After being entrusted by Mr. Krabs to keep the Krabby Pattyformula safe, SpongeBob is overcome with grief for losing the recipe. He then relies on the help of the most unlikely companion, Plankton, who wants the secret Krabby Patty recipe for himself. With the help of his friends, SpongeBob must use Plankton's memory machine to retrace the happiest moments of his life to find the Krabby Patty formula in time for the Krusty Krab's Eleventy-Seventh Anniversary.
The Spinner: The player clicks and holds the handle, and keeps moving the mouse up and down to crank it up. There's also the Auto-Spin selection.
In the upper left corner of the screen, the first number shows how many tiles the player can flip, while the second one shows how many moves the player has.
The player, instead of flipping tiles, can turn them into moves by clicking on "FLIPS INTO MOVES" in the upper left corner. The player can turn his/her moves into Happiness ("Happy Points", by clicking on "MOVES INTO HAPPINESS". His/her moves don't carry him/her over to his/her next turn.
If Grease is oozing out of the Spinner, all the tiles the player flips are slippery.
The Camera: The player moves his/her cursor towards the edge of the screen to move the camera and uses the mouse wheel to zoom in or out.
The Tiles: The tills the player can flip are highlighted and he/she has to click to flip.
The arrows around the player's character tell him/her where he/she can move. The player has to click on an arrow to move in that direction. He/She can also use the arrows keys on the keyboard.
Happiness: The yellow bars at the bottom of the screen, near the player's character, are the "Happiness" meter. It increases a bit every time the player does something that makes his/her character happy, like flipping tiles or sliding! Happiness is the game's currency: It is used to buy Gizmos and unlock Happiest Moments.
Happiest Moments: A number of Happiest Moments that the player sets at the beginning of the game, unlock automatically every time the "card" meter is full. The player has to collect all his/her happiest moments, to make the exit tile appear.
Games: If the player wins one, he\she earns a Happiest Moment. If he/she loses one, his/her Happiest Moment lands somewhere on the board. There are three kinds of mini-games:
Games triggered by landing on the "Gift" tiles on the board.
The Gift Games allow everyone to get competitive and earn Happiness. Everyone earns some, but the player earns a lot more if he/she wins.
The "Star" game on the Spinner
The Star Game on the Spinner is called as a "surprise".
The Happiest Moment games triggered when the "Card" meter is full
The Card Meter Games are the games the player plays automatically when he/she has amassed enough Happiness ("Happy Points").
Gizmos: Once per turn, the player can buy a Gizmo, if he/she has enough Happiness. The number of yellow bars below the Gizmo is its cost. Each Gizmo has a different effect. The player selects a Gizmo, clicks the "Green Check", then sets it on the board, or clicks the red "X" if he/she would rather buy a Gizmo later.
Winning: Once the player has collected all his/her Happiest Memories, heads for the "EXIT" tile to win the game.
