It looks like you kept the "messageSelectorAndArgumentNames" part of the
template.  So what you have now is:
* a method called messageSelectorAndArgumentNames
* which uses a temporary variable "initialize" (when you wrote "initialize"
on a line by itself, Squeak thought it was an undeclared temporary variable
(which is why it added the declaration | initialize |)

You should have:
     "create quinto game"
     super initialize.
     self label:''.

i.e. "messageSelectorAndArgumentNames" and the rest of the template gets
replaced with your code
n.b. "self turnOf" should be "self turnOff"

A few things:
1. As someone pointed out before, methods are case-sensitive i.e.
initialize, not Initialize
2. The more detailed and precise the better - when you say inspect "it,"
what is the it?  So that people can support you, clearly state the steps to
reproduce what you're talking about.  The community is friendly and
supportive, and if you put in the effort to ask a good question, this will
be multiplied.
For example:
1. inspect from workspace: "SBECell new"
2. in inspector, doit: "self openInWorld"
3. error: "SBECell does not understand..."
