Slick Picks is the next generation of sliding tile puzzles. Think (generic 3d puzzle with colors on the side) on a plane instead of in 3d. You don’t slide a single tile into an open space. Instead you slide an entire row or column which wraps around to the other side – move one tile into place, move three out of place.
3×3 and 4×4 puzzles are available free, along with 14 different pictures. A $.99 in game purchase unlocks the 5×5, 6×6, and 7×7 puzzles.
You may want to start with the number grid as you learn to solve the puzzle. Then move to the other pictures for a tougher challenge.
A note to the mathematically inclined and those who get frustrated putting the last piece in place: It is possible to flip the 15 and 16 pieces.
