Quick Make Change simulates the mental math cashiers do daily to quickly know how many coins and bill to return. With a 10 second or less time limit, players are always racing the clock in order to better their scores and unlock new levels. This is aimed at casual players who want to improve their mental math, as well as those who need sharp mental math skills for work.
While the first level allows a full 10 seconds to come up with the correct change, the harder levels shorten the time limit, increase the dollar values. The hardest level forces the player to calculate the change due themselves as well, creating a very difficult challenge.
