Juego descifrar el código

[omar2886]

Gracias jcMouse! ya me he dado cuenta tras haber mas o menos acabado con el código.... .
Sé que es bastante cutre, pero es mi primera vez, aquí lo comparto a ver si alguien puede ayudarme a mejorarlo :

HTML

Código:

<script type="text/javascript">
function checkboxlimit(checkgroup, limit){
	var checkgroup=checkgroup
	var limit=limit
	for (var i=0; i<checkgroup.length; i++){
		checkgroup[i].onclick=function(){
		var checkedcount=0
		for (var i=0; i<checkgroup.length; i++)
			checkedcount+=(checkgroup[i].checked)? 1 : 0
		if (checkedcount>limit){
			alert("Vous pouvez choisir seulement "+limit+" ")
			this.checked=false
			}
		}
	}
}

</script>
