The best beginner strategy in Okey is to plan groups ahead, protect your joker, and watch the discard pile.

Decide early whether your hand leans toward runs or sets, and keep tiles that can go multiple ways. Hold the okey until you have a clear finish, since it completes any group and finishing on it pays double. Avoid discarding tiles opponents just picked up, and prefer throwing pieces whose matches are already gone. With practice against bots, these habits become automatic and your win rate steadily climbs.
