Matchsticks Problems

Matchstick problems are among the most exciting topics for developing spatial reasoning.

Usually, there are two types of actions you can perform on problems with matchsticks:

1. Remove the matchstick.
2. Move the matchstick.

In the first case, your goal is to achieve a target structure by completely removing a certain number of matchsticks.

In the second case, your goal is to move a specific number of matchsticks to achieve the correct structure.

A key rule in this topic is:

• after you move or remove matchsticks, there should be no dangling matchsticks.
