It’s always fun to get extra playing money from an online casino. Sometimes you can get some by making use of a deposit bonus, but there are also other types of promotional offers that will provide you with a bonus on the house. For example, Klaver Casino has a nice offer this Friday with which you can earn some free playing money very easily. The underlying idea for this promotional offer is very simple: Start playing on slots and as soon as you have placed 100 euros or more in bets then you will get 10 euros of bonus on the house at Klaver Casino. That is a much better deal than it seems and we will explain why that is the case.
