A way to roll d20 in prison, on train or during meetings https://constantchaos.itch.io/dicefoldAnother way is rolling d20 mentally.
Without any tool or external source of randomness.
Think of two words. Count the letters in both.
If second count is even, add the count of 1st to the 10.
Otherwise subtract it.
Additional rules,
If second has 5 letters - result is 10.
If second word has less than 5 letters, then the result is 1
Ensure words don't repeat during a session.
Obviously it is not very failproof if you are smart.
Systems like ChatGPT easily roll 20ies most of the time,
making error just once per 20 rolls.
