Tips & Strategies for High Scores
Mastering Flip Reflex requires practice and understanding of the game mechanics. Here are some expert tips that will help you achieve higher scores and improve your overall gameplay experience. These strategies have been compiled from extensive playtesting and player feedback.
- Hold your phone loosely but securely - a death grip slows you down
- Practice the flip motion a few times before playing seriously
- Use a smooth rotating motion, not a jerky flip
- Keep your wrist relaxed for faster movement
- Anticipate the signal but dont flip early - that causes a false start!
- Make sure you have enough clearance around you
- The flip needs to be complete - screen should briefly face down
- Return to starting position quickly for the best time
Remember, improvement comes with practice. Don't be discouraged if you don't achieve high scores immediately. Each playthrough helps you understand the game's nuances better and develop muscle memory for quicker reactions.
Technical Information
This game uses the DeviceOrientation API to detect when your phone is flipped. The beta value (front-to-back tilt) changes from near 0 (screen up) to near 180 or -180 (screen down) when you flip the phone. The game monitors this transition and measures the time from when the prompt appears to when a valid flip is detected and the phone returns to the upright position.
API Used
DeviceOrientation Browser Support
Chrome, Safari, Firefox, Edge (latest versions)
Device Requirements
Mobile device with gyroscope/accelerometer sensors. iOS 13+ requires explicit permission.
Frequently Asked Questions
What counts as a valid flip?
A valid flip requires the phone to rotate past 120 degrees (screen pointing mostly down), then return to roughly upright (within 30 degrees of starting position). Quick partial flips don't count.
Why did I get a false start?
A false start occurs if you begin flipping before the 'FLIP NOW!' prompt appears. The game detects significant movement before the signal and penalizes early reactions.
What's a good reaction time?
Average reaction times are 400-600ms. Anything under 300ms is excellent. Under 200ms is exceptional and might indicate you anticipated the signal.
Will flipping damage my phone?
The game is designed for controlled rotation, not throwing. As long as you maintain a grip on your phone and flip it like you're showing someone the back, there's no risk of damage.
Can I practice the flip without playing?
Yes! Before starting a round, you can practice the flip motion. The sensor indicator will show if your flip is being detected correctly.
