We're happy to suggest some pointers that might help up your game!

In any episode that seems really difficult, one very effective trick is to use Special Guest (double coins) Prep Recipes that match the incoming customers - doubling your coins for every instance that matching character appears in that particular episode.

For example, if you see the customers Skip and Barb, a lot in a particular episode - then you'll want to equip Skip's Prep Recipe (Pork Chops) and Barb's Prep Recipe (Braised Carrots) beforehand.

By design, the last few episodes at the end of Season Four, no matter the venue, are intended to be very challenging indeed!

Try equipping Fast Flo (Trout Almondine) and two other Special Guest (double-coin) Prep Recipes that match the incoming customers in a particularly tough episode. 

Also, make sure you're swiping multiple tips instead of just tapping single tips - you get a bigger coin bonus when swiping multiple tips!
