Pro tip: turn off WiFi while playing

This game is just puzzling enough after a certain point, but then it just repeats levels. I’m at Level 1048 and I had that feeling of “I’m sure I passed that tree 5 times now”. However, it makes up for lack of puzzles with a building mini-game.

Why did it take me so long? Because the puzzles are very addicting w/o ads. I kept going into a trance as I was solving them. The puzzles are easy enough, but very satisfying to solve, and the UI is pretty good.

So - obviously an addictive game. The weird little side game took me a couple of days to figure out what the point was but that’s neither here nor there. I just got to level 401 aaaaand there’s not enough spaces/too many blocks. I’m only a little more irritated than what might be rational because I haven’t had to use any skips but I won’t be able to finish this level 😤 Other than that, my rating is because, fairly often, despite swiping in a particular direction, the tiles will go in a direction of their own choosing, which means I have to restart. If the tiles could be more responsive, the little side game with the houses better explained, and the levels all have accurate tile to space ratios (again, it’s the first time in 400 levels but I’m a little more aggravated by it than I should be) I’d be cool upping my rating.

Relaxing game with too many ads

I like the game play. And the look and feel. There is room for improvement. And there are way too many ads. I would consider paying to get rid of the ads, but:

I got to level 486 and it appears to not be solvable. There are 25 blocks but only 23 spaces. Is there a secret trick or is it a bug? That’s annoying. Oh well, it’s a good reason to stop playing and get back to work.
