Percentages Game

<p>A game for two or more players. A 4 by 4 grid contains different percentages of the number 630. (Why 630? Not too easy; not too hard - I hope. Replace with your own number if you prefer.) A list of the percentages used is given. Players take it in turns to pick a percentage and the number in the grid which they think matches it. If they are right; they can put a counter on that grid square. The first to get four in a row wins. Answers provided.</p>
