Choose a stake and press Start Burger. The chef puts down the bottom bun, then you add ingredients one at a time. Every ingredient that lands without the stack falling raises the burger's value.
Sell at any time after the first ingredient to get stake × current multiplier. If the burger falls before you sell, the chef is fired and the stake is lost.
Ingredients come in a fixed order and each one moves you one rung up the ladder. Finish all 12 for a Perfect Burger at x100, which sells automatically.
Pick any ingredient each turn. Its multiplier is applied to the current burger value. Bigger multipliers are harder to balance, and each ingredient is in limited supply. The plate holds 12 ingredients and the maximum win is x5,000; either one sells the burger automatically.
The first ingredient of a Chef's Choice burger carries a slightly higher drop risk. After that, the drop risk for every ingredient is 1 − 1/multiplier.
Both modes return 97% of stakes, whatever ingredients you pick and whenever you sell. Every drop is decided by a random number generator before the ingredient is placed; the wobble only plays that result out.
