How to Play 9K Club

Step one: slide the board

Press an arrow key, or swipe across the board on a phone. Every tile slides that way at once, as far as it can go. Nothing is aimed and nothing is selected — you move the whole board or nothing at all.

Step two: push matching numbers together

When two tiles showing the same number collide, they become one tile showing the next number. That is the only way the ladder climbs: two 1s make a 2, two 2s make a 3, and so on.

Step three: keep the board tidy

After every successful slide, a new tile appears in a random empty square. That is the pressure in the game: if you slide carelessly, the board fills with odd numbers that cannot pair up, and a full board with no matching neighbours is the end of the run.

• Choose one corner at the very start and never let your biggest tile leave it.
• Prefer the two directions that push towards that corner.
• Before you slide, look for two or three pairs you can merge in the same move.
• Use Undo when a slide clearly went wrong — it is there for exactly that.

Step four: reach 9

Keep chaining merges and the ladder climbs. When the 9 tile appears, the club tells you the ladder is finished. You can carry on with the same board to push your score up, or start a clean run.

A worked example

Say your bottom row reads 4, 3, 2, 2 from the left, with your 4 in the bottom-left corner. Slide left: the two 2s merge into a 3, and the row becomes 4, 3, 3. Slide left again: the two 3s merge into a 4, giving 4, 4. One more slide left and you have a 5 in the corner. Three slides, one new tile on the ladder — that is the rhythm you are looking for.
