🟥⬛ Roulette.cool - Your lucky spin, anytime. | No KYC | House Edge 1,35%

[Roulette.cool]

At the turn of the year, we added a new game: Coinflip. The game is similar to a classic heads or tails game with a 50% chance of winning, whereby a correct bet pays out the stake x2.

This means that there are now two games available on roulette.cool:
The roulette table with a house edge of ≈ 1.35% and the coin flip game with a house edge of 0%.

Initial announcement:

We are very pleasured to announce the official launch of our project roulette.cool today.

At roulette.cool, you can play roulette in its purest form with transparent and verifiable random number generation (Provably Fair Technology).

When creating roulette.cool, we deliberately focused on making the game as minimalistic and clear as possible – the design follows the function. Roulette in its purest and most honest form!

We have also kept the path to the game, the login system, and the function for depositing and withdrawing funds as simple and secure as possible.

Our motivation: to design the game and make it playable in the way we ourselves prefer. And to make the game as easy to access as possible while ensuring maximum security.

Although perfection, continuity, and simplicity are supposed to be the core values of roulette.cool,
we are of course open to meaningful improvements. We are always open to suggestions from users on how to improve roulette.cool – feel free to post them here in this thread on bitcointalk.org.

Our goal is and remains: roulette in its purest and most honest form.


🢂 New players can sign up anytime and instantly receive play money to explore the game or simply enjoy playing in play money mode.


You can reach our support team at our support email address support [at] roulette.cool.

🢂 Important Notes:

[1] The house edge of our roulette table is effectively 1.35%.

We achieved this by introducing a new rule inspired by the historic La Partage rule in French Roulette:

If the ball lands on 0, the player receives 50% of their bet back — regardless of which field they placed their bet on.
For bets placed on 0, this new La Partage rule applies when the number 36 is hit.

So: All bets when the ball lands on 0: 50% refund of the stake.
For all bets on 0: 50% refund of the stake if the ball lands on 36.

Of course, this rule is completely customizable: For example, you can bet 10 Satoshi on 0 and 10 Satoshi on 36 in one round.
The ball lands on 0. Result: 360 winnings on 0 and 5 refund on 36 = 365 winnings on a 20 Satoshi bet on two different single numbers.

With this change, we have managed to mathematically reduce the casino's house edge to 1.35%!

Important: For bets with odd stakes such as 11, 13, 153 and so on, the refund is rounded down:
So for a stake of 11, the refund is 5.
For a stake of 13, the refund is 6.
For a stake of 153, the refund is 76.
This means that for bets with small, odd stakes, the house edge is not actually 1.35% due to rounding.
Only with slightly higher odd bets does the house edge approach 1.35%.
Example: Bet 507. House edge: 1.3540167.
However, for bets with equal stakes such as 6, 10, 14, etc., the house edge is 1.35% from the beginning.
This is a compromise we had to make with the new rule to avoid half satoshis, which do not exist.

Just as a reminder:
The house edge in standard European Roulette (single zero) is 2.7%, and 5.26% in American Roulette (double zero).

This house edge exists because, although there are 37 possible numbers on the wheel (38 with double zero), the casino only pays out 36 times the bet on a straight-up number (18 times on split bets, and so on).
That means that even though the chance of winning on a single number bet is 1 in 37 (or 1 in 38 in American Roulette), a win only returns 36 times the bet.

Our change — to our knowledge unique worldwide — effectively halves the risk posed by the 0, the 37th number, for the player.
As a result, the house edge for all bets shifts to 1.35%.

[2] The house edge of the Coinflip Game is 0%.

You can bet on ₿ or 1, which corresponds to heads or tails on a classic coin.
A correct bet is paid out at 2 times the stake. If the bet is incorrect, the stake is lost. This means that the house edge is 0%.

🢂 Frequently asked Questions:

[1] How exactly is the random number generated?

The random number for each game round is generated from three components:

The server seed, which is generated on the server side by roulette.cool.

The nonce, which starts at 1 and increases by 1 with each round played,
making it independent.

The client seed, which is generated in the user's browser or, alternatively,
can also be set manually by the user.

You can read in detail here how exactly the random number is then drawn from these components,
and how you can verify why this draw was unpredictable for all parties (users and bank) thanks to technical parameters: roulette.cool/provablyfair

[2] How do deposits work?

You can make deposots via https://roulette.cool/deposit, which you can also access via the menu.

To make a deposit, you must generate a deposit address by clicking on the corresponding button.

All amounts paid into the generated address will be credited to your account.

This address is assigned to your user account for 72 hours. This address will then remain assigned to your user account for a further 7 days. During this time, however, you should no longer send any new deposits to this address, but instead generate a new one. Please take this into consideration for your Bitcoin deposit transaction to avoid errors.

[3]How do payouts work?

You can make payouts via https://roulette.cool/payout, which you can also access via the menu.
Simply enter the withdrawal amount and the recipient address. Please note the minimum payout amount of 30,000 satoshi. Withdrawals are processed within 24 hours.

Just checked your site out and it's very barebones even if it's just one game. It's like you designed the site within an hour or something which would scare away gamblers easily. The ANN presentation itself needs improvement too.

What exactly is the house edge here? Why would anyone want to play here when this game is offered on literally every crypto gambling site out there with varying house edge percentages?

[Jawhead999]

Welcome to the forum roulette.cool

Clean, simple, provably fair, and no KYC.

Actually it's good, but I'm not sure how your casino can compete against other?

Not saying you're bad, I'm just thinking what would be a reason people would shift to play from roulette on big casino to this one, people might give a try, for long term I doubt.

What exactly is the house edge here? Why would anyone want to play here when this game is offered on literally every crypto gambling site out there with varying house edge percentages?

Welp, good point.

[Cointxz]

What exactly is the house edge here? Why would anyone want to play here when this game is offered on literally every crypto gambling site out there with varying house edge percentages?

There’s less info about the house edge but considering this casino European Roulette type while the computation of result is a straight RNG on 0 to 36 number result then the house edge is approximately the standard HE of this game which is 2.7%.

The website is designed poorly so the only advantage on playing to this casino is the PF system on each bet.

I will not risk my bankroll just for the sake of simple PF system while there’s a live game roulette already that we can verify the game result using our naked eye.

Hello Haunebu, thank you for your feedback.

Well, the reason could be that someone just wants to play a few numbers quickly without all the whistles and hurdles that other sites require of players. With us, you can simply log in quickly and start playing.

The house edge is 2.7%, as is usual for a (European) roulette table. There are 37 numbers (0, 1-36). If a number is hit, the bet is multiplied by 36. The same applies to all other bets, e.g. if the chip is placed on 4 numbers, the bet is multiplied by 36/4= 9 if a number is hit.
All bets possible at a real roulette table are available and have the corresponding payout factors.

The house edge in European roulette is always a fixed value of 2.7% (1/37), which corresponds to an RTP of 36/37 = 97.3%.

So minimalist in design, lol... not a single piece of informations on your site, not even the terms and conditions, I mean, it's literally a desert out there. Man, what were you thinking when you created this site? It seems you were in a hurry. I also saw that the minimum payout amount is 30000 satoshi, but what about the deposit amount? I'll be honest,, I don't find the site any attractive and wonder how many would actually try it.

Lastly welcome to BTT forum!

Welp, good point.

We are actually focusing on establishing ourselves as a safe bank for roulette bets in the long term.

We don't want to compete with the big bling-bling casinos. We simply want to offer the opportunity to place bets safely at the roulette table.

I think the existence of dice game sites in particular shows that there is demand for such offers.

So it's a single 0 good, at least it's better that the 00 double.

Hopefully you can true with your words as I remember one platform that focuses on roulette, unfortunately, after a couple of months they started to sell their site. In any case, you really need to have a good ANN thread so that gamblers here are going to be attracted and maybe test your site.

We will take this into account and add more detailed explanations of the game function in the future.

The lower limit on the payout amount is intended to make the payout function economically viable. Smaller payout amounts would exceed economic viability due to the fees charged by the Bitcoin network.

Of course, this is a point that can only be confirmed over time. Our goal is to be a secure, long-term bank for online roulette betting.

We will prove that.

I like the minimal design. There's absolutely no need for all the shiny buttons etc when all you want to do is play some quick roulette. You have a solid USP there.

Thank you, thats exactly how its meant to be - we will build on that.

This is the problem right here. Why would anyone want to play here with the standard house edge when they could do the same in big sites while taking advantage of their VIP systems in the short-term and long-term?

I specifically asked this question because I was wondering if your team offered reduced house edge roulette, but that clearly isn't the case. Good luck!

Now I understand. Jackpots, bonuses, VIP systems mean that the actual house edge is effectively lower.

In fact, we could work well with a significantly lower house edge.

We will definitely look into that. I already have an idea of how to implement this to reduce the house edge. Update to follow.

For me maybe others gamblers want to explore new platform, like this one and see what they can offer.

Yes, it's a standard house edge, I don't think that they can go and above or below that in roulette. Definitely, there are rake back and other promotions from other site specially if you are a VIP member and has a lot of perks.

But then again, to break that boredom or just trying to experience a different site, maybe there could be gamblers that loves roulette that will test new casino.

Welcome to the forum, OP. Like what some of my companions here are saying, why did you launch a casino with only one game on your website?

I'm asking this because I'm sure you know the competition in the crypto gambling business is intense.  Their competitors have many games
available, divided into several categories, not to mention the bonus strategies they offer to their players.

I saw many roulette games that has simple design yet still appealing to play. Simple doesn’t mean it should be crappy looks since we want to be entertained when gambling not just waiting for win or lose.

Visual is always the top priority on gambling unless your game is being use strictly for wagering purposes only like when you offer bonus or tournaments that requires player to wager quickly.

Anyway it’s your choice. There’s no need to adjust your design if you think that’s your goal. Have a great journey in the forum.

Welcome to bitcointalk, roulette.cool!
I took a quick look at your website and checked how your provably fair system works and it looks good. However, when I tried to change the client seed, I was able to enter a new one, but there was no option to submit it so that it gets saved. As soon as I refresh the page, it shows the old client seed again instead of the one I set, which means the change hasn’t been applied!

I find it interesting that you describe our website as poorly designed. Actually, that was precisely the goal: to make the service as simple as possible.

Don’t take it personally, but you can improve the design to keep it simple but also attractive in the same time. Whith the current design, players can get bored too quickly just after few spins and leave.
