3. Leave No Tile Untouched.

If you fail to follow these simple instructions, I will make fun of you. And even if you follow my instruction and beat the puzzle, I'll probably still make fun of you. However, if you manage to beat all 250 puzzles... yeah, odds are pretty good that I'll make fun of you.

So sit back, work your way through 250 handcrafted puzzles, and remember... Leave No Tile Untouched.
