How to Play Thirty One

Thirty One pulls you into a fast, satisfying card game where every draw and swap feels like a small decision worth making. It suits anyone who enjoys classic rummy-style games and wants a challenge that grows as they do.

Open the app and pick one of the five game modes
Choose a difficulty level that matches your confidence
Draw or swap cards to build the strongest single-suit hand you can
Knock when you think your hand beats the table
Review your stats after each session to track your progress

Controls

Play is handled through straightforward card taps and menu selections, keeping the focus on your decisions rather than on learning the interface.

Scoring

Hands are valued by the total pip count of cards sharing a suit, with 31 being the perfect score — the closer you get, the better your position at the knock.

When does a round end?

A round ends when a player knocks, triggering a final reveal where every hand is compared and the lowest score takes the penalty.

Tips & Tricks

Knock early on lower difficulty levels — the AI tends to improve its hand quickly if you wait
Track which suits are appearing in discards; that tells you what your opponents are unlikely to hold
In modes with multiple lives, a conservative knock on a middling hand is often safer than chasing 31
Check the statistics screen regularly — your knock timing and win rate by mode reveal exactly where to focus
