Factorial Calculator

Difficulty: Expert

Game Overview

Design a physical track where a marble rolls and executes programming instructions. The marble carries a value and performs calculations as it hits different track pieces.

Puzzle

Calculate the factorial of 4 (4! = 4 × 3 × 2 × 1) and output the result 24.

Starting Conditions:

• Marble begins carrying the value: 4
• Expected output: 24

Available Track Pieces (Use Each Once):

• 2× CURVE - Changes marble direction 90°
• 1× STRAIGHT - Continues marble in same direction
• 1× LOOP-TRACK - Connects track to form a physical loop
• 1× BRANCH-ZERO - Marble goes LEFT if carrying 0, RIGHT otherwise
• 1× SUBTRACT-1 - Subtracts 1 from marble's value
• 1× MULTIPLY - Multiplies marble's value by memory slot A
• 1× STORE-A - Saves marble's current value to memory slot A
• 1× LOAD-A - Loads value from memory slot A into marble
• 1× OUTPUT - Displays marble's current value
• 1× HALT - Stops the marble

Rules:

• Arrange all track pieces to create a complete path
• Marble executes instructions when rolling over pieces
• Design must calculate factorial using the loop mechanism
• Marble must output 24 and then halt

Goal

The marble completes its journey, outputs 24, and stops.

Wonder Forge is a brand of the Ravensburger group, but quality is not as good, maybe closer to Master Pieces or Buffalo. Pretty good, especially at a reduced price.

This is a neat puzzle by Karen Puzzles. The big puzzle pieces are all separate puzzles making it fun and a little trickier than i would have thought.

This was a small one, so it wasn't too hard, but I can imagine the larger versions become a lot harder. Maybe I'll try the 200 piece version next.

Picked this one up from the local second hand store. It was easier than i thought it would be with all the browns and yellows.
