Speuravontuur: Operatie Pakjesavond

A Sinterklaas game for the whole family: eight puzzles, rhymes and a hunt for hidden presents through your own home.

  1. Level 1 of the game on a phone: the Hoofdpiet asks you to tap the right word in the letter from Sinterklaas.

    The puzzle

  2. The Great Book of Sinterklaas on a phone: a rhyme that reveals where the present is hidden.

    The rhyme

  3. The code screen on a phone: the player enters the four digits from the note they found.

    The code

  1. Level 1, the secret letter: a letter from Sinterklaas with a stain on one word and cards with words.
  2. Level 2, the Piet lock: sums with pepernoten, carrots and presents above a combination lock.
  3. Level 3, the maze: the Hoofdpiet stands at the entrance of a golden maze.
  4. Level 4, the rebus: pictures with letters and a row of empty boxes for the word.
  5. Level 5, the safe: clues above a safe with four digits and an Open button.
  6. Level 6, find the traces: two nearly identical rooms with a fireplace.
  7. Level 7, the sliding puzzle: shuffled pieces of a picture with the steamboat.
  8. Level 8, the finale: golden letters and a quiz question about the secret letter.

Speuravontuur is a game that turns Sinterklaas gift evening (pakjesavond) into a treasure hunt through the whole house. A letter from Sinterklaas with a QR code starts the game; then the young detectives play eight levels. In each level they solve a puzzle, read a rhyme and search the house for a hidden present.
