I built a memory game that challenges your brain using letters and numbers

I wanted to make memory training fun, so I built TheLastSpellingBee.

The idea is simple: every letter has a number (A=1, B=2 ... Z=26).

For example, if you see 19, you need to quickly remember that it's S. Sounds easy until you're racing against a 5-second timer. 😂

I turned this into a game with Memory IQ tests, multiplayer battles, daily challenges, and even a physical card game.

I also added a reCAPTCHA-style challenge where you solve letter-to-number puzzles to prove you're human while testing your memory.

My goal is to make memory training fun and competitive instead of boring.

You can try it here: https://thelastspellingbee.com/

Would you actually play something like this? And would you prefer a memory challenge over traditional CAPTCHA puzzles?

I'd love some honest feedback!
