Most of them. There are one or two Indian online casinos which aren’t prepared to accept MasterCard deposits (although they will likely accept VISA), but they are minimal in number. Players shouldn’t encounter any problems finding somewhere to deposit using MasterCard.
Most Indian casinos are well licensed and regulated. As long as your casino has a good track record with security and safety, and bears a valid gambling license out of a respectable jurisdiction, it should be safe to deposit there, too.
No. Unlike VISA, which also accepts deposits made using Electron and Debit card options, MasterCard’s own debit card method (Maestro) cannot be used just because a casino accepts MasterCard. Indian casinos must specifically offer Maestro as a separate method if you wish to use this option.
It is possible, though not guaranteed. Some casinos have no charges or fees on deposits and withdrawals made using MasterCard, but some will charge you. Similarly, there may or may not be a charge attached via the bank which issued your MasterCard. Those sites which do charge fees, generally only do so for cashouts, and seldom set it to higher than 2.5% of the total withdrawal sum. Even then, there is often a cap on the maximum charge a casino can put in place for cashouts.
MasterCard deposits land instantly in your account. Withdrawals made using this method typically take the same amount of time as other credit card and bank transfer withdrawal options. In short, this means you can expect processing times of 3-5 business days before you can get hold of your winnings. Royal Panda Casino is one of the online casinos in India where you can deposit with Mastercard!
