Scum — also known as President — is a climbing card game. Be the first to empty your hand: win the round and you're President next round, finish last and you're Scum. Play singles, pairs, triples, or quads, and beat the pile or pass.
You can play solo against AI opponents, or online with 2–16 players over Apple's Game Center.
No. Solo play against AI opponents works with no Game Center account and no internet connection. Tap Play Game from the main menu. Game Center sign-in is only needed for online multiplayer.
Online features require you to be signed in to Game Center. Open the iOS Settings app, go to Game Center, and make sure you're signed in with your Apple Account. Then reopen Scum — the online options will appear in the lobby.
Public room browsing also requires iCloud. Check that you're signed in to iCloud in Settings and that iCloud Drive is enabled for the device. If a room code isn't working, confirm the host is still waiting on the room screen — room codes stop working once the game starts or the host leaves.
Online games are turn-based: each player takes their turn in their own time, and you'll get a notification when it's your turn. If a player is taking too long, the host can set a turn timer when creating the game (1 hour to 3 days), after which that player's turn is played automatically. You can also send a nudge from the game screen.
Scum asks for notification permission after your first completed turn. If you declined, you can enable it in the iOS Settings app under Notifications → Scum.
When creating a game you can turn on optional rules:
Note that 2 is the lowest card and Ace is the highest in this variant.

Scum collects only the limited data needed for online multiplayer, uses no advertising or third-party tracking, and never sells your data. Full details are in the Privacy Policy.
