	tries = 1
	triesmax = 7
	guess = 0
end

	   print(devine un chiffre entre. [1 - 100, nombre entier])
		guess = io.read()
		guess = tonumber(guess)
		if guess == numb then
			print(Winner: Joueur)
			tries = triesmax

			 end
		 end
			tries = tries + 1
end

do
	term.clear()
	textutils.slowPrint(Tu peux relancer!)
end

Ty !

To print something to the screen, it has to be a string. To make a string, surround some words in quotation marks.

print( "Hello, World!" )

Also, your code doesn't have to be (and probably shouldn't be) surrounded by do … end statements. The do / end combination used with the while loop is necessary and serves a purpose, the other three do not.

Your program allows 7 not 6 tries, because 7 >= 7.
Also, you could use a for statement instead of a while statement:

for try = 1, 6 do
  <CODE>
end

I may be mistaken, but it looks like you have an extra end just before tries = tries + 1.
