"Halloween Riddles Mysterious Griddlers" is a basic Nonogram game... for those who never played one, it's a kind of grid-deduction-puzzle game, not unlike Minecraft or Sudoku. You're given a grid and a number of numerical clues. You must deduce where the safe places to click are. In a Nonogram, the correct clicks will reveal a small, obviously low resolution...
Halloween-themed "Griddler". Basically form pictures by coloring in the proper amount of squares... kind of like sudoku in a way. Decent enough.
