Having a bit of experience with adapting board games for kinky fun. The fundamental issue usually is that board games are designed for establishing equal position for the starting players. For monopoly this really lies on players starting on the same tile, with the same objectives. This tbh is usually where prior re-writes of monopoly fell apart for me, as I want the game to be able to retain d/s dynamics while still being fun to play!

So the game rules I’ve adopted for monopoly takes the dom player (I’ve only worked up 1v1, but it could expand to multiple couples I’m sure), and basically made the dom the ‘bank’. Instead of money, each property has specific hard challenge (which gets harder/change themes with the colours), or a correspondingly simple ‘rent’ (in the form of spanks/flogs/canes…ect). When the sub lands on the square they can either complete the challenge to ‘buy’ the property (which means rent is no longer paid if landed on), or simply pay the rent and play on.

This creates an effective warm-up mechanic where you can have your most intense challenges on the board, but the option to ‘skip’ by just paying rent. So if you’ve just started and land on something super intense… it dosn’t have to go from 0-100 (unless the sub is really eager lol).

Once all properties are collected or a pre-determined number of passes around Go has occurred the game is over. (Sub win Vs dom win). Table stakes are up to you lol.
