A game that one probably doesn't admit to owning in public. Monogamy is a two player game meant for committed couples to get to know each other better.
Some alcohol and your partner and you're ready to start. You move a playing piece around a board and land on squares which involve kissing, drinking, taking clothes off, or taking a card which asked the partner something about themselves or reveals something about you. Every time you complete the board once you move up a level and the questions, and the kissing become more intimate.
The game starts slow and warms up very nicely. Not at all tacky although it gets quite exciting at the end! It is really good to find an adult game not aimed at large numbers of drunken party-goers but at improving the romance and sex-life of a committed couple.
