Random Number Between 1 and 2
A clean binary pick — the number-form coin flip
A random number between 1 and 2 is the simplest fair chance you can run — a 50/50 split in number form. It's a coin flip without the coin, which makes it handy when you want a binary decision written down as a clean digit instead of "heads" or "tails".
When a 1-or-2 pick fits
- Deciding between two options when you genuinely don't mind
- Randomly assigning one of two groups, teams or test conditions
- A/B test sampling in classroom or research exercises
- Choosing who goes first in a two-player game
- Simulating coin flips in scripts and spreadsheets
Prefer heads or tails?
If you'd rather see the result as a coin, use the Coin Flip tool — same fairness, friendlier visuals. For yes/no style questions, the Yes / No Wheel is made for it.

Frequently Asked Questions
Is this really 50/50?
Yes. Each generation has exactly a 50% chance of 1 and a 50% chance of 2.
Why would I pick 1 or 2 instead of heads or tails?
Numbers are easier to paste into spreadsheets, log in research notes, or map to any two-option list you already have written down.
Can streaks of the same number happen?
Yes, and they're completely normal. Over 10 flips, a run of four or five of the same is not unusual. Fairness is about long-run averages, not short streaks.
