Think as a Standard Verb

WONDER ABOUT … Could work.

Now that I think about it, THINK (without an object) could be a synonym for HINT if the hints were worded appropriately.

Alternatively, THINK with an object can be hints for a particular puzzle without cross referencing other unsolved puzzles, as well as confirming solutions for already solved puzzle. An example would be if you use an incorrect object to solve a puzzle, thus locking out the game.
