Yes. Choose one player in the CPU match and try to clear the table in as few turns as you can.

How do the CPU levels differ?

In how many cards they remember. The weak CPU remembers only the last few, the strong one cards turned up much earlier.

What happens if a player leaves during a game?

The CPU takes over for them, so the game does not stop. Online, you have 20 seconds per card; if time runs out, a card is turned for you.

Concentration (Shinkei Suijaku) rules: remember the cards and make pairs

A memory game: turn up two face-down cards at a time and collect pairs of the same number. A pair lets you go again, and whoever collects the most pairs wins. You can also try alone to clear the table in as few turns as you can, and play CPU players with three levels of memory.

Basic rules of Concentration

All 52 cards (or 26: spades and hearts only) are laid out face down.
On your turn, turn up two cards. If they have the same number, you take them and turn up two more.
If not, both are shown to everyone and turned face down again, and the next player takes a turn.
When every card is taken, the player with the most pairs wins. The same number of pairs shares a place.
Alone, your score is how many cards you turned to clear the table.

How to play on Asobi Lounge

On your turn, press the cards you want to turn up. After two, you see whether they make a pair.
Everyone sees the cards turned up. Two cards that did not match stay face up until the next card is turned.
Your best score alone (the fewest cards turned) is kept in this browser.

Tips

Remember where each number was turned up. A number you have seen once helps you on your second card.
Turn an unknown card first; if you remember where its pair is, turn that one next.
With 26 cards a game is short, which is good for practice and for playing alone.
