Watch, listen, learn

Play the animated tutorial or have each step read aloud until the rule actually clicks.

Animated tutorials

Watch every step play out.

Terms highlight, move, and transform on screen so you can see exactly what happens between one step and the next, not just read about it. It's like having a tutor draw it out for you.
