First of all, casinos with a minimum deposit are good for newbies. For those who have never played slot machines before and want to try. Judge for yourself: if you make a deposit of at least £1 casino deposit, you can start a productive game, and it will cost you almost nothing. After spinning some slot at the minimum bet in a casino with a small deposit, even with such a balance, you have a chance to increase your bankroll by a certain amount, and so on increasing.
Foreign sites with slot machines often do not have such loyal conditions as casinos with ruble rates. After all, European or American establishments are designed for Europeans and Americans, respectively, and they have their own ideas about what the minimum rate is. They just dont play for such small amounts that are relevant to us. Therefore, it is almost impossible to find among foreign portals those that support casino bets from 5. You can find a ton of casinos with a minimum deposit of 5 - this is the generally accepted average minimum deposit amount.
