Medium was my first try and it was just right, for me and my tired brain tonight! ### 2/5 — Ads very annoying, earned avg 28 cents/mo *2024-05-20, version 3.0.0* Too many ads and not worth my time. Played daily and after 4 months I have $1.12 no way to know the conversion rate but you get less than a penny a day. ### 5/5 — Points redemption *2024-04-17, version 2.8.4* How do I redeem my points? I have over 12,000,000, but can’t seem to redeem them after switching to my iPhone. Any help would be great. ### 1/5 — No way to redeem *2024-04-02, version 2.8.4* No way to redeem point ### 1/5 — Waste of time *2024-04-01, version 2.8.4* I played 15 to 25 games daily for over two weeks which also meant watching a TON of ads. I earned over 1 million Bling points. I cashed them out and found the value was about 60 cents. I enjoy sudoku but I'm not interested in watching all of the ads and only earning 60 cents. Total waste of time. ### 1/5 — no BTC cashout *2024-03-28, version 2.8.4* It makes you watch advertisements for a minute between every game😤👎 and it doesn’t pay you Bitcoin. I would be okay to watch the ads if they pay me my sats as they promised/advertised. Sucks👎 ### 1/5 — Too Good To Be True *2024-03-15, version 2.8.4* This game promises you BTC for playing Sudoku and watching ads, but they actually won’t let you redeem your coins for Bitcoin. I was constantly trying to redeem my points for Bitcoin via Coinbase but there was always a rejection. I then read in Bling’s terms of service and it says they ‘try our best to payout the Bitcoin’. That means they don’t have to. This app is just another scam, you might as well work another couple hours a week at your job and buy $20 of Bitcoin every week. ### 2/5 — Bummer *2024-03-12, version 2.8.4* I have enough coins to cash out but it sends me an email to go to the cash out page and it does nothing ## Frequently asked questions about Bitcoin Soduku ### What is Bitcoin Sudoku?
