Escape Mail is a family friendly adventure (all content is PG). The difficulty of Escape Mail is suitable for anyone 10 years or older, but playing with an adult is recommended for anyone under the age of 14.
There are 2 difficulties to choose from as well (Standard & Expert). Unless you have solved many escape room games before, or you're a sucker for punishment, we recommend starting with the Standard difficulty.
There is access to tiered hints online. Regardless of the difficulty level you choose, you can always access multiple hints (and the solution) with every puzzle along the way.
