This is probably a better solution than my first, but you can be the  
judge  
of that.

class Wordsearch  
DIRECTIONS = [[1,0],[-1,0],[0,1],[0,-1],[1,1],[1,-1],[-1,-1],[-1,1]]  
def initialize(wordsearch,words)  
@words = words  
@rows = wordsearch.split(/\s+/).delete\_if { |row| row == “” }  
@points = {}  
@letterPositions = []  
@rows.each\_with\_index do |row,y|  
row.split(//).each\_with\_index do |letter,x|  
@points[[x,y]] = letter  
end  
end  
end  
def solve  
@words.each { |word| search(word) }  
end  
def printWordsearch  
@rows.each\_with\_index do |row,y|  
row.split(//).each\_with\_index do |letter,x|  
print @letterPositions.include?([x,y]) ? letter : “+”  
end  
puts  
end  
end

def search(word)  
points(word[0].chr).each do |point|

possiblePoints = [point]  
point2 = point  
for i in (1…word.length)  
if checkNext(point2,word[i].chr,direction) or word[i].chr ==  
“_"  
or @points[(point2.to\_p + direction.to\_p).to\_a] == "_” # wildcard  
character  
= \*  
possiblePoints.push((point2 = (point2.to\_p +

wordsearch = “”  
loop do  
row = gets.chomp  
wordsearch += row + “\n”

end  
words = gets.chomp.split(/\s\*,\s\*/).map { |word|

w = Wordsearch.new(wordsearch.upcase,words)

w.solve  
w.printWordsearch
