Not a single ad between levels. Just pick easy medium or hard and you can play endless puzzles I love it!!!! Reminds me of older games when apps weren’t terrible. Miss the good old days! Thank you for this simple yet intricate masterpiece!!!!Suggestion: add a hint button and separate the music sound from the tapping sound effect. I like the tapping sound but wanna turn off the success sound. It’s nice to listen to music while playing this, that’s why

It’s cool that there is no timer and that there can be “loose” ends where most pipe games everything has to connect. The only reason I didn’t give it 5 stars is because it’s the same background, same color pipe same color “liquid”. If you could change the color of the background (I know you are trying to go simple but just the color itself would be cool) and the color of the liquid would be cool. For those that might have color issues make a toggle button that keeps it the same. But a red background with the pipe running a purple liquid would be cool or a yellow background with green liquid would liven up the game a bit.

No ads no time limit take your time and enjoy the game. If you need a challenge, move up from easy to moderate to hard levels. Nice to find a game you can play at your own pace.

Man, this game is awesome. Makes me feel like I’m back in 2013 before intrusive ads and in-app purchases became the norm.
