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.

Read full description

Paint national flags from clean line art. Choose a color, fill each stripe, cross, star, and emblem, and cover any miss with no penalty. Keep a sample on screen while you learn, or study the flag briefly and paint from memory. Clear countries by continent, light them in an atlas, and open a short card for the capital and a flag note. Labels and patterns help when shades are close. Fully offline. No account and no forced ads.
