No, classic straight Okey does not require a minimum-point opening; you simply arrange all your tiles and finish in one move.

Unlike 101 Okey, where you must lay down melds worth at least 101 points before you can play tiles on the table, straight Okey is played entirely on your rack. You keep your groups hidden until you go out, then reveal a complete hand of runs and sets with a final discard. This makes classic Okey faster and simpler, which is why many newcomers start with it.
