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.

Reclaim the filled area avoiding the enemies. While you are in the perimeter you are safe, but you have to venture into the area and return to the border to reclaim it. If the enemies touch you or your line or you touch your own line you lost a life. If you liked classics like Qix or Gals Panic, you'll enjoy this game. There are two game modes: Arcade and Episodes. In the Arcade mode you will fight increasing number of enemies in three difficulty levels. In the Episodes mode you will need to solve 80 levels with different enemies of several kinds, on some levels you will not be safe in the perimeter! How to play: You just need to make gestures anywhere in the screen. If you want to go up, just touch the screen and swipe up, if you then want to change direction, just swipe in the desired direction. You can combine several gestures for an incredibly fluid experience. If you have a problem, please send an email to qanma.games@gmail.com to solve it.

Verdict
The clearest difference is price: Bix Challenge at Free against The Filling's $0.99. Bix Challenge also leads on review sentiment (75% vs 40%) and update cadence (every 8 days vs every 14 months). The Filling's advantage is rating (5.0 vs 3.0) and in-app purchases (none vs 10). On ratings volume, ads and device support there is nothing between them.
