The game based from the images looks bearable at this point but my main concern about betting games like this is they do need to have a license first before they legally operate in a betting game. So my question is are you already licensed and if you are what is the jurisdiction that grant license for you? Since I didn't see any mention about the legality of your game I am presuming that you are still unlicensed for it so I think you should also manage some time in getting it before you even try to make your website officially running.
Thanks for reply. I would not say, "Bearable", There is some more progress than in the pictures.
And about the license, you are right, I'm not an legal expert, but I had in mind no license, not sure if it's needed since, it's not gambling nor "real betting", it's not like sport where you bet for a team, or you gamble against the casino, not sure if this applies here, here in Spain cryptocurrency is not considered as a currency. Maybe there could be a legal void to workaround? Like using different terms, or buying something in the website that allows you to play, something like coins that have 1:1 value tied to bitcoin, not sure.
I would stop you right there. Any game that involves players putting some money on it to win is considered as gambling. No matter what you call it may it be as a wager, bet, or prize money it still counts as gambling and you need a gambling license to legally operate your Checkers game. Now I would understand if players doing side bets externally from your website but if bets/wagers are done internally which involves the use of your website then it counts as gambling. You may also think that Checkers might not be a normal game for gambling that's why you think there is a exemption but the thing about gambling is it involves money and that's it.
