Match bonuses (deposit or percentage bonuses) are actually among the most commonly used in casinos. One of the reasons for such popularity is that a casino match bonus allows fewer opportunities for bonus abuse by advantage players. To compare, no deposit casino bonuses allow high degree of abuse by the players, which makes them less popular and offering much lower profits.
A casino match bonus provides matching the player's deposit with certain percentages of this total deposit. These percentages can make from 50% up to 500% and even 1,000% in some online casinos. One should note that such high match bonuses are only available with slots and lottery-type games like keno.
Match bonuses offered as sign up bonuses come as a single event. But casinos may actually offer some recurrent match bonuses to attract the players to continue playing.
As any online casino promotions, match bonuses feature certain wagering requirements. For example, a casino may require 50% casino match bonus with 20 times wager. Another requirement for match bonuses may be making a minimum deposit. Usually this minimum deposit amount is quite low - about $20 to $30. Prior to accepting a casino match bonus a player is supposed to get acquainted with all terms and requirements for a given casino and a certain game.
