This isn’t a puzzle game, yet its being advertised as one. I even paid for this, because the ads were just too crazy terrible, and the first couple rounds were simple and fun. But once you get about 5 rounds in, it becomes apparent that the pieces spawn in a completely random (or worse, intentionally impossible) order that forces you to lose the round. A puzzle game provides a set round with a set way to solve it. You can even tell these rounds are just a random set of pieces because when you fail and start over, it’s an entirely different round!
It just gets insanely frustrating when you get far in a round, and then you’re presented 7 of the same piece in a row and you automatically lose, no matter how you played any others piece the entire rest of the game. There’s also no satisfaction to finishing one round, because it’s not like you managed to get the placement right, figured out the puzzle, get to move on to another one. Because like I said, even if you fail the round, you’re given a totally new one regardless of if you technically advance or not.
The ads in this game are as awful as everyone says. But the game itself is only $3, so if you enjoy it, I personally think that’s a very reasonable trade off to just pay for it. It’s not loaded with micro transactions or a monthly fee, just the one time $3. So if you can tolerate this to level 7 (just to be safe), just pay for it.
