YAP stands for 'Yet Another Puzzle'. Yet another but quite cool - you can use your own images. The objective is simple - solve a puzzle as fast as you can. But the fun is real. If it seems too easy, try harder levels. You can select one of 10 built-in images to solve or copy own images to game folder and use them instead. You can select level - from easy where the image is divided into 3x3 tiles to hard 9x9 (a little less for Android). On Android you simply tap to select a tiles and slide it into different (possibly proper) place. When you move a tile into a new position the one that was there before swaps places with the moved one. When a tile is in its proper place you will notice a sound and golden flash. Note that tiles are not locked when they reach the right place, you have to develop a strategy to avoid unnecessary moves. Also there is in-game menu, with options to see an image preview and mark good or bad tiles for a while.
The game allows you to use your own images in png and jpg formats (based on file extension: png, jpg, jpe, jpeg). On Android simply put your images in a folder (depending what your external storage path is) something like /sdcard/noniewicz.com/yappuzzle/images. This folder is automatically created by the game and filled with game's built-in images. Please make sure that your images are not too big in size. Optimal / recomended image dimensions are 800x600 to 1024x768.
