Fishing and Arcade Games
Fishing games are not just fun — skill and strategy also play a role. Choosing the right cannon power and target is the key.
How Fishing Games Work
Various fish swim across the screen. You shoot them using a cannon to catch fish. Each shot costs a set amount (bet value). When a fish is caught, you receive a reward based on its multiplier. Increasing the cannon level raises its power, but also increases the cost.
Boss Fish and Special Fish
Small fish are easy to catch but offer smaller rewards. Large fish and boss fish require more shots to catch, but the winnings are much greater. Catching special boss fish can earn jackpot rewards.
Types of Arcade Games
Beyond fishing, the arcade category also includes hunting games (West Hunter Bingo), dinosaur games (Dinosaur Tycoon) and special event games. Each game has its own theme and reward structure.
Cost Control Tips
Always keep the cost per shot in mind. Start with lower-level cannons at the beginning and increase the cannon level once you understand the rhythm of the game. Plan to play within a fixed budget.

RTP and House Edge Explained
RTP, or Return to Player, is a theoretical measure of what percentage of total bets placed on a game over a long period is returned to players. For example, if a slot's RTP is 96%, it means on average ৳96 comes back for every ৳100 wagered — however, this is not a guaranteed outcome for every session; it is the mathematical average across millions of rounds.
The typical RTP range varies by game type. Slot games generally have an RTP of 92%–98%, blackjack can approach around 99% with correct strategy, and roulette is usually 94%–97%. These figures are a general guideline — individual experiences may differ.
House Edge is the flip side of RTP — it is the casino's average advantage. Subtract RTP from 100% and you get the House Edge. If a game's RTP is 96%, the House Edge is 4%. A higher RTP is generally more favorable for the player.
Knowing the RTP and House Edge before you play allows you to choose games more consciously. Keep in mind that RTP is a long-term statistic — short-term results can differ from it significantly. Also consider volatility.
Bankroll Management Guide
- Set a fixed budget: Before you play, decide the maximum amount you are willing to spend. This amount should only be what you can afford to lose without it affecting your daily life. Never play with borrowed money or household funds.
- Divide your budget by session: Split your total bankroll across multiple sessions. Try not to spend more than 20% of your total bankroll in a single session. This reduces the risk of losing everything in one bad session.
- The 1–5% per bet rule: Do not place more than 1% to 5% of that session's bankroll on any single bet. Following this rule makes it easier to avoid sudden large losses and gives you more time at the table.
- Take a break even after a win: It is natural to feel the urge to bet more after a big win, but this is risky. Set aside a portion of your winnings, withdraw the rest, and if you want to keep playing, start fresh from a new session's budget.
- Keep a record of your play: Track how much you deposited, won, or lost in each session. This information will help you understand your own playing patterns and make more informed decisions.

Betting Terminology
A simple explanation of common betting and casino terms for new players.
RTP (Return to Player)
The theoretical rate at which a game returns a percentage of total bets to players over a long period of time. A higher RTP is more favorable for the player.
House Edge
The casino's mathematical advantage — subtract RTP from 100% to get the House Edge. A lower House Edge is better for the player.
Wagering Requirement
Determines how many times the bonus amount must be wagered. Example: 25x wagering means you must place ৳25,000 in bets on a ৳1,000 bonus.
Odds
A numerical expression of the probability of a specific outcome. Higher odds mean a higher reward but lower probability. Correctly evaluating odds is central to a betting strategy.
Bankroll
The total amount of money set aside for playing. Sound bankroll management helps you play longer and keep risk under control.
Volatility
The level of risk in a game. High volatility means big wins come less frequently. Low volatility means smaller wins come more often.
Free Spin
An opportunity to spin for free in a slot game. Often given as a bonus. Free spins may carry their own wagering conditions.
Live Bet
Placing a bet in real time while a match is in progress. Odds change continuously and quick decisions are required based on how the game is unfolding.
Cashout
The ability to cash out a portion of your bet before the event is over. Used to reduce risk or lock in a guaranteed profit.
Parlay / Accumulator
Combining multiple bets into one larger bet. If all selections are correct, the reward is much higher, but a single wrong pick means losing everything.
Stake
The amount of money you place on a single bet is called the Stake. A higher stake means more risk and a higher potential reward.
Spread
The expected point difference between two teams. In spread betting, you win only by predicting the point difference correctly.
