A real person can help
Stuck, found a bug, or have an idea? Email admin@qubesoftware.com and a real person at Qube, LLC will help.
Start playing
- Open cats.qubesoftware.com in your browser.
- Choose Play here to play on this device: seat two to eight players, any mix of people and bots, and pass the device around. A hand-off screen hides each hand.
- Or choose Play online to play with friends on their own devices.
- New to the game? How to play on the title screen explains the rules with real cards.
Play online with friends
- Choose a name and a pet. You only do this once on each device.
- Choose Start a new game. You're the host.
- Invite friends: tap the code to copy it, tap Link to copy an invite link, or show the QR code for a phone in the room to scan.
- Friends open the link, scan the code, or type the five-character code and choose Join game.
- The host can add bots, choose the game length, house rules, and turn timer, and then starts the game.
Anyone at the table can pause the game for everyone from the menu, and anyone can resume it. If someone's connection drops, a bot can keep their seat warm, and they can take it back with I'm back! To show the table on a TV or tablet, use Table view.
If a game code doesn't work
- Check the code: five letters and numbers, like KQ7PZ.
- A lobby that never starts closes after 24 hours.
- A game is deleted 14 days after its last move.
- If the host cancelled the game, its code stops working.
- A full table (eight seats) can't take more players.
- If the game asks you to update, reload the page (or update the app).
If there's no sound
- Tap the screen once. Browsers only start sound after a tap.
- Check the sound and music buttons on the title screen, and your device's volume.
- On iPhone and iPad, the silent switch or silent mode can mute sound in Safari.
- If sound stops after switching apps, tap the game again to bring it back.
If your recent games or settings are missing
The game saves your settings, recent games, and online name on this device, in this browser (or in the app). They don't follow you to another browser or device, and they are cleared if you use private browsing or clear this site's data. The game moved to cats.qubesoftware.com on October 11, 2026, so games saved at the old address didn't come along.
Report a player or a problem
If someone uses an offensive name or misbehaves in an online game, the host can remove them from the lobby before the game starts. You can also email us the game code, the name, and what happened, and we'll remove the game.
To report a bug, email admin@qubesoftware.com with:
- your device and browser (or app) version;
- the game code, if it was an online game;
- what you did, what you expected, and what happened.
A screenshot helps a lot.
Delete your data
- On your device:clear the site data for cats.qubesoftware.com in your browser's settings, or delete the app. This removes your settings, recent games, and online name and pass.
- Online games: they delete themselves, 24 hours after creation for a lobby that never started and 14 days after the last move for a game. To delete one sooner, email us the game code and the name you played under.
There are no accounts, so there is no account to delete. Read the Privacy Policy for the details.
Requirements
The game runs in an up-to-date version of Safari, Chrome, Edge, or Firefox on a phone, tablet, or computer, in portrait or landscape. Online play needs an internet connection. Pass-and-play games and games against bots run on your device, so they keep going if your connection drops.
App Store and Google Play
When the apps are available, Apple and Google process purchases made through their stores and decide refund requests. Qube, LLC can't approve or guarantee a refund. See Apple's refund instructions or Google Play's refund instructions.
