Lunch bet: which picker do you reach for?
Someone says "I'll just pick one at random" and someone else objects immediately. If you pick it, that's not a draw.
Fair point. Ask people to name any number from 1 to 10 and the answers pile up on a few favorites. Ask them to pick from a list and they avoid the first and last rows. Human hands have habits. That's what picker tools are for.
Which tool depends on what you're picking.
| Picking | Tool |
|---|---|
| Who buys the coffee | Wheel |
| One result for each person | Ladder draw |
| Presentation or chore order | Shuffle |
| One of two | Coin |
| A number | Dice |
A ladder draw (a Japanese-style lottery grid, Amidakuji) pairs names on top with results on the bottom. It's for when the number of people matches the number of results. If you only need one winner, a ladder makes you invent filler results for the other rungs. Use the wheel instead.
Landing back where you started is normal
You can ride a ladder through a dozen crossbars and still land on your own column. Someone will call it rigged. It happens on paper ladders too, and not rarely. That's a result. Redrawing because you didn't like it is the one move that actually is unfair.
Three heads in a row doesn't mean tails is due
A coin doesn't remember. Three heads in a row, and the fourth flip is still fifty-fifty. "It's due" is the most common myth at any draw. When someone wants to reshuffle the whole game because of it, side with the coin.
Pickers that smooth the results are no fun
Some picker tools quietly keep the same person from losing twice in a row. It looks considerate. But the moment everyone knows the tool touches the results, the loser stops accepting them. The fun of a draw is that nobody can reach into it.
There's a ladder, a wheel, a shuffle, dice and a coin in one box. Nothing is smoothed, and every run is fresh. The ladder animates its path and the wheel spins down in front of everyone. The loser watched the same screen, so the coffee run is theirs.
