DoubleFlip

A game of logic and concentration – solve the puzzle in the least number of steps or the shortest time.
A grid of tiles, each containing a flippable coin (with inverted color or pattern on the two sides), with an arrow indicating the direction of the flip (horizontal or vertical). When a coin is flipped (by tapping it) it will flip cause its two neighbors to flip with it (depending on the direction of the flip above-and-below for horizontal, left-and-right for vertical), AND also flips its (only its own) direction arrow, so next flip will be in the other direction.
Goal of the game: match all coins to its enclosing tile.
