Questions about playing Concentration online
How many can play Concentration online here?
One is enough, and up to 8 can sit down at the same table. There are no bots here — each of you plays your own hand against the deal.
Can I play Concentration against the computer?
No, and it would not help. At Concentration you play the deal rather than the other seats, so a bot beside you would be playing its own hand and you would only be waiting for it.
Does it cost anything?
No. Every table here is free, there are no ads, and nothing is tracked.
Do I need an account?
Only to open a table. Joining one never needs an account — anyone you send the code to sits down as a guest.
Does Concentration work on a phone?
Yes. It runs in the browser on a phone, a tablet or a computer, and there is nothing to install.
