Small jelly. Clever shots. That satisfying moment when it all clicks. Pull back, aim and let go. JellySling turns a simple sling into a physics puzzle where your angle, your power and your next move all matter. Collect the required stars, find a way around the obstacles and guide your jelly into the exit before your shots run out. MAKE EVERY SHOT COUNT A small change in angle can change the whole route. Use rebounds, plan ahead and work out how to reach that awkward star. Clear the easy ones, then rethink your approach when the next puzzle pushes back. FIND THE WAY THROUGH Walls, keys and locked paths give you more to think about than a straight shot. Look at the whole board before you launch: the shortest route is not always the one you need. A FRESH DAILY CHALLENGE Step away from the regular levels and try the daily puzzle. A new layout gives you another reason to come back and test an idea. PICK YOUR JELLY Start with two available characters and unlock more looks with stars. Find a favorite and make it your little puzzle partner. CLIMB BY LEVEL The world leaderboard compares your highest completed normal level. Progress is submitted automatically with an iCloud account, so you can focus on the next puzzle. Ready to find your angle? Your first jelly is waiting. JellySling contains ads and optional in-app purchases, including star packs. Online leaderboards require an internet connection and an iCloud account.
