Olsen is the card game Norwegians learn around the kitchen table and on the cabin trip. It belongs to the Crazy Eights family, so if you know that game, you know most of this one. I made this version so I can play it with friends wherever they are, each on their own iPhone, iPad or Mac, and against the computer when nobody else is free. Match the top card by suit or rank. An 8 goes on anything, and you choose the next suit. If nothing fits, draw up to three cards before you pass. When someone is down to one card, the game calls Olsen for them, so everyone knows who to stop. The first one to empty their hand wins. PLAY WITH FRIENDS Invite up to three friends through Game Center. The round starts as soon as one of them has joined, and AI players can take the empty seats. Tap Rematch to go again at the same table, and the end screen keeps count of who has won the most rounds. If someone loses the connection, an AI player keeps their seat warm until they are back. Three of the achievements are only for games with friends. PLAY ALONE Take on one, two or three AI opponents on easy, normal or hard. They have names and a bit of personality, and the hard ones count cards. No internet needed, so it works on a plane or at a cabin with no coverage. LEARN IT IN ONE ROUND Never played Olsen? The tutorial plays a round with you and explains each move as it happens. The full rules are in the menu when you want to check something. FOR KIDS, ADULTS AND SENIORS Three themes with their own look and their own opponents. Leo the Lion and Bella Bear sit at the kids table, and the senior theme has larger text and Churchill as an opponent. PLAY IT YOUR WAY Tap a card twice, swipe it up, or drag it onto the pile. Cards that do not fit bounce back to your hand. On iPhone the whole game works with one hand. WHAT YOU GET • Up to four at the table over Game Center, each on their own device • AI players in the empty seats • Rematch and a running count of who wins • One to three AI opponents on three difficulty levels • Play offline against AI • Wild 8s that change the suit • A tutorial that teaches the game in one round • 23 Game Center achievements • Kids, adult and senior themes • iPhone, iPad, Mac, and Apple Watch for a quick solo round • English and Norwegian Deal the cards and see who gets to say Olsen first.
