Sol dreamt of a strange world...

...full of rules and wonder...

They journeyed on until...

Sol awoke in an unfamiliar dark cave!

This seemed to alarm a mysterious knight
who ran off in a hurry.

Oof...I'm awake now, right?

Who was that knight?

...And where am I?

You're in Null Point — a faraway cave,
high up in the mountains.

AH! Luna, where'd you come from?!
I thought you were just part of my dream!

That's usually the case, yes. I was able
to follow you here using my powers...

...but I can't stay for long. I'll have to
leave and rest for a while after this.

Really...? But I still don't
remember anything about myself...
what will I do after you leave?

Don't worry, Sol...I think there's a
solution to your lost memories. Remember
the teddy bear you found earlier?

Oh yeah...I heard a voice when
I held that bear. It seemed familiar.

Exactly. I believe there are
other objects in this world that will help
you unlock memories of your past.

...And I'm sensing an object like that at
the exit of this cave. Sol, you must find it.

Woah! Luna, what was the crashing noise
just now?!

How can this be...?
Sol, the exit is caving in!

W-what?! What should I do??
We need to get out of here!

Hmmm...first, let's stay calm.
We still have time, just less than I thought.

You can do this, Sol — escape the cave
by using your rewriting power!

How can I do that...?

Look around you...doesn't some of this
seem familiar?

...Oh, you're right! It looks a little different, but there are objects, blocks, and rules here like the ones in my dream.

Indeed. This cave has objects
like rocks, mushrooms, and fossils.

As for object blocks — there's a block
for mushrooms, Sol, fossils, and gold.

Yeah! There's also the connector block...

And a state block. Hmm, this one says SINK.
I don't think I know that one.

Can you tell me what it means, Luna?

Hm...remember Sol, I won't always
be here to give you the answer.

Instead, I can show you how to approach
problems that are new or unfamiliar.
That should be more useful for you.

After all, the first step to solving
a problem is to understand it.

And the more you understand a
problem, the more your rewriting
power ​grows when you WIN.

Really? Okay then, I'll try...
but where do I start?

Let's try this —
Make new rules with the SINK block
by using these 3 object blocks.

...New rules? Oh! So I should try
making SOL IS SINK, FOSSIL IS SINK,
and GOLD IS SINK?

Exactly. And each time you make a new rule,
be sure to pause and notice what happens.

You may not solve the problem right away,
and that's okay. What's important is that
you try it and think for yourself first.

Right...I just need to try my best.
Let's do this!

Discuss with a partner and be ready to share out after 2 minutes.

Good work trying this problem
by yourself, Sol.

But I haven't even solved it yet...

That's fine! Remember, understanding
a problem is only the first step.

What are the other steps?

Here...I wrote them on this scroll
for you. These are the 4 steps I use
to solve problems.

For now, let's only focus on the
first step: understanding the problem.

Right. How can I understand blocks
and rules I've never seen before?

You’ve actually already started
doing it...by using a powerful strategy
called tinkering.

Tinkering? What's that?

Tinkering is like experimenting – you try something new, then pause to notice and understand what happened.

Try something new...? Is that why
​you told me to try making new rules
with the SINK block?

Yes, that's an example of tinkering.
There are many ways we can tinker
in this world.

For example, right now the
MUSHROOM IS SINK. Sol, what would you do
to learn more about how that rule works?

Hmm...my first idea is to go
touch the mushrooms and see what happens.

That’s a great idea. Touching an object
to see what happens is one way to tinker.
Why don’t you try it?

Okay...I’m kind of scared it’ll
be a mistake though.

That’s understandable, but remember
that mistakes help us learn new things.

Also, don’t forget you can undo and
start over as many times as you need.

Oh, that’s true. Alright, here I go...!

Waaaahh!!

Okay, let's undo.

Are you alright, Sol?

OMG...that was scary, but also kind
of fun? I didn’t know you could sink
in mushrooms like that...

Aha, now this is the important part of
tinkering – after you try something,
pause and think about what happened.

So let me ask you, Sol:
What did you notice after trying that?

Hmm...I noticed that walking on
the mushrooms made me disappear.
But that’s not all...

The mushroom that I walked on
also disappeared! Is that how SINK works?

Good observations!
Let's keep tinkering to learn more.

Knowing what happened in your first
experiment, what do you want to try next?

I'd rather not sink again, so...
maybe I could try pushing these fossils
into the mushrooms instead?

Pushing objects together to see what
happens is another way to tinker.
Go ahead and try it.

What did you notice that time, Sol?

When I pushed the fossil onto
the mushroom, both objects disappeared.

Very good. Let's move on to
what I had you try earlier...

You made 3 new rules with these
object blocks and the SINK block, right?

Yeah! After each rule,
I noticed something different.

Good, that's a key way to tinker –
make or break a rule, then notice
what happens to the object.

What did you notice
when you wrote SOL IS SINK?

After making SOL IS SINK,
nothing happened right away...

But when I tried walking on the water,
both the water and I disappeared!

I do need to get rid of the water
since WATER IS DEFEAT...but it won't
help if I sink too!  

So I broke the SOL IS SINK rule
and tried writing a new rule! 

Good thinking. Next you tried GOLD IS SINK,
yes? What did you notice then?

When I wrote GOLD IS SINK, I noticed
something right away – the 3 golds and the
water they were on all disappeared!
