25 or 6 to 4

"25 or 6 to 4" is a big hit from Chicago Transit Authority (they call themselves "a rock and roll band with horns") from their second album, released in 1970, where they shortened the group's name to just Chicago. They're still going strong, and their 37th album, "Chicago XXXVII Christmas Songs" was released in 2019.
This is probably the 'loudest' song they've ever done, but they've had plenty of hits over the years, including "Does Anybody Really Know What Time It Is?", "Saturday in the Park", "If You Leave Me Now", "Feeling Stronger Every Day", "Along Comes A Woman" and more.
People have wondered about the title, thinking it may be drug related or some kind of code, but according to Robert Lamm (who wrote it), he was up late one night, trying to put together a song, when inspiration struck at 25 or 26 minutes before 4 a.m.

Relaxing logic level with nice ending step "breaking the wall" & desogn...Thanks for sharing @D.S.Masters

Relaxing fun, as always, . It's a bright sunny day here (first in a long time!!!), so my screen was looking rather dim even with the brightness turned up full. I just bumbled around in the dark and pushed the balls and it all worked out, ! Great fun, thank you!

Enjoyed level, the ending came earlier than I expected. Thanks for sharing.

@delator77 As you can imagine,getting that wall to be stable took a bit of work - worth it in the end.

Another fun one. Played it a second time to get a better look at the ending action.

@Don G Rowe That's one of those things where you test it again and again, making sure that it works every time... then you post it up, and decide to play through it again, and it fails. Oy! I'll settle for it working 90% of the time.

@D.S.Masters It worked every time.

Spoiler

I just had to spin the level around after knocking down the final ball to see the section getting pushed out.
