A new take on Bix Challenge, the line-drawing arcade classic in the spirit of Qix, Xonix and JezzBall. Draw lines to cut the field, fill it with light and trap the bouncing balls. One rule to master: when you close a line, the side with fewer balls fills up. Easy to learn, fiendishly hard to master. WHAT'S INSIDE • 100 levels across 10 galaxies, each with its own twist: ball traps, line limits, dark zones, time trials, giant balls, ice walls and hunters • The Rift: beat level 100 and a hidden climb opens. How high can you go? • Three stars to earn on every level, chests to open, gold balls to collect • Boosters when you need a hand: Slow start and Shield • Glowing visuals made for today's iPhone and iPad • The original soundtrack, now opening up as you fill the field • Your progress is saved in iCloud and follows you to your other devices • Plays offline THE ORIGINAL, STILL HERE Bix Challenge has been played by over a million people since 2008, reaching #2 in France, #3 in Germany and #4 in the UK. The classic version is still in the app, exactly as you remember it: turn on "Classic version" in Settings.

Verdict
The clearest difference is rating: Circle at 4.3 against Bix Challenge's 3.4. Circle also leads on ratings volume (5.5K vs 25) and iOS requirement (12.0 vs 16.0). Bix Challenge's advantage is ads (none vs shown) and review sentiment (75% vs 43%). On price, in-app purchases, monetization model and device support there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. Bix Challenge sells 10 one-off in-app purchases and Circle sells 5 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.
Circle holds the better App Store score, 4.3 against 3.4. That said, the two scores are not equally well evidenced: Circle has 5.5K ratings behind it against 25, so its average is the more settled of the two. Written reviews complicate that: 75% of Bix Challenge's written reviews are positive against 43% of Circle's, so the app with the better star average is not the one people write more warmly about.
Bix Challenge ships an update every 11 days, Circle every 2 months. The most recent releases landed on November 1, 2026 and November 3, 2026 respectively.
