reasonable or informed.
