All Fours is played by four players in two teams of partners who sit across from each other. Each player gets six cards, and the dealer turns up the next card to set trumps. Teams score for High (the highest trump out), Low (the lowest trump out), Jack (winning the Jack of trumps in a trick) and Game (the most points in the tricks you won: Ace 4, King 3, Queen 2, Jack 1, Ten 10). The first team to the winning score takes the game.

The player on the dealer's right looks at their hand and says Stand to play the turned-up trump, or Beg for a new one. The dealer either says Take one (the other team scores a point) or runs the pack: three more cards each and a new turn-up.

If trump is led you must follow trump if you can. If another suit is led you may follow suit or play a trump, but you can't throw off a different suit while you still hold the suit led. The full rules are in the app under Menu > Rules.

Catch the other team's Jack of trumps with a higher trump and your team scores the Jack's points. It is the sweetest thing in the game.

Signs let you tell your partner something about your hand, the way players wink and scratch at a real table: that you hold High, Low, the Jack, the Ten and so on. Only your partner sees a sign; the other team never learns that one was sent.

You start with a set of signs. More come in sign packs from the Signs Store in the app. Each sign is used up when you send it. At an online table the host decides whether signs are allowed.

• Sign packs (Silver, Gold, Platinum, Diamond, Carnival): one-time purchases that add signs to your account.
• All4s Pro: a yearly subscription that removes ads. It renews automatically until you cancel.

Playing the bots, playing with friends online and using the signs you own are always free.

Sign in with the same account you bought with, open the Signs Store and tap Restore purchases. Pro and your sign balance are tied to your All4s account, so signing in on the new phone brings them back. If you played as a guest, link an email to your guest account first (Profile) so you do not lose your purchases.

Subscriptions are managed by the store, not by us.
iPhone: Settings > your name > Subscriptions > All4s > Cancel Subscription.
Android: Google Play > profile icon > Payments & subscriptions > Subscriptions > All4s > Cancel.
Cancel at least 24 hours before the renewal date to avoid the next charge. Pro stays on until the end of the period you paid for.

Refunds are handled by the store you paid: Apple (reportaproblem.apple.com) or Google Play refunds. A refunded sign pack or subscription is removed from your account.

Check your connection and tap Restore purchases in the Signs Store. If that does not fix it, email us with the order number from your store receipt (Apple receipts start with M, Google order numbers start with GPA.).

No. You can play the bots without signing in, and play online as a guest. An email account keeps your name, stats and purchases safe if you change phones.

In the app: open Settings and tap Delete my account, then confirm. Your account and its data are deleted as described on the Delete your account page, which also explains how to ask for deletion by email if you no longer have the app. Deleting your account does not cancel a store subscription: cancel All4s Pro in your store account too.

At an online table, open the chat, press and hold the message (or tap …) and choose Report, then pick a reason (abusive or hateful, spam, cheating, inappropriate name, or something else). You can also press and hold a player's name at the table. The report goes to our moderators with the message and a few lines around it. Mute hides a player's messages for this table; Block hides them for good and also reports them. You can unblock players in Settings > Safety. For anything urgent, or abuse outside chat, email support@all4s.dreadrocksoftware.com with the player's display name and the time.

We have zero tolerance for objectionable content and abusive players. We review reports within 24 hours, remove the offending content, and suspend or ban the players responsible. See the Terms of Use.

Yes. Turn on Kids' chat in the chat settings and chat is limited to preset quick phrases and reactions: no typing, so no free text is sent or received. All4s is not directed to children under 13. See our child safety standards.

So we can tell you when a friend invites you to a table or it is your turn. You can turn them off any time in your phone's settings.

Only to scan a friend's table invite QR code. Nothing is recorded or uploaded.
