Our games are designed for ages 14 and up.

This reflects the difficulty of the puzzles and clues, as well as some mature themes (including murder!).

However, we follow the conventions of cosy crime, so our games do not involve any graphic or explicit content.

We include difficulty ratings on all of our games, scored out of 5.

• The Vanishing Professor Vanderkopf: 2.5 / 5
• The Death of Countess Cornelia: 2.5 / 5
• Christmas Eve in Little Smithering: 3 / 5

You can find Hints & Solutions online (the introduction to the games will provide the web addresses you need). 

3 - 4 layers of hints are provided for each clue, so you can decide how much help you want without giving the game away.

You may want to look-up one or two things online, check the hints, and read the ‘Big Reveal’. Otherwise, the games provide a welcome break from screens. 

Our games are set in the 1920s and 1930s, the Golden Age of Detective Fiction – bringing old-fashioned glamour to life.
