Practice Guide

Version 1.0 - Covers challenges 1 to 30

Let’s practice!

Welcome to the Turing Tumble Practice Guide! This is a free companion to Turing Tumble. This version of the guide covers the first 30 challenges in the book. If it’s useful, we’ll do the same for the rest of the challenges.

The purposes of this guide are:

1. To cement important concepts. Practice challenges give another opportunity to apply what you learned. 2. To offer hints when you’re stuck. Solve a practice challenge or read the explanation of the solution. This guide lowers the learning curve. 3. To learn how puzzle solutions work. Each solution has an explanation that describes how it works. 4. To offer the puzzles in an easily printable black and white format. Make as many copies as you like.

What is the best way to use this practice guide? The practice guide is meant to be used alongside the Turing Tumble puzzle book, but it’s not meant to replace it. Unlike the Turing Tumble puzzle book, it doesn’t contain instructions for how to assemble the computer, how to play, how the parts work, and other bits of useful information.

Starting setup Available parts

Objective: Make all of the blue balls (and only the blue balls) reach the end.

Required output:

x 8 x 8 x 4

PRESSSTARTTO

Challenge 1: Gravity

Starting setup Available parts

Objective: Make all of the blue balls (and only the blue balls) reach the end.

Required output:

x 8 x 8 x 3

PRESSSTARTTO

Practice Puzzle A for Challenge 2

Explanation: The ramps fill the gaps in the path from the top of the board to the bottom of the board.

x 8 x 8

PRESSSTARTTO

Practice Challenge 2-A Solution

Explanation: The starting setup leads the balls over onto the right side. That’s a problem! If the balls hit the right lever, they’d release red balls, but you’re only supposed to let the blue balls get to the bottom.

To solve this puzzle, you have to use the 5 ramps to lead balls back over to the left lever.

x 8 x 8

PRESSSTARTTO

Challenge 2 Solution

Starting setup Available parts

Objective: Start the machine by releasing the blue ball. The blue ball should then release the red ball.

Required output:

x 1 x 1 x 8

PRESSSTARTTO

Practice Puzzle A for Challenge 3

Starting setup Available parts

Objective: Release one blue ball and then all of the red balls.

Required output:

x 8 x 8 x 6

PRESSSTARTTO

Challenge 3: Ignition

Explanation: Like the last puzzle, the ramps bring the paths of the red and blue balls into one path that leads to the right lever. After the first blue ball, all the rest are red.

x 8 x 8

PRESSSTARTTO

Challenge 3 Solution

Explanation: The paths of the blue and red balls come together near the bottom of the board and then lead to the red side. Since all paths lead to the red side, only red balls are released after the first blue ball.

x 8 x 8

PRESSSTARTTO

Practice Challenge 4-A Solution

Starting setup Available parts

Objective: Release one red ball and then all of the blue balls.

Required output:

x 8 x 8 x 6

PRESSSTARTTO

Practice Puzzle B for Challenge 4

Starting setup Available parts

Objective: Release one red ball and then all of the blue balls.

Required output:

x 8 x 8 x 13

PRESSSTARTTO

Challenge 4: Fusion

Explanation: The paths need to come together, but they start far apart! Use the ramps to bring the paths together and lead all of the balls to the left side.
