What is Crash?

Crash is an online multiplayer blockchain guessing game that made as an increasing curve that may crash at any time.

How to play it?

Before the game starts you have 6 seconds to place your bet. After the game starts the multiplier will get higher and higher starting from 1.00x.

You can click on "Cash Out" button at any time to lock in the current multiplier, and your payoff will be your bets times the current multiplier.

The longer you stay in the game the higher payoff you will get. Please be noted, however that curve may crash at any moment. If you fail to cash out before the crash, you will lose your bet.

Are you going to cash out at 1.01x, or are you going to stay until 100x, 1000x, 10000x...? It's all your call - which has tto be made in a split of a second!


What Is Crash War?

Crash War is built on top of the popular Crash Game. Crash War allows the player to wager on the outcome of the game, RED or Green.
Crash War probability is simple.
The chances of hitting a Red is 50.5%. The chances of hitting a Green is 49.5%. The house edge is 1%.
Red pays x1.96 the wager. Green pays x2 the wager.

How To Play
Before the game starts, players have 6 seconds to place their bet, players selects RED or GREEN.
After the betting period, CRASH will start running until Bang, signifying game over.Red pays x1.96 and Green pays x2.
Players can play Crash and Crash War at the same time, or they may play the games individually.


What is the bankroll?

The bankroll is the pool of money that the bankroller uses to pay out winners of the game.
The max profit that players can win from a round of the game is determined by the size of the bankroll. The larger the bankroll, the more players can win.
Each player can only win 0.75 % of the bankroll per round
All players can only win 1.125% of the funds per round
Players can bet on the bankroll (i.e. become bankrollers), and their bet is added to the bankroll such that they win when the house wins and they lose when the house loses.

How does the pool of funds operate?

The bankroll implements a shareholding system that allows everyone to participate and obtain the corresponding shares.
The house edge is 1%. 99% of each bet will go to the bankroll, and the remaining 1% will be reserved for platform operating costs.
Payouts made to the winning players will be deducted from the bankroll.

How does leverage investment work?

We'll add the selected multiplier to your initial investment ( minus dilution fee ). If the Bankroll goes down and your initial investment goes to 0, you're get liquidated and you lost your investment.
Hint: You can also use this feature as an Off-Site investment.
Let's make an example:
Let's say have 1 Bitcoin. You could deposit them to your Account and invest them all. You would now be entrusting your whole 1BTC to Bc.game, with the associated risks. Alternatively, you could deposit just 0.1 BTC of them, invest them, and then tell the site "I have 0.9 more BTC that I want to invest". You keep those coins safe in your own wallet with your own private key, but they are counted as part of the Game bankroll. Your share of the bankroll and your share of the site's profits and losses is the same as if you had invested your whole 1BTC. If the site should have a run of bad luck such that your 0.1 BTC goes to 0, You'll get liquidated and your leverage will be set to 0. In that way, you can never get into debt with the site but you can deposit again and keep your share of the bankroll.

What is the bankroller dilution fee?

Every time you bet on the house, 2 % of your bet is paid out to the other bankrollers according to their stake in the bankroll.
Put another way, every time somebody else bets on the house, you are awarded a portion of their 2 % dilution fee.
For example, if you bet 1 ETH on the house, then 2 % (0.02 ETH) of your house bet is spread out among the other bankrollers, and the remaining 0.98 ETH is added to your stake.
To capitalize on the dilution fee system, you will want to bet as much as you can on the house as early as possible. As you maximize your stake, you maximize your claim on future dilution fees.
This is our way of rewarding long-time bankrollers. It's never too late to become one!


Is The Game Fair? Found unfair,reward 100 ETH

We are fair and impartial prediction and guessing platform. Our goal is to eliminate all unfair factors and make players feel comfortable and have fun.
We have generated a total of 10 million hashes (the generation chain is verifiable), and each hash corresponds to a curve crash multiplier.
We release these 10 million numbers in reverse order, each corresponding to one turn of the game (i.e. we have 10 million turns in total).
In other words, the crash number of each turn already exists and is not calculated after the game starts. Players can therefore place their bet without concern.

Will The Game Be Manipulated By The Platform? Github | Verify

The integrity check value is key to verifying whether there is any official manipulation; The test algorithm is provided as follows.
Example: 6b5124897c3c48d0e46cc9249f08c7e560792459f1bad1171224643b5d2be231
Take a random value in the 2^52 range, namely 16^13, i.e. a 13-bit hexadecimal number (because the hash value is hexadecimal, 2^52 === 16^13)6b5124897c3c4 (6b5124897c3c4 equals 1887939992208324 in the decimal system).
Distribute the random value to 0~1, by dividing it by the maximum value of 13 fs, namely 6b5124897c3c4/fffffffffffff. Given the discrete random nature of the hash value, we then can think that any hash value can be transformed into a random number of 0~1 (fffffffffffff is equal to 45035996270496 in the decimal system) 1887939992208324/4503599627370496 = 0.419206889692064.
Make the house edge 1%. Further to calculate 99/(1-X), where X is the random value calculated at Step 2. When X is 0, the result is 99; when X is 1, the result is positive infinite; when X is 0.01, the result is 100; when X is less than 0.01, the result is less than 100.
Conclusion: The overall random number distribution is 99 to positive infinite; and when the random number distribution is 0~0.01, the result is less than 100.
99/(1-0.419206889692064) = 170.45656748150867
All values less than 100 will be set to 100. In other words, there is a probability of 1% that 100 will appear. Round off the number and divide it by 100 to get the final result.
170/100 = 1.70

Conclusion: The hash value used in the game is inverse ordered. Therefore, with the SHA256 algorithm, a previous hash used in the game can be calculated from its subsequent hash. Since there is one-to-one correspondence between the key and the value of hash, we can draw the conclusion that if a hash can be used to calculate the hash that precedes it, then this hash should have been already generated when the preceding prize is announced. Similarly, the entire hash chain is generated at the very beginning and cannot be changed once generated. Otherwise, it cannot pass verification by SHA256, and as far as the payout is concerned, this is nothing more than a probability game in which crash is a given. The official organizer cannot manipulate any game set. Therefore, CRASH is more transparent than other gambling methods. This is the cornerstone on which our game is built.

Simple calculation:
When the 13-bit hash value is 8000000000000 = 1.98, 0xb000000000 = 3.168, 0xc000000000 = 3.96, that is, the first digit is greater than 8((16-8)/16≈0.5), the result is approximately 2x; when the first digit is greater than b((16-11)/16≈0.3), the result is approximately 3x; and when the first digit is greater than c((16-12)/16≈0.25), the result is approximately 4x, and the same rule applies to the rest.
When the 13-bit hash value is f000000000000 = 15.84, ff00000000000 = 253.44, fff000000

Auto Cash Out

Why Is There Internet Lag?

Since CRASH is a real-time online game (a game in which customers interact with it via the Internet), there is a delay between the time you click on the “Cash Out” button and the time when the server receives your cash out instruction.
The farther away you are from the server and the worse your Internet connection is, the longer it will take for your message to reach the game server.
In a perfect environment, your message can travel to the server at the speed of light, but it still takes 134 milliseconds to travel around the world.

What's the Use of Automatic Cash Out?

The best way to avoid damages caused by Internet lag is to use the automatic cash out function. Since your automatic cash out is sent to the server at the same time when you place your bet, the server can execute your cash out instruction precisely and regardless of the lag.

For example, if your connection is bad and you want to cash out at 2x, then we recommend that you set automatic cash out to 2x rather than cash out manually at 2x, because after you click on “Cash Out”, the curve may crash before your message reaches the server.

What Should You Do If the Game Is Accidentally Disconnected?

When we notice that you are disconnected from an active game, we will try to cash out for you.
However, we strongly recommend that you use the automatic cash out function to deal with this issue.
Since your automatic cash out multiplier has been sent to the server, you can still cash out normally even if you are completely disconnected. This is the most reliable way to avoid damages caused by accidental disconnection.
