Picture logic fans will love these colorful multi-layered puzzles. In each puzzle a photo has been separated into several color layers. Each layer contains number clues which you can follow to reconstruct the photo. Using logic similar to minesweeper, reveal parts of the picture, square by square and layer by layer. When all the layers are complete, they will be combined to reveal the entire picture, along with a quote related in some way to the picture. ******************** PRISMAPIX FEATURES Two free puzzlepacks 17 add-on puzzlepacks: small puzzles, giant puzzles, variety packs, themed packs. Easy, Tricky, and Expert playing modes. A special quote for every puzzle AutoComplete (or do-it-yourself) AutoScroll (or do-it-yourself) Two ways to mark squares - tap/double-tap or use the X/O play button. Pinch zoom to make squares fit your fingers. Optional sound effects iCloud support for your progress Universal ******************** SIMPLE RULES - COMPLEX PUZZLES - HIDDEN PICTURES Use number clues to figure out which pieces of the puzzle belong on each color layer. Paint the squares around each clue number so that the number of painted squares matches the clue number. With AutoComplete turned on the game will do some of the easy work for you. With AutoScroll turned ON the board will automatically slide to expose an area with useful clues. When there are no more useful clues on the current layer the game will switch to a different color layer. PrismaPix is based on the PC game "PrismaPix" by Kris Pixton and KpixGames. The underlying logic will be familiar to players of Minesweeper or Fillapix by Conceptis, but the prism-inspired separation of colors and multi-layered design take these puzzles to a new level.
