If you cash out in time, your stake is multiplied by the current value. If the plane disappears before you cash out, your bet is lost. The outcome is determined by a provably fair algorithm.

21tk offers a welcome bonus to newly registered players on their first deposit. The exact bonus percentage and maximum bonus amount are displayed on the promotions page at the time of your registration. To claim the welcome bonus, opt in during or immediately after making your first deposit. Bonuses are subject to wagering requirements before withdrawal — please read the full bonus terms before claiming.

A wagering requirement is the number of times you must bet through a bonus amount before it can be withdrawn as real cash. For example, a ৳1,000 bonus with a 20x wagering requirement means you need to place ৳20,000 in eligible bets before the bonus converts to withdrawable funds. On 21tk, individual game types may contribute different percentages toward meeting the wagering requirement — slots typically count 100%, while live casino games may count less.
