Win at Online Casino and Jackpot Slots on 3666 bet
A platform trusted by thousands of players in Bangladesh — slots, fishing games, live casino and cricket betting all in one place. Withdraw in minutes via bKash, Nagad and other familiar payment methods.
Fishing Games — Aim at Targets, Collect Rewards
In fishing games you control a cannon — choose the cannon level to set your bet. Shoot at the fish and sea creatures swimming across the screen; small fish are easier to catch but pay less, while landing a large boss creature pays out big. Play solo or join other players at a shared table — the excitement builds with every shot.
Mega Fishing
Fish of all sizes fill the large map — in boss rounds multiple big targets appear on screen at once.
All-star Fishing
Catching a special starfish increases the multiplier — other players can be hunting at the same table at the same time.
Fishing God
When a special deity fish appears on screen everyone focuses at once — catching it guarantees a big reward.
5 Dragons Fishing
Five dragon-level cannons — the higher the level, the bigger the targets and the greater the rewards.

Live Casino Game CollectionThe Jackpot Games
3666 bet has several types of jackpot games — each with its own rules for how the prize builds up. There is no guarantee of winning, but every bet contributes to the jackpot fund.
A jackpot chance on every spin
Progressive Slot Jackpot
A portion of every bet is added to a central pool. When a specific symbol combination or bonus round triggers the pool, one player takes the entire prize.
Fishing Game Jackpot
Shooting and catching a mega-boss fish or a special event creature triggers a jackpot pool with a large multiplier.
Live Casino Side-Bet Jackpot
Placing an extra side-bet at a baccarat or roulette table gives you access to a separate jackpot pool.
Fixed Jackpot Slots
The pool does not grow, but a set amount is guaranteed — this format appears in games such as Gates of Olympus (Pragmatic Play) and Fortune Tiger (PG Soft).
