At its core, a Deposit Bonus is a bonus or reward that a casino or betting institution gives to an Estonian resident depositing funds into an account. The bonus itself depends on the institution, as do the terms and conditions for it. Generally, a deposit bonus will come as either a percentage of your deposited amount (up to a certain amount) or it will be a ‘no deposit’ bonus, meaning no deposit is necessary to activate the bonus. It is important to check the terms and conditions of the bonus carefully before deciding whether to take advantage of it.
