🎲 Fun & Random calculators
The two that settle arguments. A wheel that picks a person for the job, and a coin that picks a side — once, or a hundred times with the runs counted.
Spin the Wheel
Who buys the pizza, who gets the beers in, who drives? Put the names in, spin, and let the wheel settle it.
Open the wheel →Coin Flip
Heads or tails, settled in one toss — or a hundred of them, with a count that follows the runs.

What are the odds of the same name twice?
With four names on the wheel, each one is 25%. The same person twice in a row is 1 in 4; three times running is 1 in 64. The wheel has no memory, which is the part that feels wrong.

Is 50 heads in 100 flips likely?
It is the single most likely result and still only happens 7.96% of the time — less than one run in twelve.

How odd is 60 heads in 100 flips?
Less odd than it looks. Forty-five to fifty-five heads covers 72.9% of runs, and 60 heads still turns up 1.08% of the time — about one run in ninety-two.
