Home/Even or Odd Number
The same draw as a plain random number, with everything of the wrong parity taken out of the hat first — so asking for an even number between 1 and 9 draws from four possibilities, not nine.
Press Draw
The range is narrowed to the numbers of the kind you asked for and then one is drawn evenly from those. It is not a number drawn and then checked, which would have to try again and would take longer on a narrow range.
If the range holds no number of that kind — an even number strictly between 3 and 4 — it says so rather than spinning.
Set it to either and it draws from the whole range, which is worth having when what you actually want is a number and the parity is somebody else’s guess.
Everything happens on your device; nothing is sent anywhere.
