Years of Experience
Sin45 was born from a simple idea — to create an online gaming environment for people in Bangladesh where world-class entertainment meets their own language and preferred payment methods.
Over the years, we noticed that people in Bangladesh were running into all kinds of difficulties with foreign platforms — language barriers, payment complications, and a lack of proper support. sin45 was built to fill exactly that gap. We wanted people in Bangladesh to enjoy world-class gaming from home — topping up via bKash, communicating in Bangla, and getting help from our support team whenever they need it.
Today, sin45 is home to players from virtually every part of the country — some are into cricket betting, others love slots, and many enjoy Live Casino. We keep improving our services to meet the needs of every user.
Sin45's beta version launched for Bangladeshi users with a small team. Within the first month alone, over 10,000 people signed up.
After integrating local mobile banking, transactions on sin45 became far more seamless. User numbers grew fivefold that year.
Live betting for cricket, football, and more was introduced. Record traffic was recorded during Bangladesh national cricket matches.
After the Android and iOS apps launched, sin45's mobile user base doubled in just three months.
Sin45 is now one of the most popular online gaming platforms in Bangladesh, with thousands of new members joining every day.
