I am confused

[cema]

Pay - paid, not payed
Play - played, not plaid

Is that a rule or an exception? (This being English, may not be that different.)

"This being English, may not be that different" - exactly! As someone pointed out, rules are in Russian. In English you either know, or you don't.
