The Hints and Hijinx system is a purpose-built solo mystery system that's easy to design mystery games for, & puts the power of deduction in the hands of the player!

This is done by a clue gathering mechanic, where the player needs to overcome a challenge or complication with one of their skills at thirteen different locations. On failures, their skill’s dice rating can degrade, making finding future clues more difficult.

After their investigation is complete, the clues they gathered are used to make a hypothesis. The more clues the player can string together to create their hypothesis, the larger the dice they roll to see if their character’s hypothesis is correct. On a 5+ die roll, their deductions are correct and the mystery solved!

Like Choose Your Own Adventure books of yore, the goal of Hints and Hijinx is to provide a structure that players can be familiar with to go on a myriad of mystery adventures. When a player sees the Hints and Hijinx logo, they take comfort in knowing how to play, coupled with the excitement of new mysteries and the twists of each game.
