The colors are vibrant, with pretty backgrounds and several different choices of tiles. The board moves as I remove tiles, making the remaining tiles bigger and easier to see and match up. The only downside I've found is that if I get down to the last tiles and can't remove them, the board reloads exactly as it was and I get to try again. I'd rather it shuffle the tiles and give me a new chance. However, that is a very small nitpick and most definitely has not kept me from playing the game late into the night when I'm supposed to be charging my phone. lol
The ad bar across the bottom is barely noticeable, and hasn't distracted me at all from playing.
