First version of smart contract premiered exactly now with this topic on Polygon Network.

Game logic Polygon
Creation of contract for "doubling" revenue of two players with amount of 0.1Matic each
0x7196f59B7A17252524Ebb7C75908E452BFf1500E

First wallet sends exactly 0.1Matic to contract address 0x7196f59B7A17252524Ebb7C75908E452BFf1500E
- in this tx First wallet checks who is winner in previous stage and executes sent withdrawal 0.19Matic to winner

Second wallet sends exactly 0.1Matic to contract address 0x7196f59B7A17252524Ebb7C75908E452BFf1500E
- in this Second wallet transaction from block timestamp and 9 hashes generates Combo Number, that is written to a smart contract
   from this block gets timestamp and from it chooses 9 "random" hashes in blockchain and generates Combo Numer if it ends with one of this "even" numbers "02468" - Chosen Winner is First Wallet, previous
   if this comboNumer ends with one of this "odd" numbers "13579" - Chosen Winner is Second Wallet, this
- in this tx dev fee in amount 0.01Matic executes

You need to wait two transactions after yours to get payout, if blockchain choose you as a winner...


Game logic BSC Network
Creation of contract for "doubling" revenue of two players with amount of 0.01BNB each
0x8af75e8DE6c766a934871c6ec0733d262fE08089

First wallet sends exactly 0.01BNB to contract address 0x8af75e8DE6c766a934871c6ec0733d262fE08089
- in this tx First wallet checks who is winner in previous stage and executes sent withdrawal 0.19Matic to winner

Second wallet sends exactly 0.01BNB to contract address 0x8af75e8DE6c766a934871c6ec0733d262fE08089
- in this tx Second wallet transaction block timestamp writen to a smart contract
   from this block gets timestamp and from it chooses 9 "random" hashes in blockchain and generates Combo Numer if it ends with one of this "even" numbers "02468" - Chosen Winner is First Wallet, previous
   if this comboNumer ends with one of this "odd" numbers "13579" - Chosen Winner is Second Wallet, this
- in this tx dev fee in amount 0.001BNB executes

First two pairs of transactions will looks like these, and so on:

---

First stage
Seed. First version of Smart Contract published on Polygon Network with 0.1Matic entrance

Second stage
Growing. If interest to this topic will be enough, we publish contract source code on all Networks and on GitHub and will create other Smart Contracts with higher amounts and on other networks (BSC, Fantom, Optimistic, Linea, Ethereum)

Third stage
Stress test. On this stage we can pay for audit services from Dev Fees.

Fourth stage
Next, updated version of contract developed, created UI (User Interface for web and possible to mobile devices)

Will be appreciated for collaboration, advice's, help in promotion, etc.

Hello. Happy for your reply and interest.
This scheme I can't recognize this as ponzi, because ponzi is endless hierarchy, when people, that comes later will always lose, if not invite someone.
This scheme and result depends on hash of transaction, that ends, when only two persons bet.
Also ponzi scheme guarantees profit when next user comes. In this scheme on of two users will lose.


2nd Winner will receive funds in 5th transaction.

Simple graph in this post

You need to wait two transactions after yours to get payout, if blockchain choose you as a winner.

In short words in this scheme can play two players never inviting someone else. One player is also possible (in this case dev fee only losed).

The contract source code will 100% be published! The only thing I propose is to make a little stress test before. We can decide with community when exactly its better to do.

0.1Matic to test it - is good enough, I think.
Every second transaction contract should be empty (its NOT accumulates Matic), because its withdraws all balance to winner between two users with fee.

For now I propose to see results on blockchain.

No website to put landing page for an easy understanding to your work? This is still on testing phase so it’s better if you will still put this topic on project and development since you will still need for testers to try your game instead of releasing it here half baked because you will encounter difficulty here to find user who will send tokens on your smart contract address.

Since this is a smart contract based games. Are you planning to audit your source code to a trusted smart contract auditor?

You need to create a video for this, I have a hard time understanding the concept but a graph or better a video on how this thing works will give us a full understanding of the full concept, this is new and interesting I'm not a fan of contract based gambling but I welcome new ideas that deal with contract based gambling, I hope you can come out with a video or better hire a designer to create a flow chart to fully illustrate the whole idea.

The video little bit boring, but from myself and quick posted. Hope next videos will become more interactive.

Its possible, that you're right. Let's see.

If this CoinFlip is not available on bitcoin blockchain than I am not really interested and I cant test it if I dont use coins you mentioned.
Smart contracts always have bigger or smaller bugs and it is possible for someone to exploit them like it happened already for many projects.
There is another thing I dont like when you mentioned to send double amount for better chances, that sounds a lot like old scams that offer to double your bitcoin.

I saw there are many other layer networks that are connected with main bitcoin blockchain, not just omni, so maybe you can research more about them.
I think they work very similar like blockchains but I am not expert or developer to explain the difference.

I don't understand and cant read smart contracts, and someone can easily create scam contracts that pay differently.
Did someone audit your smart contract?

So I can test CoinFlip with this test coins?

Contract with higher bet (0.2 Matic) added to Polygon Blockchain (0x26fC3ED19E40a91Ef7257E0ebD3f865241e555dB)
Added into a table it starter post. Future contracts with higher bets will be added into this table.

Thanks for audit companies list - will check them and send for audit, when Dev fee will be enough to pay their services.

I can clarify, that exactly thread will be platform for First stage, because all calculations and checks is inside Smart contract made, and block explorer is a transparent database for all transactions made through Contract. So own platform needed just for User Interface in our case and not for manipulations with choosing winner, that's main point, Block timestamp in seconds chose who is winner (As i hope that its fair random number, the only risk I see, that the miners can manipulate with Timestamp, but not sure that is easy). Hope its really unique idea and will be interesting for players.

Bitcoin not need website to use bitcoin as a Smart Contract not requires. Anyway in next stages it can and seems will be, if will be enough attention and interest.

Regarding test discussion: I'm not recognize it as a test, because Contract published on mainnet of Polygon. In same way we all can agree, that all Blockchain projects including Bitcoin is an our Global test... but we using it as value since 2009, until new bugs find to fix the code. Contract code - is simple, but can be not perfect, to fix disadvantages in new versions.

The thing that it has bugs can be also covered from other side with thing, that is too good (and works like a clock), and attracts enough attention to slow down blockchain like it was with some other games. That's why I planning to show source code on next stage, when attention will be enough, or community decides, that is better to publish it earlier, than later.

Fixed in new version Contracts on Polygon
0x7196f59B7A17252524Ebb7C75908E452BFf1500E with Bet 0.1 Matic
0x0a7C520273FF2b37013E844Cd133960Eb31BA52C with Bet 0.2 Matic

BSC
0x8af75e8DE6c766a934871c6ec0733d262fE08089 with Bet 0.01 BNB

Logic changed - now for choosing winner need Timestamp and 9 hashes
So to "Bad" miner needed to control not just timestamp but hashes of 9 blocks, while no bets made, to chose as a winner himself.
