Guide For Fruit Ninja

You don't need to buy starfruit with real money
Starfruit is the main currency type in fruit ninja and you can use it to buy boosts and other swag inside the game. Fruit Ninja is one of the very few games that actually requires you to buy in-game currency in order to advance. Most of the objectives are fairly easy to complete and earn you quite a bit of starfruit. You can also watch short video ads which is another super simple way to rack up starfruit to use toward boosts. Don't use long swipes when bombs are around While bombs don't end the game in arcade mode, they do end the game in classic mode if you hit one. Try to always use short and brief swipes when you know bombs are floating around. The longer the swipe you use, the more likely you are to hit a bomb that may appear. Just go after fruit and don't worry about combos unless there are no bombs lurking around.
Check Gutsu's Cart periodically for free starfruit
Sometimes Gatsu has a nice little starfruit bonus waiting for you when you visit his cart. If you've never visited it before, be sure you do and you may be surprised how much starfruit he has to offer you right off the bat. This is also where you'll buy power ups to use inside the game, some of which you'll need in order to complete certain objectives. Use Peachy Times to boost your score in arcade and zen mod I've found Peachy Times to be one of the most useful power ups if you enjoy playing arcade mode. Every peach you slice gives you an extra 2 seconds on the clock. While that doesn't seem like a lot, when you swipe several of them, that's a heck of a lot more game play time to work with. In some games, it can make a difference of a few hundred points if you've got a great combo blitz going.
Don't use more than one finger
There are some tip guides out there that tell you that using more than one finger is a good idea. I have never ever found this to be effective, and if anything, I've found it distracting. All it does is obscure your view of the screen even more. Lay your iPhone or iPad down on a flat surface if you can and find a position that allows you to see as much screen as possible. Try playing upside down Playing upside down helps some players since the fruit comes up from the bottom. When you're holding your iPhone or iPad, your hand most likely obscures some of your view of the bottom of the screen. Playing upside down prevents this from happening. If you play with your phone laying flat on the table, simply rotate it. If you play holding your device, use rotation lock and then turn it.
Multiple special bananas = huge high score
The most awesome way to boost your score ever is when you get a two power up bananas at the same time in arcade mode. Double points and freeze are awesome but the rare fruit frenzy and freeze bananas are by far the best combo to have. Once everything is frozen and the fruit is moving in slow motion, just wait for it to fill up then slide in broad strokes to rack up huge combos over and over. A good ninja always listens first, and acts second If you pay close attention, you can hear whether fruit or a bomb has been launched your way by the sounds the game makes. Listen to these cues as it gives your brain time to prepare for what's coming up from the bottom of the screen. If you hear a ticking bomb, you know that short strokes are a good idea. If you don't, you know you're in the clear to swipe as many combos as you can quickly.
Pay attention to the objectives and complete them
Completing objectives in Fruit Ninja is the simplest way to rack up starfruit quickly. The amount offered is very generous and the objectives are never incredibly hard. Some of them may require you to buy power ups to complete them but they don't cost a ton and they're extremely fun to use. I also never pay to skip an objective. It costs a lot of starfruit and odds are, you'll get good enough to pass it if you just try a few times. Don't be afraid to start a level over Sometimes you start off badly.
