How do I control the vertical extent of a Wrapfig environment?

Question

The Wrapfigure environment should only affect the top of the document. But it is still influencing the text after the first set of tables. I've played around with the \height, the negative \vspace and the \linewidth variables. Unfortunately, the "Hint" text is still only 0.7\linewidth. How do I make it the full 100%? I'm still new at Latex, and trying to convert my InDesign classroom materials into the new format.

\documentclass[12pt,b5paper]{article}
\usepackage[top=1cm,bottom=1cm,left=2cm,right=2cm]{geometry}
\setlength{\parindent}{0em}
\usepackage{wrapfig}
\usepackage{graphicx}
\usepackage[thinlines]{easytable}
\usepackage[default]{cantarell} 
\usepackage[T1]{fontenc}
\begin{document}
\pagestyle{empty}
\begin{wrapfigure}{r}{0.3\linewidth}\vspace{-80pt}
    \centering
    \includegraphics[height=150pt]{ladder}
\end{wrapfigure}
\begin{center}
    \Huge{\textbf{Word Ladders}}\
    \vspace{8mm}
    \normalsize
\begin{minipage}{0.8\textwidth}
Change one letter from each word to go from the top word to the bottom word.
\vspace{3mm}
\end{minipage}
\end{center}
Here is an example. Go from \textbf{poor} to \textbf{rich} in six steps. The changed letter is \underline{underlined}.
