Features & Capabilities

Random Balls - Shake Them! uses physics-based ball machines driven by your device's accelerometer to generate random numbers. Balls bounce, collide, and travel to target points to become your results. You can combine multiple machines—up to 20 balls per machine and up to 10 machines—so you can craft varied random sequences.

Shake or rotate your phone to mix the balls, then hold it upright to reveal the final results. These results are intended for reference and exploration, not cryptographic randomness.

User Reviews

Random Balls - Shake Them! is generally well-liked as a fun, innovative tool for generating lottery-style numbers, with enthusiastic recommendations and praise for its concept. A common critique centers on the limited base number pool and the need to pay for larger ranges, along with requests for more customization and stronger mixing features. Overall, users see strong value but want more flexible ranges and better hardware-like mixing options.

Pros

Innovative, physics-based approach to randomness that audiences find engaging, especially for lottery-number generation.
Strong usefulness for lottery number generation and overall positive reception among users.
Full version unlocks the complete range of numbers, aligning with user expectations and recommendations to upgrade.

Cons

Limited base number pool without upgrading; larger number ranges require payment, which many users note.
Pay-to-unlock extra numbers frustrates users who have already purchased the app.
Requests for more customization and better mixing (e.g., additional chambers, larger circle, and more dials) appear in multiple reviews.

I really like the app, but please make an option for free fall to have one section instead of being forced to have two

Random Balls-Shake Them! has completely changed the way I approach generating random numbers. As a frequent user of lottery number generators, I was amazed by the unique concept and execution of this app. The use of physics-based ball machines and real-world accelerometer data to simulate randomness is truly innovative and adds a level of excitement to the process. Each ball machine is thoughtfully designed and adds its own twist to the user experience. The ability to generate up to 20 random balls from a pool of 100, and even group multiple machines together, offers incredible versatility. The app's intuitive interface and engaging visuals make it easy and enjoyable to use. The developer has clearly put a lot of effort into ensuring high-quality randomness in the generated ball combinations, which is essential for any application in this space. Overall, I am beyond impressed with Random Balls-Shake Them! and have already recommended it to several friends. If you're looking for a fresh and entertaining approach to generating random numbers, this app is definitely worth a try!
