The adjective must agree with the neuter noun; "spannende" would be wrong here.

Cultural Tip
In German, "echt" is a casual intensifier often used among friends or in informal settings. In formal writing you would replace it with "wirklich" or "sehr". Also, note that "Rätsel" is neuter, so the article and adjective endings must match the neuter gender (ein …‑es Rätsel).
