The green numbered tiles add their tile value shown as an integer to your path score. Red tiles subtract their tile values from your path score. The goal is to configure a trip that has the highest score. On the first two legs (START to FINISH, FINISH back to START shown as blue and yellow paths), only horizontal and vertical moves of distance 1 are legal. On the final leg from START back to FINISH, only diagonal moves of distance 1 are legal (path shown in black). Tiles are added to the path by clicking the next available tile adjacent to the last tile in the path. At any given point in your journey, the legal tiles you can add to your path are shown as pulsating with a blue border around them. The path you choose cannot cross on itself. You can undo moves, replay a game, give the game a name and save it and later retrieve the saved game. Twenty five pre-loaded games of size 6 x 6 in increasing order of difficulty are provided in this limited free version. The full version available at the App Store allows any number of new fresh unique games to be created with grid sizes ranging up to 10 x 10. The "Solve" button lets the computer attempt to find an optimum solution to the puzzle. Then you can compare your score and solution path to the computers.
