In the Memory Sweep game the player starts with a 4x4 grid where for a short time (12 seconds) the position of some bombs from the grid is shown. The player must memorize the position of the bombs and try to correctly click on them after. Guessing 5 in a row, the grid size increases by one to 5x5 (6x6 and so on). Also if we lose twice in the row the grid size decreases. In the second game, Perilous Path, the player starts with the same setup (4x4 grid) and the player must connect two given positions avoiding to click on bombs. The same rule for 5 guesses in a row applies here. During the entire game the player sees the number of guesses, how many correct answers he/she had, the percentage of these correct answers and also the maximum winning streak.
I started with the Memory Sweep game and after I came with the idea how to make it work I made a second one called Perilous Path, also from PEAK (http://www.peak.net/). The two games are in the same Scratch project called Memory Games.
