carols - true, but to avoid confusion and problem sif your names get more
complex (i.e. i think $$some_name will go crazy, you should always do it
like this

$var_name = "game1";
${$var_name}

cheers guys

// It´s very easy and to tell you the truth I descovered it by accident:
//
// Lets say you have a variable with the dynamic variable name
// (ej. $var_name =
// "game1";)
//
// if you want to create this variable ($game1) then you can write:
// $$var_name
// And that´s it.
//
// try it.
