There are several types of resources in the game:

Energy — a resource that allows you to start levels.

One unit of energy is restored every five minutes. It can also be replenished for free by watching ads or purchased in the in-game store.

Please note: if you leave a level without completing it, the energy spent will not be returned.

Currency — the main currency of the game.

Currency can be earned by completing levels or purchased in the store.

Bucks are needed to purchase restaurant upgrades.

Experience Stars are given for upgrading restaurants. Each upgrade grants 5 stars.

Yellow Stars are given for each restaurant upgrade. These stars are required to unlock the next restaurant.
