Jackpot Games — A Chance to Win Big
by77 offers several types of jackpot games. The way each jackpot grows differs — the main types are explained below.
Progressive Jackpot Slots
A small portion of each player's wager is added to the jackpot pool. The more people play, the larger the pool grows. Landing a specific symbol combination gives you a chance to win the entire pool.
Fixed Jackpot Slots
In this type of game the jackpot amount is set in advance and does not change. The jackpot can be won by triggering a special bonus round or hitting the top symbol combination.
Live Casino Side-Bet Jackpot
While playing live Baccarat or Roulette, placing a small side bet alongside your main wager gives you a chance at the jackpot. A bonus jackpot is awarded when a specific card or number sequence appears.
Crash Game Multiplier
In crash games including Aviator, the higher the multiplier climbs, the greater the potential winnings. If you cash out before the crash, your wager is multiplied by that multiplier.
by77 — From Account Registration to First Withdrawal
The full process is explained step by step below for new players — from opening an account through to making your first withdrawal.

Fishing & Arcade Games
Fishing games including JILI's Mega Fishing, All-star Fishing, and Dragon Fortune are very popular in Bangladesh. In these games you shoot at fish on screen using a cannon — each shot costs a set amount.
🐟 Cannon Level & Cost
Increasing the cannon's power raises the cost per shot but also improves your chances of hitting bigger fish. Using a lower-power cannon for smaller fish keeps costs down.
💰 Fish Multipliers
Smaller fish carry lower multipliers, while boss fish and special creatures carry higher multipliers. Boss fish require more shots to defeat but the rewards are much greater.
👾 Special Arcade Mode
In Storm mode or Electric mode, special weapons can be used to catch multiple fish at once. This is exciting but comes at a higher cost.
📊 Cost Management
Set a fixed budget for each session before you play. Start at lower-stake levels and move toward boss fish gradually — this reduces the risk of your balance running out quickly.
RTP and House Edge Explained
RTP (Return to Player) is the theoretical average percentage of total bets that a game returns to players over the long term. For example, a 96% RTP means that for every ৳100 wagered, an average of ৳96 may be returned — but this is a statistical average, not a guarantee.
The RTP range varies across different game types. Slot games typically fall between 92%–98% RTP. Skill-based games like Blackjack can approach nearly 99% RTP when the correct strategy is followed. Roulette generally shows 94%–97% RTP, with differences depending on the variant.
House edge is the flip side of RTP — the casino's long-term mathematical advantage. A 96% RTP means a house edge of 4%. This means the casino retains an average of 4% of total bets. The house edge is never zero — it exists in every legitimate casino game.
Understanding RTP and volatility before you play is important. High-volatility games win less frequently but pay more when they do; low-volatility games may deliver smaller rewards more consistently. Choosing a game that suits your budget and playing style is the sensible approach.
Betting Exchange
A betting exchange is a platform where players place bets against each other — not against a casino or bookmaker. There are two types of bets: Back bets (betting that an outcome will happen) and Lay bets (betting that an outcome will not happen).
Example: You think Bangladesh will win. You place a Back bet of ৳1,000. Someone else places a Lay bet that Bangladesh will not win. The exchange matches these two bets. If Bangladesh wins, the Back bettor profits; if they do not, the Lay bettor wins.
Odds on an exchange are formed directly by the demand and supply of other players, not set by a bookmaker. This often means better odds than a traditional sportsbook. The platform typically takes a small commission from the winning side's profit.
| Back Bet | Lay Bet |
|---|---|
| Betting that the outcome will happen | Betting that the outcome will not happen |
| Potential profit = stake × odds | Potential liability = stake × (odds − 1) |
| Like traditional betting | Role similar to a bookmaker |
| Limited risk | Liability can be high at high odds |
Gambling Myths and Facts
Many misconceptions exist about online gaming. Knowing the facts helps you play more responsibly.
A slot is "due to pay" — if it hasn't paid for a long time, it will pay soon
FactEvery spin is completely independent. Previous results have no effect on the next spin — the RNG (Random Number Generator) determines each spin fresh.
Lost money can be recovered by placing more bets
FactThis thinking is known as "loss chasing" and it is extremely dangerous. The house edge is always present, so there is no mathematical basis for recovering losses by betting more.
Following a specific betting system will always result in profit
FactBetting systems like Martingale or Fibonacci cannot eliminate the house edge. Using these systems over a long period carries the risk of exhausting your budget.
A "hot" or "cold" streak predicts the next result
FactThis idea, known as the Gambler's Fallacy, is incorrect. In RNG-driven games every result is independent, and it is not possible to predict the next outcome from a previous streak.
Online casino games are "rigged" or manipulated
FactGames from reputable providers have their RNG tested by independent third parties. Game outcomes are completely random and are not altered to make any specific player lose.
Taking a bonus always results in a profit
FactA bonus is an opportunity, not a guaranteed profit. Read the wagering conditions before deciding to take a bonus. by77's welcome bonus has a wagering requirement of only 15 times the bonus amount — which is favorable compared to the industry average.
