Flippy Bit And The Attack Of The Hexadecimals From Base 16 Hi We at Q42 have teamed up with Russian psychologist Kateryna Afinogenova to create this experiment to test her recent study in which a group of 420 kids were shown to have a natural talent for doing bitwise operations and conversions to hexadecimals. "Seven percent of the test group could bitshift" she said to Scientific World News in an exclusive interview, which caught our nerdy attention. Especially the following statement: "While adults have trouble with binary numbers, from around the age of two, children can not only calculate on a binary scale, but even translate from binary to hexadecimal - and back." We were able to contact her and collaborate remotely on this experimental game that allows kids to literally do that conversion. Afinogenova requested to omit a tutorial to further emphasize the adoption difficulty between adults and children. We were amazed by the results. You can be amazed too! Play the game and find out!

Brain Code holds the better App Store score, 4.6 against 4.3.

Written reviews complicate that: 88% of Flippy Bit & the Hexadecimals's written reviews are positive against 77% of Brain Code's, so the app with the better star average is not the one people write more warmly about.
Flippy Bit & the Hexadecimals ships an update every 96 months, Brain Code monthly. The most recent releases landed on October 23, 2026 and October 24, 2026 respectively.
