Wild cards always match. 2. **2**### **Draw** If you can't or don't want to play, draw a card. If it matches, you may play it right away. Otherwise it's the next player's turn. 3. **3**### **Stack draw cards** You may play a +2 on a +2 and a +4 on a +4. Whoever can't stack draws everything and then plays on as usual. 4. **4**### **Jump in** If you have exactly the same card as the top card you may play it at once, even when it isn't your turn. The game then continues from you. 5. **5**### **Protection card** The protection card blocks action cards, even when it isn't your turn, as long as the action hasn't taken effect yet. Be quick! 6. **6**### **Call Olos** Before you play your second last card you have to call "Olos!". If you forget, you draw two penalty cards. ## **The action cards** Besides the number cards 1–9 in four colors, action cards shake things up. Wild cards have no color and match every card. - ![+2 (Red)](https://game-circle.de/game-circle-de/games/olos/card/design1/red/add_two_cards.webp) ### **+2** The next player draws 2 cards unless they play a +2 themselves. **15 penalty points** - ![Skip (Blue)](https://game-circle.de/game-circle-de/games/olos/card/design1/blue/skip.webp) ### **Skip** The next player is skipped. **15 penalty points** - ![Reverse (Green)](https://game-circle.de/game-circle-de/games/olos/card/design1/green/reverse.webp) ### **Reverse** The play direction changes. **15 penalty points** - ![Card swap (Yellow)](https://game-circle.de/game-circle-de/games/olos/card/design1/yellow/card_switch.webp) ### **Card swap** Swap your hand with a player of your choice. **15 penalty points** - ![Seat swap (Red)](https://game-circle.de/game-circle-de/games/olos/card/design1/red/position_switch.webp) ### **Seat swap** Swap your seat with a player of your choice. **15 penalty points** - ![Color wish](https://game-circle.de/game-circle-de/games/olos/card/design1/special/color_whish.webp) ### **Color wish** Wild: wish for a color. **45 penalty points** - ![+4](https://game-circle.de/game-circle-de/games/olos/card/design1/special/add_four_cards.webp) ### **+4** Wild: wish for a color, the next player draws 4 cards. **45 penalty points** - ![+8](https://game-circle.de/game-circle-de/games/olos/card/design1/special/add_eight_cards.webp) ### **+8** Wild: wish for a color, the next player draws 8 cards. **45 penalty points** - ![Spin](https://game-circle.de/game-circle-de/games/olos/card/design1/special/spin.webp) ### **Spin** Wild: everybody passes their hand on in play direction. **45 penalty points** - ![Protection card](https://game-circle.de/game-circle-de/games/olos/card/design1/special/protection.webp) ### **Protection card** Wild: blocks an action card, even when it isn't your turn. **45 penalty points** ## **Why Olos is fun online** ### **Bots on three levels** Play alone against easy, medium or strong bots. ### **2 to 16 players** From a game for two to the big party table. ### **Join anytime** Spectators can join between two rounds. ### **No waiting** If a player takes too long, the server draws for them.
