These are tournaments with multiple entries. Their special feature is that you can make several entries either at the time of registration, or with a time interval (during late registration). Your separate entries will be located on different tables and will not depend on each other, which allows you to take several prize places.
If your entries are merged, your chips will also be combined into one stack. This is possible at any stage of the tournament and happens randomly if two or more of your entries are transferred to the same table.
In order to avoid the merge of several entries into one stack, we recommend that you register alternately, with some delay in time. The number of maximum registrations in a tournament is usually indicated in the tournament's lobby and most often ranges from 2 to 4 entries, sometimes up to 8.
