To open a 21 2d account, you provide a username, email address, mobile number, and password. We use this information to create your account, send verification codes, and communicate important updates about your account.
After registration, we require KYC (Know Your Customer) verification. You'll upload a government-issued ID and proof of address. This process confirms your identity and age, and typically completes within a few hours. Once verified, you can deposit funds and begin using 21 2d.
Your 21 2d account dashboard gives you full control over your settings. You can update your password, enable two-factor authentication, view your transaction history, and manage your payment methods. You can also review your account balance, pending bets, and withdrawal requests in real time.
We recommend enabling two-factor authentication to add an extra layer of security to your login. You can also reset your password at any time from the login page if you forget it. All account changes are logged for your security.

Games and betting
RTP stands for Return to Player. It's a percentage that shows, over a very large number of spins, how much of all money wagered on a slot game is returned to players as winnings. For example, a slot with returns an average of 96 cents per dollar wagered over time.
RTP is a long-term statistical measure, not a guarantee for individual sessions. Each spin on 21 2d slot games like Aviator, Sweet Bonanza, Gates of Olympus, Fortune Tiger, and Mahjong Ways is determined by a random number generator. You can find the RTP for each game in its information panel.
