Ball sort puzzle for iPhone and Android
Tap a tube, then another, to move the top ball. A level is solved when every tube holds one color. In a duel, you and the other player start the same board at the same moment, and the faster time wins.
Every player gets the same 2,000 boards in the same order, so a score on level 40 means the same for you as for anyone on the leaderboard. A solver built and checked each board: every one has a solution, and the game knows the shortest. The server replays your moves before a score counts.
Send a friend a six-character code, and you both start the same board together, each watching the other’s board in miniature. QUICK DUEL finds someone online within 10 levels of yours; if nobody turns up in 10 seconds, you race a recorded run by a real player on that board. Paying gives no edge in a duel.
All 2,000 levels are on your phone and play without a connection. Leaderboards and duels need the internet.
