Cube Connect

The game is great. There are lots of free levels and free puzzles every day. UPDATE 12/15/2023: Some time ago, ads started playing audio by default again. As the ads had a Mute button, I didn't downgrade my review. After the latest release, there is no Mute button, so you have to wait for the Skip button to appear. Ads also now seem to have three "stages" instead of two -- the video, a playable demo, and a page to get to the Play Store with a delay. Due to that, I'm dropping two stars.

Lots of fun! It's still 2D because the puzzle is on the surface of the cube, but these guys have implemented a really nice variation on the traditional Flow topology. The simple UI works well.

Really enjoyable. Challenging UPDATE 20/12/2023: After I paid to stop being distracted by adverts, it dawned on me that the Developers have stopped updating the game which is disappointing cause some were really good. The 6 sides is not playable yet cause you can't get a grip so you can draw a link or line from side to side. Not playable. Hopefully developers will update it with a solution!
