Types of Slot Games
45db offers various types of slot games — each with its own fun and features.
Classic Slots
3 reels and usually 1–5 paylines. Simple gameplay with fruit, bar, and seven symbols — older classics from NetEnt and Microgaming fall into this type.
Video Slots
5 reels, impressive graphics, free spins, and bonus rounds. PG Soft's Fortune Tiger and Pragmatic Play's Gates of Olympus fall into this category.
Jackpot Slots
A portion of each bet accumulates to build a massive jackpot. Microgaming is a pioneer in this type of game.
Megaways Slots
The reel height changes on every spin, creating thousands of payways. This mechanism, invented by Big Time Gaming, is used by many providers.
Cascading Reels
When winning symbols disappear, new symbols fall from above — multiple wins are possible on a single spin. Pragmatic Play's Sweet Bonanza is a prime example.
Cluster Pays
Instead of paylines, you win when 5 or more of the same symbols form a cluster side by side. PG Soft's Mahjong Ways series works this way.
Betting Exchange — How does it work?
In a regular sportsbook, you bet against the bookmaker. In an exchange, you bet against other players — there is no bookie. That means you can take either side: backing an outcome (Back) or betting against it (Lay).
| Back Bet | Lay Bet |
|---|---|
| Bet that the event will happen | Bet that the event will not happen |
| Bet on a team to win | Bet on a team to lose |
| Like a regular bookmaker | You play the role of the bookmaker |
Bangladesh Tigers to win — place a Back bet of ৳500 at odds of 2.0 and you receive ৳1,000 if they win. On a Lay bet, you hold another player's ৳500 and you win if the team loses.
The odds assigned on an exchange are driven by market demand — they are set directly by other players. The platform typically takes a small commission on each win.
Fast Withdrawals — No Waiting
Getting your winnings at 45db is now easier than ever. Via bKash, Nagad, Rocket, or bank transfer, the money reaches your wallet within a maximum of 2 hours.
- Instant processing for bKash and Nagad — usually within 15 minutes.

Fishing & Arcade Games
From fishing to thrilling arcade — every game is a new experience.
🎣 How do Fish Shooting Games work?
In a fish shooting game, you control a cannon and shoot the fish swimming across the screen. Each fish has a different point value — small fish are worth less, large fish and boss fish are worth more. Upgrading the cannon level increases the cost per shot but also increases its power.
Boss fish generally offer large multipliers but require many more shots to defeat — so make decisions based on your cannon level and budget. JILI's Mega Fishing, All-star Fishing, and Bombing Fishing are popular games of this type.
- Start with a small cannon
- Don't waste all your shots on boss fish
- Grouped small fish can be more profitable
- Common fish — low points, easy
- Special fish — medium multiplier
- Boss fish — high rewards, difficult
Classic Fishing
Traditional fishing — simple rules, ideal for beginners.
Bombing Fishing
Use explosives to catch more fish at once.
Royal Fishing
High-stakes fishing — high bets, high rewards.
