"I've been playing it since it came out almost six years ago when it only had 85 lil' levels. It's pretty, puzzley, and is the perfect thing to do with your hands while watching TV." —Maitland Quitmeyer
"It’s constantly adding new mechanics, but here’s the big thing: during the Coronavirus crisis, they’ve been constantly giving away hours of free lives, so you can just keep playing. When I was on bedrest with my last pregnancy, this was one of the games I actually paid money to continue, and they’re just trying to help by giving away lives." —rachelolsonw
"It’s a color-matching game but has a ton of different obstacles, which are introduced as you level up. If you are bored of that component of the game, they also feature between two to three different mini challenges, which are all very different than the main game to keep it diverse. It’s very relaxing and aesthetically pleasing." —cdpatterson92
"There's a sort of companion game from the same company called Dots & Co that's also really good." —calyma
