BlackJack

Game Description

BlackJack is a timeless card game where players compete against the dealer to reach a hand total as close to 21 as possible without exceeding it. In Mega Casino’s version, players place a wager, receive two cards, and can choose to hit, stand, or double down. Winning hands typically pay 1:1, with a bonus payout for natural BlackJack (Ace + 10-value card).

A built-in 1.5% house edge ensures the game remains sustainable over time by slightly reducing the player’s win probability and long-term return.

Game Mechanics

• Objective: Beat the dealer’s total without going over 21.

• Payouts:

  • Standard win → 1:1

  • Natural BlackJack → 3:2

  • Dealer win or bust → Player loses wager

• House Edge Integration: A 1.5% margin is applied to maintain balance and system longevity.

Return to Player (RTP)

The Return to Player (RTP) reflects the average long-term payout to players.

$$RTP = 1 - House\ Edge = 1 - 0.015 = 0.985 = 98.5\%$$

This means that for every $1 wagered, players can expect an average return of $0.985 over time.

Practical Examples

Wager	Expected Return	House Edge	RTP
$100	$98.50	1.5%	98.5%
$50	$49.25	1.5%	98.5%

Dynamic Edge Adjustment

The 1.5% house edge automatically adjusts in response to liquidity pool conditions:

Liquidity Level	Adjusted Edge	RTP
High Liquidity (+25%)	1.2%	98.8%
Normal	1.5%	98.5%
Low Liquidity (−25%)	1.8%	98.2%

This keeps payouts fair while maintaining sustainable bankroll growth and system health.

Summary

BlackJack blends classic gameplay with on-chain transparency and liquidity-based risk management. By integrating an adjustable house edge, the game offers consistent fairness, responsible reward scaling, and a stable long-term return profile for both players and the protocol.
