Gold Star Rankings
After you've completed a given puzzle, you'll be awarded a Silver Star on the puzzle selection screen to indicate your success. However, you can get a higher ranking. Retrying the same puzzle activates Advance Mode, which is a bonus challenge. You have to beat the same level three times in a row, and with different objects each time. If you restart, you'll have to begin the challenge from the beginning. If you successfully complete the Advance Mode version of a puzzle, you'll be awarded a Gold Star on the selection screen.
Gold Stars: Complete a level, then retry it to activate Advance Mode. Complete Advance Mode.
Merits are awards/achievments you can earn by doing different things in a given level. However, you need to complete the level in order to get them.

5th Cell Staff Room
If you're playing through one of the Challenge Mode puzzles, try summoning a teleporter. If you use it, you'll be sent to to the Scribblenauts staff room. The room includes the symbol for the 5th Cell development team, as well as several avatars for game designers.
Hidden space level
If you spawn a teleporter at the title screen and use it, it takes you to a secret moon level with aliens and a shuttle.
Easy Advanced Mode
The game ignores adjectives you try to put when writing any word, so writing "Small Hat" or "Big Hat" will only be recognized as "Hat", and will spawn the same thing. The exploit is in the fact that during Advanced Mode, the game will NOT accuse "same word" if you type an adjective before the word itself, eventhough the exact same thing is spawned. You can clear a stage three times by typing "Wings" the first time, "Big Wings" the second time and "Small Wings" the third time, you'll simply get the Wings all three times, but the game will register 3 different words and will allow it. If you're feeling lazy, you don't even have to put in a proper adjective, since the game doesn't recognize them, simply typing "aaa Wings" will register as "Wings", the game ignores the "aaa" as an Adjective (even if it really isn't one).
