Jay Is Games Review

"Circulate executes everything with a simple sense of ease. Nothing feels too gimmicky, and new gameplay elements are introduced at a good pace and are utilized quite ingeniously. The variety of visual styles is also impressive, and it's fun to scope out the scenery even if you can't complete the stage to save your life. No fluff, just 100 odd levels of spinning, physics, and marble destruction. Quite a simple formula for fun!"

Out Of Eight PC Game Reviews

"Circulate certainly falls into the old cliché of easy to learn, hard to master. It's always nice to play something different than all those click management and match-3 games that populate the puzzle genre, and the rotational mechanics of Circulate certainly are just that. Circulate breathes some fresh air into a typically bland and repetitive genre."

CNET Review

"This colorful, unique puzzle game offers a number of stimulating brain-twisters. The basic gist of Circulate is this: you must rotate a sphere to rearrange similar-colored balls so they're all in one place. Each time you solve a puzzle, you're awarded a number of points that allow you to skip over easier levels. Every level has a different-themed board with pleasant graphics. Puzzle fans who like variety should certainly take a look at Circulate!"
