When discussing coin flips and probability, it’s important to distinguish between theoretical ideals and real-world results.
Ideally, with a perfectly balanced coin and a perfectly random flip, the probability of landing on heads or tails is indeed 50/50.
However, in reality, various factors can subtly influence the outcome of a coin flip, leading to a slight bias that deviates from the perfect 50/50 split:
- Starting Position: Studies have shown that a coin lands on its starting face more often than not, potentially due to the way people flip coins, introducing a slight wobble that favors the initial side.
- Engravings and Weight Distribution: Slight variations in a coin’s engravings or weight distribution can subtly affect its balance and favor one side over the other.
- Flipping Technique: The way a person holds and flips a coin can introduce a bias, making one side more likely to appear.
These real-world factors can lead to a slight bias, making the coin flip closer to a 51/49 probability rather than a perfect 50/50.
Google’s coin flip, like most online coin toss simulators, uses a pseudo-random number generator (PRNG) to produce the results. While these generators aim to create results that are statistically random and closely approximate a 50/50 outcome over a large number of flips, they are still based on algorithms and are not truly random.
For most practical purposes, the difference between a truly random coin flip and a pseudo-random online simulation is negligible. While the possibility of a slight bias in real-world coin flips exists, the Google coin flip is designed to produce results that are as close to a 50/50 probability as possible using algorithms.

The Role of Randomness in Google Coin Flip
Flip appears random, it is important to note that it relies on pseudo-randomness. This means that the results are not truly random, but rather deterministic and reproducible based on the inputs.
Is a coin flip really 50/59?
From my experience, The findings backed up the original research: coins are likely to land on the same side they started on 50.8 per cent of the time. Crucially, though, the team found large variations in flippers.
