Well...

Tic tac toe: it helps to control the center and a corner.
Sudoku: remember if two numbers can fit only in the same two squares of a 3x3 interior square, the other numbers are ruled out by exception.

Oh, you meant puzzles in this game. If you start with a list of puzzles and their solutions, your gameplay will be reduced to dragging villagers around trying to perfect their skills, and watching ads to earn lavastones. Money can buy you out of the second but not the first. Anyway, it's a boring game if you eliminate the puzzles, since it is a puzzle game.

Give it a try, and ask for a hint, rather than a solution, when you get stuck. It's really a fun game!
