Money is used to purchase various items in Plants vs. Zombies games. In most cases, money will drop under certain conditions, and the player must click on it, move the cursor over it, tap on it, have a Gold Magnet collect it to obtain it, or, in the PlayStation Vita version of Plants vs. Zombies, tilt the console, although it will sometimes be automatically added to the bank.
In PvZ, they are used to buy items from Crazy Dave’s Twiddydinkies. Before the shop is unlocked, it can be used to purchase seed slot upgrades directly from Crazy Dave, although the player can only have up to eight slots before the shop is unlocked after level 3-4.
In PvZ2, they are used to purchase in-game items Power Ups & Plant Food, as well as to upgrade plants & to replay lost Piñata Parties. Sometimes, a pinata may appear in the store for 5000 coins, in exchange for obtaining 15 or 20 plant seed packets. Community Challenge Rewards are also bought with coins.
