Almost perfect

I love this game soo much, it’s challenging and addicting. But I do feel frustrated because whenever I open the app, my music stops even if the sound is off in the game. But I really enjoy everything else! I am really so addicted to this app that I had to delete it to make myself take a break, and then I redownloaded it and a new thing “daily challenges” appeared and I loved it SOOO much. I again kept playing it so much that I made myself temporarily delete the app again. Then I redownloaded it and the daily challenges were gone! I want them back!!
Also I think the ads are overbearing.
But yes still 10/10

Love it!!!!

This game is really addictive and challenging. Very easy to understand and play. The only faults of the game are that once u place a tile u cannot move it even if u put it there by accident. Also you cannot see what tiles are coming up next nor can u flop the tile that you are wanting to place. Seems like once you place the set of 3 tiles the next tiles purposely come up against you to block you from making any realistic move. In any event this game is very challenging and maybe if you were able to do all things I just described it would be too easy. Thank you developer for this game!!!!👍

Missing something...

Others have mentioned the ads which I actually don’t have a problem with. It’s easy enough to skip them after a few seconds (you just have to know where to tap).

Where this game gives me pause is that any strategy is completely removed by the randomness of not knowing what set is coming next. You’re simply placing blocks and hoping that you’ll get blocks you can use. And, although I haven’t actually counted, there are many runs where it seems like I’m deliberately getting blocks which are the exact opposite of what I’ll need.

I agree with others that being able to rotate blocks would increase the level of strategy that seems to be missing from the game.
