The user can select a game with 4, 16, 36, or 64 tiles.  Depending on the user selected mode the tiles will conceal either numbers or drawings.  After selecting a game size (2x2, 4x4, 6x6 or 8x8) and type (numbers or drawings), the user can then “riffle” the tiles (flip the tiles over temporarily) and then proceed to try to match the drawings/numbers in pairs that are hidden underneath the tiles.  Score is kept for each game size.

Test your short term memory for numbers or drawings.  Can you get a perfect score?  Riffle is a memory puzzle that allows you to choose your puzzle style and difficulty.  Pick numbers if you’re feeling analytical or drawings if you’re feeling intuitive.  Puzzles range from the very easy to the nearly impossible.  Riffle through the tiles to see what’s underneath, then see if you can find the matching tiles by clicking on each in turn.
