2. 🎲 Simple "Rand-Between" Contract

• ⚠️ Use with Caution; Since the Ethereum blockchain and its derivatives are considered deterministic systems, this type of implementation lacks reliable randomness, in other words, we don't have a VRF (Verifiable Random Function). Therefore, it's better not to use this kind of implementation if you have contracts that handle significant amounts of money.

3. 🎰 Commit/Reveal Schema for "Rand-Between"

• Relative to a simple random approach, this method is better as it is both cost-effective and highly reliable. If you do not want to use tools like ChainlinkVRF, this method will help you.

5. 💞 Lovers Q&A

• Ask a question and simultaneously send the question and its answer in secret and hashed form to the contract. Now it's your partner's turn to respond to your question. This contract has the capability for you to pose any number of questions within it, and your partner can respond to those questions. Whenever a question concludes (whether your partner answered it correctly or incorrectly), you can ask the next question.
