Let players buy ten upgrades at once when each one costs more

In a clicker, every machine you build costs a bit more than the last, and players want a "buy as many as I can" button. A shortcut formula tells them they can afford one more than the shop will actually sell. This entry makes the button and the price shown agree to the last coin.

Why this works

A shop charges for real things, one at a time, in whole coins. A shortcut that adds up an ideal curve answers a different question than the till does. Pricing the button by walking through the same single prices that take the money means the label and the bill can never disagree.

When not to use it

Do not walk through prices one by one when the count is enormous, as in a late stage that buys millions at a time. There a clean approximation with a short correction is faster, and the player cannot tell a coin from the exact figure.
