Easy Bitcoin game. Forum-based. No randomness here, the winning number is calculated with the formula. Bets (in BTC) closest to the number generated by the formula in both directions win. Quantity of winners depends on quantity of bets.

The code will execute every Monday 12AM - 12:10AM (00:00 - 00:10) UTC. Payouts are made at the same moment.

You can play it as a game of luck or manipulate the winning number using the formula and making more bets (calculator is in Excel file, link below).

Make your bets to this address: 35WGYwD9jtrqXf1z7eQsUwvBUK1ZfJSQhP

Example 1
Bet (BTC)
0.00032232
0.00231414
0.00714341
0.00821414
0.01241143 - winner gets 0.02860604
Winning number: 5.28761133

Example 2

https://i.postimg.cc/rFppGf8F/frm.gif
S – sum of all bets
Q – quantity of bets
A – average bet (S/Q)

Winning number calculator is on GitHub, link below.
See results and competitors on the blockchain explorer.

Winners get their bet back + 90% of bets that lost the game. House gets remaining 10%.
If there was only 1 bet in a day - 100% refund.
2-10 bets - 1 winner (90%).
11-30 bets - 3 winners (50-30-10%).
31-50 bets - 5 winners (30-22-16-12-10%).
50+ bets - 10 winners (25-19-14-10-7-5-4-3-2-1%).

Source + winning number calculator: https://github.com/dev-BBB/BBB

1 bet (1 game unit) - 1 transaction with 6 confirmations. If any transaction got 6 confirmations after the game time, it will be taken into account on the next week. Different transactions don't sum up into 1 bet. Also there will be no refunds except the situation with only 1 bet.

The formula might encourage players to bet bigger amounts, however you can manipulate the winning number by making more bets with small or big amounts, so everyone has a chance.

The BTC address where the reward will be send - the 1st one in the winner's transaction.

Post here your winnings and good luck everyone!

The game awaits first players! Please participate and reply what you think about this game!

Wasn't thinking about scamming anybody, just decided to start a little game here. Besides how many you know who speak C++ that ever became villains? Wink
