REVERSE ROULETTE

Rule

Introduction:

Contribution.solutions is a technology platform offering reverse roulette, a fundraiser-assisted blockchain-based charity game, where your winnings fund your pre-selected charity or organization. We are a technology provider to enable community fundings. Not for personal player profit. We are not a casino. Provable player fairness due to on-chain randomness. In Reverse Roulette you win when you lose in traditional roulette. On average, you win often small amounts. We reward your risk taking with real payouts to your charity or organization. We do not hold player funds or charity/organizational funds as winnings are sent to the charity/organization immediately upon the spin result and trackable with the transaction ID on a blockchain explorer.

General:

● The general idea of Reverse Roulette is that you win when you lose in traditional roulette. In Reverse Roulette, when you bet on a number, say 17, and your number does not come, then you win. So with Reverse Roulette, you win on average much more frequently playing a single reverse number (or "plein") compared to traditional roulette.

● But we are not a casino. You cannot win here for personal profit. Reverse Roulette is a probability-based donation game. 100% of the wins of a player are sent immediately via blockchain to your pre-selected charity.

● Our concept: The player takes a risk and the charity wins. This is the unique concept of Reverse Roulette. If the player wins, the player enables a donation to charity without actually spending own money.

● The player is - kind of - donating risk acceptance.

Maximum:

The maximum amount or stake for one bet is 500 RON. There is no minimum amount specified.

Zero:

In case of the roulette spin resulting in zero, double zero or triple zero the house wins, not the player, just as in traditional roulette. There is no donation being made in these cases and the player's stake is lost.

The exception is the African roulette type, where a guaranteed donation of 5% is made, regardless if the player's stake is lost or not.

Examples:

Example Reverse Single:

You bet on any number other than zero or double zero.

If you bet on 17 and the 17 does not come (and neither the zero/doublezero)

THEN your charity wins the payout of 2.5% (European) or 5% (American Roulette).

Your Bet: 8.00 RON. Your Charity gets: 0.4 RON (8 x 0.05 for American Roulette).

Example Reverse Color:

You bet on red or black.

If you bet on red and red does not come (and neither the zero/doublezero)

THEN your charity wins the payout of 90% (European and American).

Your Bet: 8.00 RON. Your Charity gets: 7.2 RON (8 x 0.90).

Example Reverse Even/Odd:

You bet on even or odd.

If you bet on even and even does not come (and neither the zero/doublezero)

THEN your charity wins the payout of 90% (European and American).

Your Bet: 8.00 RON. Your Charity gets: 7.2 RON (8 x 0.90).

Example Reverse Dozen:

You bet on the 1st, 2nd or 3rd dozen.

If you bet on the 1st dozen and the 1st dozen does not come (and neither the zero/doublezero)

THEN your charity wins the payout of 45% (European and American).

Your Bet: 8.00 RON. Your Charity gets: 3.6 RON (8 x 0.45).
