Welcome to Chom Isis, the game where you protect your own Pawns while trying to ruin the lives of other people's Pawns. A selection of people in the general public are selected by Chom Isis to become Pawns. These Pawns are living their lives without any idea that they are Chom Isis Pawns. As a Player, you will spend resources to keep your Pawns happy while making Pawns protected by other players miserable. The happier your Pawns are, the more resources you get to use in Chom Isis. Happiness is shown with a coloured box, white is very happy, green is happy, yellow is satisfied, orange is unhappy and dark red is suicidal.

Pawns are the playing pieces in the game. Each Pawn has a number of Deviants, which is a description of the main points of their personality. Example Deviants are Technophile (a gadget obsessed person) and Home Lover (who loves nights in with a cup of cocoa). A Pawn's Deviant can't be changed any more than a leopard can change his spots. Each Deviant has a strength associated with it, white is a Deviant which is important to the Pawn and red is less important (with gradients inbetween). If a Pawn does not have a particular Deviant then that subject is not important to them. A Pawn with two green Deviants is a generally very happy Pawn and is easy to please. A Pawn with two red Deviants is very difficult to please.

The Pawn's happiness is based on their Deviants and Life Inputs. A Life Input is a facet of the Pawn's life. For example, having a job is a Life Input. Having a spouse is another. To be happy, a Pawn must have Life Inputs that correspond with one of their Deviants. Therefore, a spouse Life Input corresponds to a Romantic Deviant but not a Technophile Deviant. Why would a Technophile want a spouse? Some Life Inputs are important to more than one Deviant. For example, a holiday home would excite both the Home Lover and a Materialist Deviants. Life Inputs can be unique, in that a Pawn can only have one of that type, such as a spouse. Unlike Deviants, Life Inputs can be upgraded by clicking on the name (see the jobs section). A description of all the Deviants and Life Inputs can be found in the reference section.

It is very difficult to win Chom Isis on your own. Chom Isis provides an Alliances to help join forces. Alliances have their own pot of cash which members can request to help pay for jobs. Alliances also allow members to propose jobs against Pawns anonymously, allowing you to not give away which Pawns are yours.

Information in Chom Isis is power. Your Intelligence screen allows you to collect information on Pawns and then this intelligence can then be used to reduce the cost of Jobs on that pawn. For example, if you know where the Pawn lives and what sort of things they like, an Operatives can more easily ruin their life. Each piece of knowledge about a Pawn is called a Nugget.
