## Why: the goal or problem

Hints are spent one at a time. A permanent unlock cannot express a balance that decreases and can be replenished.

## How: work toward a solution

A fictional puzzle app starts with zero hints. Buy three, then use hints repeatedly: the balance falls to zero and further use is blocked. Buying another pack adds three again. This is a local simulation; no purchase is processed. Prices, taxes, fees and refunds are omitted. Reset or reload clears the example.

## What: the concept

A consumable purchase supplies units that are depleted through use and can be bought again. It differs from a non-consumable feature entitlement.

Combine with free access while making balance and spending clear.
