You can increase your Help Request limit by adding more Facebook friends to your Chef Circle.

All players are granted 3 Help Requests per day. As your Facebook Friends count and Referred Friend count increases in the game, you will see an increment in these requests. These increments happen when Facebook Friends count added with Referred Friend count cross certain thresholds.

You can tap the ‘Refer Friend’ button in Chef Circle UI to refer your Friends. And your Friends have to accept the invite and start playing Star Chef 2 for your counts to increment within the game.

However, please note the existing players in the game who you might have added as your Friend (by visiting their restaurant) will NOT be considered while calculating these thresholds.
