Across
  1. 3. A piece that allows marble paths to cross without interfering.
  2. 5. A sequence of steps designed to solve a problem; Turing Tumble puzzles require building algorithms.
  3. 8. Storage of values using gear bits.
  4. 10. Steps the machine takes while solving a puzzle (like a CPU executing instructions).
  5. 13. Logic that depends on previous states; gear bits demonstrate this.
  6. 14. The stored value of a piece, such as which direction a gear bit is pointing.
  7. 17. The final configuration or result after marbles interact with the pieces.
  8. 19. The main blue grid where all parts attach and where marbles travel.
  9. 21. The part of the board that uses ramps and selectors to simulate binary logic.
  10. 22. The initial setup or the marbles released that start a computation.
  11. 23. extra formatting, no bullets — just **word → tab → definition**.
  12. 24. A piece that redirects a marble left or right as it falls.
  13. 26. A gear that flips between two positions (0 and 1), storing a binary value.
  14. 28. A number system using only 0s and 1s.
  15. 29. Recreating computing concepts using physical pieces.
  16. 30. When a marble hits a piece and causes a change of direction or state.
Down
  1. 1. A piece that catches or stops marbles from going further.
  2. 2. A piece that flips back and forth each time it's triggered.
  3. 4. Groups of bits that store multi-bit numbers.
  4. 6. A mechanism that performs a logical operation like AND, OR, or NOT. Turing Tumble puzzles demonstrate these with ramps and gear bits.
  5. 7. Directing the path of marbles to influence the computation.
  6. 9. When an output affects future behavior (like resetting a gear bit later).
  7. 11. A single action or behavior triggered by placing pieces on the board.
  8. 12. The route marbles follow downward due to gravity.
  9. 15. Logic where outputs depend only on current inputs.
  10. 16. A rotating piece used to store and change information.
  11. 18. Changing a bit or redirecting a marble based on previous interactions.
  12. 20. Finding and fixing issues when the marble paths don’t behave as expected.
  13. 25. are all your vocabulary words **combined with the provided definitions**, separated by **one tab** exactly as requested.
  14. 27. A basic unit of information (0 or 1). In Turing Tumble, some parts represent bits.
