Rules are very simple. Create words you see in the pictures using the appearing letters. If you see more than one picture, just make the words after each other without space. If the picture is big (bigger then its boundaries) use capital letters. If the picture is upside down, use the upside down letters. At certain levels you get some powerups. You can use the power-ups, when its icons in the left down corner is active. For the time-bonus, press 1, and you get some extra time. For the solution-bonus, press 2, and it reveals the solution of the whole level (only in normal-mode, in easy-mode the solution is always visible). For the letter-bonus, press 3, which elmininates all the letters not needed for the solution.
