*The button n.7 is...correct! Congrats!
In fact, the green button is now turned on and you can hear two beeps...but nothing happens...the huge trapdoor is still locked, but why?
After few seconds, something else appears at the opposite side of the table...a sort of black&gold treasure chest with some strange symbols on it...what to do now?

A new written on the touch screen table says: "Touch the symbol 4, thank you!"*
(p.s. Be careful, you don't have so much time to waste so guess it right at your first attempt possibly, if you push the wrong button, you will need to wait at least 3 hours to retry it...good luck!)
