You can't open a "play money" account on Svenska Spel and it is not possible to
just look around. What I can do is provide you with pictures of the lobby and a table.
These shots are taken during this morning and the total numbers of players logged in at the time was 1500. The highest stakes being played was 50/100 SEK with two players. I don't know why you would like to have an account there. The micro stakes are not easier imo compared with Pokerstars or Full Tilt and the sit n gos are imo a bit harder.
