The Siel is easy to learn. It's incredibly fun. There is incredible chaos when a player shuffle the cards and they must re-distribute, and run two players at the same time around the table and then fight over the gun. The aim is to tap cards that match the currently applicable daytime. The time of day is determined from the supplied CD. So a game round is always exactly 17 minutes. (So a great game for in between) One discovers a particular card to have to walk around the table, or with a real rubber studs gun shoot at targets. The table should be free in the room, and the seats should not have any rest. When we played the last time I hit my knee so that I had a day later still pain. :-) But all this, including the thrill, fun and recommendable.
