Keep the path whole, or the ball slips off. Don't Slip Off is a zigzag ball game where you fix the path as you go. A ball rolls along a zigzag track of blocks, and some of those blocks are out of line. Swipe up or down to snap each one back into place before the ball gets there. If the ball reaches a gap, it falls and the run is over. HOW TO PLAY • Swipe up or down to move a block back into the path • Fix every gap before the ball reaches it • Score a point for every block you fix • The ball speeds up with every block you fix NEW BLOCKS AS YOU GO • Double-drop blocks sit twice as far out and take two swipes • Corner blocks can slip out of line too • Sinker blocks look fine, then drop out just as the ball gets close HARD MODE In Hard Mode the ball rolls faster, you have less time for each block, and the new blocks show up at half the score. COMPETE • Normal and Hard Mode leaderboards • 15 achievements to earn • Share your high score and challenge your friends to beat it PLAY OFFLINE No wifi needed. Don't Slip Off plays offline, so it's ready for flights, road trips and waiting rooms. Easy to learn, hard to master, and made for one finger. How far can you roll?
