Some regular levels have secret objectives. Completing these objectives reveals hidden Kevin levels on the World Map.

There are 18 hidden levels in total: 8 in the base game, 1 in Surf 'n' Turf, 3 in Campfire Cook Off, 3 in Night of the Hangry Horde, and 3 in Carnival of Chaos.


If a level can unlock a hidden Kevin level, the top of its flagpole will be blinking white. See the image above.


Serving dishes in the correct order (as they appear at the top of the screen from left to right) increases your combo counter. Letting an order's time run out or serving something out of order resets it to 0. In short, to get a combo of X, you need to serve X dishes in a row in the correct order without failing.
