- Blockchain, game page
Guess Guess Game is a blockchain-based web guessing game that delves into the themes of inertial thinking versus new memory, as well as the hidden expressions of those who have lost their sovereignty of language under the control of power and rules.

How to play?
- Click the button "Play now" or open the link: https://emair2.github.io/EM927/em-guess/GuessGuessGame/
- Answer questions to earn EM tokens.
You should know before you play:
1. You should download "Meta Mask" and connect the Mumbai Chain Testnet;
2. You will get 10 free EM Tokens;
3. You can answer each question by paying a specific amount of EM Tokens until you get it right；
4. If you get it right, you will get the corresponding EM Tokens, but you can only redeem the reward for the correct answer once per account.
5. Good luck 🤞

Hey! You know?
- There are no absolute winners in the casino, and neither is society.
- Power can seal people's mouths but not their minds.
- It's really a scam.
- It is not a game, but a hidden poem.
- Just kidding, it's just a crazy person talking seriously.
- Nice to see you.
