About this tool
Coin Flip is a free online game. Flip a coin online, heads or tails randomly. Play instantly — no install, no waiting. It runs entirely in your browser — no download or sign-up needed.
Click the toss button, and the coin will flip a few times on the screen and then fall, randomly showing the head or tail. The result is a 50/50 probability, each throw is independent. You can throw it multiple times in a row, and the tool will count the number and proportion of positive and negative occurrences.
The flip animation is implemented using CSS 3D rotateY, and the front and back are two sides. Math.random() determines which side is ultimately displayed, and the animation is just a visual effect.
Suitable for when you need to make an alternative decision-do A on the front and B on the back. It is also suitable for probability teaching demonstrations. After throwing it enough times, the ratio of positive and negative will approach 50%. It is more convenient than physical coins, so you don't have to worry about not being able to find it when you drop it.
Online coin toss tool, simulating real coin toss, displaying positive or negative results, with animation effects, suitable for making random decisions.
