  Roll 1 to 100 dice with 2 to 1000 sides each (default one six-sided die).

  • count — integer
  • sides — integer

  Hints: read-only yes · destructive no · idempotent no · open-world no

• flip_coin read-only

  Flip a fair coin 1 to 100 times.

  Parameters:

  • seed — string — Optional. 64 hex characters. Give the seed of an earlier answer to get the same result again (that is how a draw is checked). Leave it out for a fresh draw.
  • count — integer

  Hints: read-only yes · destructive no · idempotent no · open-world no

• random_integer read-only

  Integers from min to max inclusive, 1 to 1000 of them, with or without repeats. The range may hold at most 2^32 values.

  Parameters:

  • min (required) — integer
  • max (required) — integer
  • seed — string — Optional. 64 hex characters. Give the seed of an earlier answer to get the same result again (that is how a draw is checked). Leave it out for a fresh draw.
  • count — integer
  • unique — boolean

  Hints: read-only yes · destructive no · idempotent no · open-world no

• pick_from_list read-only

  Pick 1 or more items from a list of up to 1000, each equally likely. Without repeats by default.

  Parameters:

  • items (required) — array
  • seed — string — Optional. 64 hex characters. Give the seed of an earlier answer to get the same result again (that is how a draw is checked). Leave it out for a fresh draw.
  • count — integer
  • unique — boolean

  Hints: read-only yes · destructive no · idempotent no · open-world no

• shuffle_list read-only

  Put up to 1000 items in a random order; every order is equally likely.

  Parameters:

  • items (required) — array
  • seed — string — Optional. 64 hex characters. Give the seed of an earlier answer to get the same result again (that is how a draw is checked). Leave it out for a fresh draw.

  Hints: read-only yes · destructive no · idempotent no · open-world no

• prismtect_number read-only

  A personal two-digit number from the Prismtect glass prism, for a user who asks for a lucky number, a number of their own or a number for today. Only a human touch can draw it, so this tool gives no number: it gives the link your user taps themselves. Pass the link on.
