For Android: First, go to your phone's Settings > Security > Unknown Sources and enable it (or grant Install Unknown Apps permission). Then visit bk9900.best and tap the "Download App" button.

bk9900 displays odds in Decimal format by default — it's the easiest to understand. Here's an example:
Say the odds listed for Bangladesh in a match are 2.50. This means a ৳100 bet returns ৳100 × 2.50 = ৳250 (including your original ৳100). That's a net profit of ৳150.
The higher the odds, the lower the chance of winning — but the bigger the reward. Odds 1.10 indicates a near-certain favourite, but with lower returns. Odds 5.00 or higher means the underdog — a win pays out big.
To change your odds format: In Account Settings, go to "Odds Format" and choose between Decimal, Fractional, or American — whichever you prefer. Most bk9900 users in Bangladesh find Decimal the easiest to follow. During live matches, odds update continuously — Match Odds page for real-time odds.
