Do I need an account to play?

No. Choose the rules, your side and a level, then press Play — or tap a square and you start as X. An unfinished game is kept on this device, and Leave never counts as a loss.

What is the difference between the two rule sets?

Freestyle: five or more in a row wins. Blocked ends (the Vietnamese caro custom): a five that is blocked by your opponent at both ends does not count. The edge of the board never counts as a block.

How strong is the computer?

Four levels. Beginner sometimes forgets to block. Easy and Medium play solid shape. Hard also looks at your best reply before choosing its move.
