BlackFlip is an interesting puzzler where your mission is to flip over black and white tiles in order to tile the grid in one color. There are more than 6,000 different grids included in the game each with a different pattern, and a differing difficulty level, from one to five stars (with five being the most difficult).
I found the game a little frustrating at first because it's very difficult to work out exactly what you're supposed to be doing and there are no in-game instructions. After checking out the demo video on the developer's site and experimenting for a bit, I finally worked out the dynamics of the game.
BlackFlip actually proves to be quite engrossing after a while, and the thrill of turning an entire grid white becomes strangely compelling. With so many puzzles included and a Zoom facility to help you out, there's certainly plenty of life in this one. Unfortunately though, I felt some of the difficulty ratings were a bit odd, as some supposed five-star ones I finished very easily, while I puzzled over a few one-star games for ages.
The gameplay is a little convoluted, but once you get the hang of it, BlackFlip becomes an amusing way to pass some time.
