Freeware tile puzzle played on a 7 x 7 grid. All you have to do is to arrange the tiles to make a trail of the same color tiles from the Start to the End.(Not a Slider)
You can't even rotate them! Just move them to the correct square to make a Trail.
Sounds easy doesn't it?
Daves Trails was optimized for WinXP with a resolution of 1024 x 768 and above but should work just fine as low as 800 x 600.
Daves Trails runs in its own window which is scalable and you can even Minimize it so that you can do other things. (In other words, it won't Take Over your computer)
