4 stars: Exactly what it says on the tin. By far what seems to me like the most polished and least annoying of water sort games. I prefer playing offline to avoid unprompted (and unwelcome) ads, but I'll watch one for the extra cup when I get very annoyed at a harder puzzle. Fairly relaxing and challenging enough to get the mental gears spinning. Not 5 stars because... wifi being on means an ad pretty much every board.
3 stars: Fun game! The only reason why I'm not giving 5 stars is because there's something wrong with the saving. I play several levels and exit the game only to find that none of my progress is saved and I have to play the levels again. Sometimes this happens multiple times and I can't progress through the levels! This is very frustrating!
3 stars: The game is fun, but too glitchy. At some point, it reset on me so I've started over. Right now, the annoyance is that the colored cup lids over each cup are not showing up, so I'm not able to tell what color has to go in the cup. They look like all of the other cups. Pretty annoying.
2 stars: There's a glitch with level 303. Even though all the colors are sorted the bottles on the lower row don't get capped so you can't advance because the game thinks you haven't finished the level.
