Fishing & Arcade Games
Beyond slots and casino, 77b2b also offers fun fish-shooting and arcade games.
In fishing games, you have a cannon to shoot fish underwater. Each shot has a fixed cost — the more powerful the cannon, the higher the cost, but also the greater the chance of catching big fish. Small fish appear more often but pay less; boss fish (large boss characters) are harder to catch but carry much higher multipliers.
🎯 Choose Your Cannon Level
If you're a new player, start at the lowest level. As you gain experience, gradually increase the power.
🐟 Fish Multipliers
Each fish has its own point multiplier. Catching a boss fish can earn you a big reward in one shot.
💰 Control Your Spending
Set a budget keeping the cost per shot in mind. Avoid firing too many shots at once.

RTP and House Edge Explained
Know before you play — this information will help you make informed decisions.
What is RTP (Return to Player)?
RTP refers to the percentage of total bets a game returns to players over the long term. Example: a 96% RTP means an average of ৳96 is returned for every ৳100 wagered — but this is an average across millions of rounds; each round's outcome is separate and random.
Typical RTP ranges for different games
Slot games generally have an RTP of 92–98%, varying by title. Blackjack can reach close to 99% RTP with correct strategy. Roulette is around 97.3% for the European variant and lower for the American variant. To verify the RTP of a specific game, check the game developer's page.
What is House Edge?
House edge is the casino's mathematical advantage — essentially what remains when RTP is subtracted from 100%. Example: a 96% RTP means a 4% house edge. This margin ensures the game developer's profit over the long term. However, any outcome is possible in the short term.
Why does volatility matter?
In high-volatility games, wins come less frequently but are larger in size. In low-volatility games, wins are smaller but more frequent. Choose volatility according to your budget — many sessions can end without a win when chasing big payouts in high-volatility games.

Learn the key terms commonly used in online casinos.
RTP
Return to Player — the percentage of total bets a game returns over the long term. A higher RTP is generally more favorable for the player.
House Edge
The casino's mathematical advantage — what remains when RTP is subtracted from 100%. This is the source of the casino's long-term profit.
Wager / Wagering
A requirement to place a certain amount in bets before a bonus can be withdrawn. For example: 25x wagering means you must bet 25 times the bonus amount.
Stake
The amount of money you are risking on a single bet. The stake can be adjusted each round or spin.
Odds
A numerical expression of the probability of a specific outcome. Higher odds mean lower probability — but the reward is greater if you win.
Accumulator / Parlay
Combining multiple bets together. If all outcomes are correct, you receive the total multiplied reward — both risk and reward increase.
Live Bet
Placing a bet in real time on a match or game in progress. Odds change every moment — quick decisions are required.
Cashout
Settling a bet at its current value before the match or game ends. You receive less than the full reward, but you can avoid a loss.
Bankroll
The total amount of money you have set aside for playing. Managing your bankroll as a budget is the key to playing over the long term.
Volatility
A measure of the frequency and size of wins in a game. Low volatility = frequent but small wins; high volatility = rare but large wins.
Free Spin
Free spins received as a bonus — a chance to play slot games without spending your balance. Wagering requirements may also apply to free spin winnings.
Spread
In sports betting, a wager based on the point or run difference between two teams. A run spread bet on a Bangladesh vs India match is a common example.
