This is an entertaining coin tossing tool. Results are generated randomly.
Online coin toss
Our coin toss simulator will help you make a decision when you can't decide between two options. Just toss a coin and let chance decide for you!
The simulator uses a cryptographically secure random number generator, ensuring an equally likely result (50% heads, 50% tails) for each throw. You can choose from three coin styles: classic, gold, or emoji. Each throw is accompanied by a realistic animation, and statistics show the total number of throws, the number of heads and tails. The history of all throws is saved in the current session, and you can copy the results for future use. The simulator is fully adapted for mobile devices and works offline after the first download.

Generator randomness check
Analysis of the distribution of results to check the quality of the random number generator
Input:
Number of throws: 100, Style: classicCalculation:
100 independent tosses, each with a 50% probability of heads and tailsResult:
Results: Heads: 52 times (52%), Tails: 48 times (48%), Total: 100 throws. The distribution is close to the theoretical 50/50, which confirms the quality of the generator.
Type: quality
Using probability theory to teach
Demonstration of a classic example of equally probable events
Input:
Experiment: 20 throws, Style: gold, Purpose: study of probabilityCalculation:
20 throws with equal probability for each outcome. Theoretical probability: P(heads) = P(tails) = 0.5Result:
Results: Heads: 11 times (55%), Tails: 9 times (45%). The practical result is close to the theoretical probability of 50/50, demonstrating the law of large numbers.

Frequently Asked Questions
Is it possible to customize the coin?
Yes, you can choose from three design styles: classic (standard coin), gold (stylized gold coin), or emoji (visual representation using emoji icons).
Are the results really random?
Yes, the simulator uses a cryptographically strong JavaScript random number generator (Math.random()), which ensures an equally likely result for each throw (50% heads, 50% tails).
Is it possible to toss several times in a row?
Yes, you can flip a coin an unlimited number of times. Each throw is independent of the previous ones and has an equal probability of landing heads or tails.
Are the statistics saved?
Statistics are saved in the current browser session and show the total number of throws, the number of heads and tails. Statistics are reset when the page is refreshed or the browser is closed.
Is it possible to copy the results?
Yes, you can copy the roll results to the clipboard using the 'Copy' button. The copied text includes the result (heads or tails), coin style, and roll statistics.
Is there animation?
Yes, there is a realistic coin toss animation of approximately 300 milliseconds for visual feedback and improved user experience.
Is it suitable for decision making?
It is an entertaining tool designed to help you make simple everyday decisions. Not recommended for important life or financial decisions.
Can it be used on mobile devices?
Yes, the simulator is fully adapted to work on smartphones and tablets. The interface is optimized for touch control and various screen sizes.
Is it free to use?
Yes, the simulator is completely free and does not require registration. Use it as many times as you need without restrictions and without the need to create an account.
How do statistics work?
Statistics automatically tracks each flip and shows: the total number of flips (flipCount), the number of heads (headsCount) and the number of tails (tailsCount). Statistics are updated after each new throw.
Is it possible to reset statistics?
Yes, use the button 'Strete' for pridi stories of rows and statistics. This is certainly meters to zero and succeeds all saved results.
Is the throw history saved?
The history of all throws is saved in the current browser session. You can view the sequence of all results, but the history is not saved between sessions or page reloads.
What is the probability of getting heads or tails?
The probability of getting heads is equal to the probability of getting tails and is 50% (0.5) for each throw. This is a classic example of equally probable events in probability theory.
Is it suitable for teaching probability theory?
Yes, the simulator is ideal for demonstrating the concepts of probability, equiprobable events and the law of large numbers. You can experiment with multiple rolls to study the statistics.
Can it be used for games?
Yes, the simulator can be used for board games where you need to randomly choose between two options, or for games with children where you need to determine who goes first.
Does it work without the Internet?
Yes, after the first download the simulator works completely offline. All calculations are performed locally in the browser and no internet connection is required to generate random results.
Can it be used to resolve disputes?
The simulator can be used to amicably resolve minor disputes or to choose between equally valid options, but is not recommended for serious conflicts or important decisions.
What algorithm is used to generate random numbers?
Uses JavaScript's built-in pseudo-random number generator (Math.random()), which provides a cryptographically strong distribution and enough randomness for entertainment purposes.
Is it possible to change the probability of getting heads or tails?
No, the simulator is specifically configured to produce equally probable outcomes (50/50) for heads and tails, which corresponds to a real physical coin toss. The probability setting is not available.
Can it be used to generate random numbers?
Yes, the simulator can be used as a binary random number generator (0 or 1, heads or tails) for various purposes: decision making, training, testing algorithms.
Is there a limit on the number of throws?
No, you can flip a coin an unlimited number of times. The only limitation is the amount of browser memory for storing the history of throws in the current session.
Can it be used for drawing lots?
Yes, the simulator is great for tossing up between two options. For example, to determine the team that starts the game, or to choose between two equivalent options.
How does the toss animation work?
The animation is a visual effect of the coin spinning, which lasts about 300 milliseconds. This creates a realistic feeling of flipping a physical coin before displaying the result.
Is it possible to export the results?
Currently, results can be copied to the clipboard, but direct export to a file is not available. You can manually save the copied text to a file for later use.
Is it suitable for studying statistics?
Yes, the simulator is ideal for learning the basics of statistics: frequency of events, probability, distribution of results, the law of large numbers. You can experiment with different numbers of throws.
Can it be used to make a decision between multiple options?
To choose between two options - yes. For three or more options, it is recommended to use a random number generator or dice calculator (D4, D6, D8, etc.) from our entertainment section.
What's the difference between coin styles?
The only difference is in the visual presentation. Classic coin - standard design, gold - stylized gold coin, Emoji - icons instead of the image of the coin. The probability of results is the same for all styles.
Can it be used for testing algorithms?
Yes, the simulator can be used to test algorithms that require binary random inputs. Each roll represents an independent random event.
Is it suitable for business decision making?
No, the simulator is intended only for entertainment and making simple everyday decisions. For business decisions, it is recommended to use professional analysis tools and specialist consultations.
Can probabilities be used to teach children?
Yes, the simulator is great for teaching children the basics of probability theory in a playful way. Kids can experiment with shots and watch the stats get closer to 50/50 with more shots.
