Common mistakes to avoid when using bonuses
Many players make a few avoidable mistakes after receiving a bonus that they later regret. Knowing these in advance can save you a lot of trouble.
Trying to withdraw without understanding wagering
Attempting to withdraw immediately after receiving a bonus will not work. Winnings from a bonus cannot be withdrawn until the required amount has been wagered.
Claiming multiple bonuses at the same time
Trying to keep more than one bonus active at the same time will generally result in only one being applied. Read the terms of each bonus separately.
Claiming a bonus after it has expired
Each bonus has a specific validity period. If it is not activated in time, the bonus may be cancelled.
Depositing below the minimum amount
No bonus applies to deposits below ৳200. The minimum deposit requirement for each bonus must be met.
Applying all bonuses to the same game
Some bonuses are restricted to specific game categories. For example, the sona Slots Festival Bonus can only be used on slots — not on crash games.
Accepting a bonus without reading the terms
Each bonus has its own rules. Reading the Terms and Conditions carefully will prevent any confusion later on.

Aviator and other crash games
Aviator (Spribe) is one of the most popular crash games at sona, with a maximum RTP of 97%. In the game, a plane flies while a multiplier increases — cash out at the right time to win.
A key feature of crash games is that each round is short, so it is possible to meet the wagering requirement relatively quickly using your bonus balance. However, placing larger bets fulfils the requirement faster but also increases the risk.
sona also has various offers for cricket betting and the Fishing Koi Fish game — there are separate bonus sections for players who enjoy different types of games.
