- Coinables published a web tool, Mnemonic Slots, that generates 12-word seed phrases and checks the corresponding Bitcoin addresses for balance.
- 12-word seed phrases drawn from the BIP39 list produce 2^128 (≈3.4×10^38) possible combinations.
- At two seconds per spin, a player could run about 16 million spins per year, yet the odds imply roughly 378,316,182,084,146,000,000,000 years to hit any address with funds.
- Newhedge data show about 57 million addresses hold BTC, with 52.6 million holding under 0.01 BTC (under $1,000), 3.4 million holding between 0.01 and 1 BTC, and over 144,000 addresses holding more than 10 BTC (about $910,000).
- The project’s site advertises *“Unlimited Free Spins = Unlimited Fun!”*, while the code repository’s readme states *“there are no winners.”*
GitHub user Coinables created a webpage, Mnemonic Slots, that randomly generates 12-word seed phrases, derives the corresponding Bitcoin addresses, and checks whether those addresses hold any BTC.
The site advertises “Unlimited Free Spins = Unlimited Fun!” and the codebase’s readme warns “there are no winners.” The tool uses 12-word seeds drawn from the BIP39 list, which contains 2,048 words and yields 2^128 (about 3.4×10^38) possible combinations.
A dedicated user spinning at two seconds per attempt could complete nearly 16 million spins in a year. Even at that rate, the published calculation shows it would take about 378,316,182,084,146,000,000,000 years to match the odds of hitting any funded address.
According to Newhedge, roughly 57 million Bitcoin addresses contain any BTC (addresses). The vast majority — about 52.6 million — hold less than 0.01 BTC (under $1,000). A further 3.4 million addresses hold between 0.01 and 1 BTC, and more than 144,000 addresses hold over 10 BTC (about $910,000).
A 12-word seed phrase is a human-readable sequence that encodes the private keys controlling associated Bitcoin addresses. The BIP39 list is the standardized set of words used to form such seed phrases.
The site asks “Someone’s got to win, why not you?” while the project repository reiterates “there are no winners.” For additional information, see the project page at Mnemonic Slots and the repository readme. Follow Protos on X, Bluesky, Google News, or subscribe on YouTube.
