See Six is a fun game for light-fingered people who like a challenge.
Update 24 January 2019
We've added a tutorial so it's easier to understand the game.
From easy to very difficult in 4 levels with each 12 challenges. If you prefer to practice or just have some time to waste waiting for..., there is a "waste time" mode.
* Easy to play for anyone
* or difficult (at the highest levels)
* Good for your brain
* Improves brain/finger coordination
* Play in landscape or portrait mode
* Change tile size
* Could be addictive ;-)
* No ads and no in-game purchases, just like it should be
* Play "waste time" in the different level modes.
* Share your score
* Level 5: mix 'n match
* Level 6: play in the dark
