Mistress Maddison

One spin. Your Domme builds the board — from a range, or amount by amount, in any order, and any value can appear more than once. Repeated faces split that value's existing chance, so copies never secretly boost its total odds. The wheel can still be rigged from Gentle to Shark — and that level may be kept hidden. Wherever it lands is what you owe: no second chances once it's spinning.
