SatoshiBall is a free Android application that gives you a chance to win fractional Bitcoin, known as Satoshi, every week. Developed by SatoshiSweeps LLC, this app falls under the category of Business & Productivity with a subcategory of Finance.

To play SatoshiBall, you need to pick 5 numbers and your SatoshiBall and submit your entry. Every entry you submit, along with all other players, increases the jackpot. The larger the pool of entries, the larger the pool of Satoshi we give away every week.

One of the best features of the app is that you get a free entry every day just for coming back. You can also build your referral network to earn an additional free entry every day for every friend who plays. Additionally, you can take offers to earn more entries to win. The drawing occurs on a weekly basis.

Overall, SatoshiBall is a great app for those who want to try their luck and win some free Satoshi. The app is easy to use and navigate, and the process of picking your numbers and SatoshiBall is simple. The referral program is a nice touch and offers an additional way to earn free entries.
