Learn how to play the Underground Brain Train game: set up the tiles, solve number puzzles, and get your wind-up train moving. Includes step-by-step rules and tips.

Quick Answer

To play Underground Brain Train, choose a puzzle, use the clues to select numbered track tiles that add or subtract to the target number, connect the tracks, and watch your wind-up train run along them.

Why the Number Clues Matter

Each puzzle gives you a target number and a set of clues. The clues tell you which tiles to pick based on addition or subtraction. This is the core challenge of the game – it’s not just about building a track, but about using math to figure out which tiles fit.

The game is designed for ages 4 to adult, so the difficulty can be adjusted. Younger players can start with the easier levels, while older kids and adults can tackle the harder puzzles. This makes it a great family puzzle game that grows with your child.

Choosing the Right Difficulty Level

With 40 puzzles and four levels of difficulty, you can start with the simplest challenges and work your way up. If you’re playing with a younger child, begin with the first level to build confidence. For older kids or adults, jump to a higher level for a more demanding brain workout.

Remember, the goal is to have fun while learning. Don’t be afraid to skip a puzzle if it feels too hard – you can always come back to it later.

How to Play Underground Brain Train – Step-by-Step

Set Up the Tiles: Place all twelve numbered track tiles face up on a flat surface. Make sure you have enough room to connect them into a track later. Check that all tiles are visible so you can see every number.
Choose a Puzzle: Pick one of the 40 puzzles from the booklet. Each puzzle shows a target number and a set of clues. Start with level 1 if you’re new, and increase difficulty as you get comfortable. If a puzzle feels too hard, skip it and try a lower level – don’t get stuck.
Solve the Clues: Read the clues carefully. They will tell you which tiles to select based on addition or subtraction. For example, if the target is 10 and you have tiles 5, 3, and 2, you might choose 5+3+2=10. Select the tiles that match the clues. Double-check your math – a wrong tile will break the track.
Connect the Tracks: Arrange the selected tiles in a line, making sure the track ends align so the train can run smoothly. The tiles should connect without gaps. Ensure the track is straight and even – any misalignment will stop the train.
Run the Train: Wind up your train and place it on the track. Watch it run along the tiles you’ve connected. If it stops, check the track for any loose connections or incorrect tiles. If the train doesn’t run, re-check your tile selection and alignment.
