Playfish is offering Restaurant City users an added incentive to play their popular restaurant simulation game every day. Since the update launched, the first day a user logs into the game, they will be rewarded with one free ingredient to be used in-game. If they come back the very next day (the second day), they will receive two free ingredients. Finally, if the user comes back on a third consecutive day, they will receive three free ingredients.
Unfortunately, the bonus tops out at three ingredients per day, but the time period for earning said bonuses seems to be limitless. So long as you continue to login to the game once a day, you’ll continue to receive your bonuses.
Intuitively, then, if you miss a day, the cycle resets and you’ll start again at earning a single ingredient in a day.
